Log of changes (libticables):

- 01/11/2016, version 1.3.5: debrouxl
	- on MacOS X, force reenumeration upon device reset, because it isn't automatic, which breaks e.g. communication with the Nspire. Reported by STV and Adrien Bertrand.
	- don't declare a struct serial_struct instance if the header defining its type is not available. Fixes a build error under Alpine Linux.
	- add initial support for 84+T model, fix several bugs in 82A support.
	- in the torture tests, use __LINE__ instead of a counter, and remove some of the blank lines. Suggested by Benjamin Moody.
	- use ticables_cable_get_device_info to detect model.
	- add API for retrieving device info from an open cable handle.
	- add empty implementations of a TCP client and TCP server cable pair; in ticables_probing_finish(), free all indices allocated by ticables_probing_do().
	- inline our trivial logging functions, which enables checking arguments wrt. format (without putting format annotations, that is), fix several bugs uncovered by this change; remove all remaining occurrences of TRYC from libticables.
	- add Travis CI integration.
	- replace AC_PROG_LIBTOOL with LT_INIT.
	- synchronize DUSB vpkt array in libticables; add several bounds checks.
	- add per-handle pre / post receive and pre / post send hooks functionality, add corresponding torture tests.
	- update CONFIG, promoting the group-less setup for modern udev-based distributions instead of the group-based setup.
	- make FileContent.num_entries, FlashContent.num_pages, TigContent.n_vars, TigContent.n_apps, CableOptions.timeout, CableOptions.delay unsigned; have several functions of the API take or return unsigned int instead of int.
	- fix two sets of bugs reported by Benjamin Moody; reduce code duplication by introducing noop_*() functions in link_nul.c, and use them from other link_*.c files; remove long-dead src/win32/link_slv2.c file; whitespace changes.
	- fix two old bugs related to libusb 1.0 context teardown.
	- add a number of helper functions for symmetry, add them to the torture tests, and fix memory leaks & memory errors in the torture tests and/or the libraries.
	- fix -Wmissing-prototypes warnings, as suggested by Benjamin Moody; fix the build on FreeBSD 10; cleanup for MacOS X (twice, Adrien "Adriweb" Bertrand reported a buggy change).
	- on Windows, enable DTR power supply, to fix operation of some third-party GrayLink cables.
	- in the README, mention that autoreconf needs to be run before ./configure can run. Reported by SirCmpwn.
	- new API for probing USB devices.
	- minor non-functional improvements to data logging.
	- add some 83PCE / 84+CE / 84+CE-T and 82A support, and perform the usual software engineering work.
	- fix dozens of more (UAF, DF, OOB accesses) or less (tiny memory leaks, dead code) severe issues reported by Coverity Scan. Several other issues found by code inspection.
	- add ticables_free_usb_devices() as counterpart to ticables_get_usb_devices(); use it to fix a minor memory leak in ticables_probing_do(); make it part of the public API; add torture test.
	- Add .gitignore, remove globbing from libtifiles makefile.am, fix a warning in libticables error.c, remove unneeded config.h.in
	- kick out remaining code for long-dead Linux-specific cable based on special device /dev/tiusb*.
	- add ticables_get_device() and ticables_set_device() APIs and corresponding functions in CableFncts. Suggested by Jonimus.
	- merge bsd/link_gry and bsd/link_ser into linux/link_gry and linux/link_ser, thereby reducing code duplication.
	- attempt to cope with NULL CableFncts pointers in improper CableHandle structs; get rid of a number of TRYC.
	- add ticables_supported_cables() API, suggested by Jonimus.
	- review error files. Have ticalcs_error_get() uniformly use g_strconcat/g_strdup like tifiles_error_get() and ticables_error_get(), instead of strcpy+strcat+g_strdup with a statically-sized buffer on the stack.
	- produce export (def) files on Win32.
	- remove more auto-generated / copied files from the repository; upgrade gettext dependency to 0.18 (from May 2010).
	- in torture tests, print local traces to stderr instead of stdout. This restores `make check` output with recent autotools versions.
	- remove auto-generated configure & Makefile.in from the repository.
	- in order to prevent implicit overlinking, use more Requires.private in pkgconfig definitions, instead of Requires. Patch mainly by Tijl Coosemans.

- 31/03/2013, version 1.3.4: debrouxl
	- add "torture test" programs for testing how functions of the public API react to NULL parameters.
	- apply downstream Debian patches by Aurelien Jarno <aurel32@debian.org> for fixing FTBFS on sh390x (Debian bug #641092), sh4 (Debian bug #567679) and sparc64 (Debian bug #596601).
	- regenerate with Automake 1.11.6.
	- use LF line endings throughout the sources.
	- convert README to UTF-8.
	- fix some spelling errors (or at least, infrequent forms) reported by Lintian (through Albert "alberthro" Huang) and rpmlint (through TC01).
	- fixes for i18n problems reported by Benjamin Moody.
	- add the keypresses command to libticables' hex2nsp.
	- improved support for "raw mode" external linking, by Benjamin Moody, thanks to two new functions for getting and setting both lines simultaneously.
	- expand torture tests, and perform minor fixes.
	- on Windows, load libusb-win32 dynamically if available, and fail gracefully if it's missing. This way, it's possible to make driver-less emulator (tilem, tiemu) installers, which don't require elevated privileges. Change cross-compilation maintainer script.
	- fix a number of problems related to unaligned reads/writes and left shifts of count >= width of type; fix more compiler warnings reported by clang.
	- fix a couple warnings turned errors [by the addition of -Werror=implicit-function-declaration to the maintainer scripts] in the Windows code.
	- try to fix an elusive BSOD, reported by multiple persons, possibly introduced by SVN r4428: don't pass $CFLAGS and $CPPFLAGS to $CC when compiling dhahelper.

- 14/12/2011, version 1.3.3: debrouxl
	- more fixes in the libusb 1.0 backend, following the introduction of the asynchronous code.
	- update CONFIG once more, to keep up with changes in udev...
	- add several messages in the Linux device detection code, and unify / update messages and translations.
	- eliminate explicit usage of stdout.
	- upgrade COPYING files and FSF addresses embedded in files, so as to make rpmlint happier.
	- upgrade libusb-win32 and INF files to a version that 1) allows stable use of the filter driver and 2) makes Nspire support useful again on Windows. Cleanup the tree.
	- reconfigure with autoconf 2.68 and libtool 2.4.
	- reconfigure with libtool 2.4.2.
	- take a whack at hundreds of NULL pointer dereferences by sanitizing function arguments.
	- fix multiple global buffer overflows in normal usage spotted by AddressSanitizer; comment several unused functions.
	- move the workaround for file transfers of peculiar sizes mainly to libticalcs.
	- port the change to file transfers of peculiar sizes from the libusb 0.1.x to the libusb 1.x backend.
	- upgrade version of gettext to 0.17, released in late 2007.

- 28/05/2011, version 1.3.2: debrouxl
	- remove autogenerated Changelog files and empty TRANSLATORS files.
	- change encoding in .rc file.
	- compiler warning fixes
	- Sync src/bsd with src/linux
	- Include <stdlib.h> (calloc,free) from link_usb.c
	- Parallel port works differently on *BSD than Linux.
	- add Nspire 2.x OS support, based on patch by Brian Johnson (SF bug #3001104).
	- add powerpc64-*-linux-* and powerpc64-apple-darwin* to configure.ac (reported by "blah3" in SF bug #3002220); perform minor documentation updates.
	- fix a number of compiler warnings, memory leaks, unclosed files.
	- minor changes to make autotools definitions work with both libtool 1.x and 2.x.
	- use AM_GNU_GETTEXT_VERSION to use a consistent version of gettext (namely 0.16, released in late 2006).
	- prevent a number of NULL dereferences, and turn abrupt program aborts such as assert() and exit() into tests + ti*_critical().
	- reconfigure under Debian Squeeze with Autoconf 2.67 and Automake 1.11.1.

	Some clean-up and fixes in the virtual link cables.
	Removed windows.h dependancy in timeout.h.
	Fixed some MinGw compilation issues.

	Added USB direct cable support (lib-usb).
	
- 11/06/2004, version 3.8.6: jb
	Added support for x86-64 (configure.ac, configure).

- 22/05/2004, version 3.8.6: roms

	with direct link support.
	
- 05/05/2004, version 3.8.5: roms
	Bug fix in the verbose.c compatibility support (DISPLAY).
	Merged Tijl's patch: does not build or use libusb support if libusb
	not detected.
	link_dfl changed into link_nul (null cable). Added null method and null
	port in order to implement a pure null cable.
	Default settings are now set to a null cable/port.
	
- 24/04/2004, version 3.8.4: roms
	Added buffered write support to the SilverLink / Win32 module. 
	Driver 3.0.2.1 is needed. Tested with various transfers.

- 21/04/2004, version 3.8.3: roms
	Added full/partial BUFFERED_W (heuristic) support to get the best of
	both worlds ! Tested with group, idlist, clock, backup, 
	FLASH apps (s/r), ROM dump and FLASH os.
	This really speed-up FLASH app transfer (sending).
	Done the same work for tiglusb kernel module support. This stuff will 
	be moved into the module later...
	
- 17/04/2004, version 3.8.2: roms
	Bug in lib-usb support: wrong timeout passed to libusb (1/10 of
	value) => short timeout !
	Discovered the same bug in tipar/tiser/tiusb kernel module !

	Note: USB support default behaviour is: BUFFERED_R=1 & BUFFERED_W=0.
	Using BUFFERED_W make FLASH sending faster but communication is less 
	reliable.
	
- 08/04/2004, version 3.8.1: roms
	Redirection of stdout/stderr.
	Weird: we were using tilp/ticable.h. It should be linux/ticable.h.
	In fact, modules use tilp/ but built-in uses linux/.
	Modules will be modified to linux/.
	
- 22/03/2004, version 3.8.0: roms
	Splitted sources according to target and cables.
	Tested under Linux with:
	- GreyLink: api: ok
	- BlackLink: asm: ok, ioctl: ok, module: ?? 
	- SilverLink: ioctl: ok, module: ok
	- Parallel: asm: ??, module: ??
	Wake-up sequence removed from serial & parallel cables because it 
	perturbates communication start-up.
	
	Beware: Mac OS-X support has been moved to the new architecture but 
	has not been compiled !!!

	Bug in serial link support (mode asm: no timeout on ser_get).
	Bug in parallel link support (mode asm: no timeout on par_get).

	Added ability to immediately flush log file to disk.

- 28/12/2001, version 3.0.4:
	ugl_link: libusb support tested.
	
- 26/12/2001, version 3.0.3:
	Removed DLPortIO for PortTalk (www.beyondlogic.org) which brings about
	more advantages: source code available, smaller, faster, ...
	tig_probe implemented.
	
- 24/12/2001, version 2.2.5 -> 3.0.2:
	I have swapped ticable_set_param and ticable_set_param2 for JB.
	Error code values changed.
	I have changed the naming scheme about the LinkCable structure.
	I have cleaned up the source code.
	Moved pause.h from libticables to libticalcs.
	
- 21/12/2001, version 2.2.4 -> 3.0.1:
	I have changed my motherboard (SiS + Duron800MHz) which have been
	broken by my brother. I have finished the I/O management.
	ugl_link.c: libusb and kernel module support splitted.
	Compiled and fixed for Win32.
	
- 18/12/2001, version 2.2.3 -> 3.0.0:
	I have increased the major number: I have planned many enhancements, 
	modifications, clean-up, ...
	
	I/O management and probing improved.
	I have added 2 new functions: ticable_init & ticable_exit. The first 
	one is primarily used for detecting & listing available I/O routines.
	This version is still backward compatible if the 
	ticable_get_default_param function is called (and it should be...).
	
- 17/12/2001, version 2.2.2:
	JB has written a support of the SilverLink (TIGL-USB) with the libusb.
	I have merged his patch.
	ticable_probe: I have added a check for mouse (no risk to hang up your
	mouse, at least under Linux).
	
- 11/12/2001, version 2.2.1:
	Consistency: ticable_set_param modified again: use a struct but
	ticable_set_param2 use a pointer on structure.
	
- 20/11/2001, version 2.2.0:
	Win32 projects are now distributed with source code.
	get_default_param returns a GreyTIGL link cable on COM2.
	
- 19/11/2001, version 2.1.9:
	French PO files have been updated (i18n).
	Tested under WindowsXP with success ! WindowsXP seems to be a NT based
	system rather than a Windows9x/Me system.
	
- 17/11/2001, version 2.1.8:
	Recompiled under Win32.
	
- 15/11/2001, version 2.1.7:
	Consistency: ticable_set_param use a pointer on struct now.
	
- 08/11/2001, version 2.1.6:
	Added a m4 macro for checking libticables in configure scripts.
	
- 27/10/2001, version 2.1.5:
	warnings fixed.
	
- 23/10/2001, version 2.1.4:

	directly use a parallel/serial link cable.
	
- 19/10/2001, version 2.1.3:
	Updated to Am/Ac2.52: configure.in renamed into configure.ac.

	Some missing error codes have been added.
	
- 17/10/2001, version 2.1.1:
	Logging mechanism improved (logging.*).
	After some tests, it seems that transfer are more reliable if we
	send byte per byte rather than per packet. I think (an hypothesis) that
	we should not try to get data if link cable's buffer does not contain
	data.
	By sending byte per byte, we ensure a fast reply of the calc and so
	we ensure that link cable's reading buffer are not empty.
	
- 16/10/2001, version 2.1.0:
	TIGL-USB Linux support improved. There is still one problem: receiving
	variables by block crashes. Else, all other things work (ready, screen,
	send vars, backup, ...)
	
- 13/10/2001, version 2.0.9:
	I have written the TIGL-USB Linux support for testing the device
	driver.
	Read & write operations are buffered.
	The TIGL-USB Linux kernel driver works fine but it is a bit slow...

- 12/10/2001, version 2.0.8:
	The TIGL-USB Win32 kernel driver works fine now. I have merged Win32
	support. Note: this version is not very clean because it includes
	some kernel definitions & exports as well as a DDK library.
	To do: write a DLL front-end and package it.
	The library manages only 1 USB link cable. A future version will be
	able to manage up to 4 USB link cables.
	
- 06/10/2001, version 2.0.7:
	The TIGL-USB Win32 kernel driver is under development.
	
- 30/09/2001, version 2.0.6:
	The TIGL-USB linux kernel driver works ! JB has chosen the 
	following nodes: /dev/usb/tigl[0-15] so I have modified the lib
	consequently.
	
- 29/09/2001, version 2.0.5:
	TIGL-USB support added.
	
- 17/09/2001, version 2.0.4:
	Routines for probing ports/cables have been fixed (many bugs under 
	Linux).
	Thing to fix: if a mouse is connected on a serial port, the probing
	routine hang-up the mouse...
	Anyways, these routines need to be cleaned, improved and securized.
	
- 14/09/2001, version 2.0.3:
	The test program have been tested on Win32 platforms.
	I have added a check in ticable_set_cable: user is informed if he
	tries to use a port which is not compatible with the cable.
	The cabl_int.h file has been completed. It contains now all exported
	functions.
	I have removed many warnings under MSVC (none to level3).
	
- 13/09/2001, version 2.0.2:
	I have tested the library under Win32 (9x/NT).
	The library is now stable and clean.
	Doc has not been updated yet.
	Headers are now C++ compliant (extern "C").
	Thomas Wolf <two@chello.at> has written a BCC32 v5.x (or C++Builder5+)
	wrapper for the libticables. He has also bring about some modifications
	to the libticables that I have merged.
	
- 12/09/2001, version 2.0.1:
	I have widely cleaned up I/O management, interface and headers.
	I have also removed old routines.
	
- 11/09/2001, version 2.0.0: compatibility broken -> v2.x.x
	library is now easier to use: simply pass the port to use (a name)
	and the lib find device name & address.
	The library is backward compatible with programs which use the old
	library. Nethertheless, programs need to be recompiled.
	
- 10/09/2001, version 1.8.5: a bug fix in the dev string (too short).
	Some modifications for making the lib easier to use.
	The test_libticables program has been updated.

- 02/06/2001, version 1.7.7: some functions for managing raw access have been added as well as functions for checking sending/receiving. They have been added for making easy emulator support which can require a direct access.
	
- 19/05/2001, version 1.7.6: VTi link support improved and modified. TIEmulator virtual link re-implemented under Win32. Some code have been cleaned.

- 06/03/2001, version 1.6.0: I have boosted the libticables library for I/O transfers. A great thanks to Timothy Singer <tsinger@uoregon.gladstone.edu>, the FastLink's developer, who allows me to see why my routines was slow under Windows9x. Conclusion: use GetTickCount() instead of clock() under Win9x greatly improve speed.
