/*
 *
 *  This file, included from ntop.h, contains ALL common #define statements.
 *
 *     Changes here affect how ntop compiles.  This includes features that are
 *     enabled, etc.
 *
 *  Names have at least one part that defines their "type".  Listed below in the order
 *  they are most frequently changed.
 *
 *  PARM -- any "PARM" item is an internal tuning item, e.g. one that must be set at
 *  compile time and can not be overridden at run time.
 *
 *  MAKE -- MAKEs are like PARM, but set based on other factors like the os, absence
 *  of other values, etc.
 *
 *  DEBUG -- any "DEBUG" item is not normally set, but if #define(d) causes additional
 *  output fron ntop of a debugging nature.
 *
 *  CONST, LEN and MAX - these are arbitrary values, limits and lengths of fields
 *  (buffer size, ethernet address, et al) and arrays.
 *
 *  FLAG and BITFLAG -- are various constants and flags.
 *           FLAG is a numeric/char value used to mean something
 *           BITFLAG is a value used to test/set a specific bit in a value
 *
 *  HTML -- an "HTML" item is the name of a page produced by the ntop web server.  Using
 *  these constants ensures that the same name is used for testing and for including in
 *  generated html.  Note that this includes the graphics we use (.jpg, .gif and .png)
 *  regardless of whether it's a generated "page" or just a static included image.
 *
 *  CFG -- any "CFG" item is set in config.h by ./configure indicating that ntop was
 *  requested to be compiled with a particular configuration.  These are not defined in
 *  this file.
 *
 *  HAVE -- any "HAVE" item is set in config.h by ./configure indicating that the .h and
 *  .a/.so tests found we have a particular file or library during the testing process.
 *  HAVE items are not defined in this file (they're in config.h).  However -
 *  Note that we don't differentiate in the code between the automatically generated
 *  singular items (HAVE_SSL_H) and the composite ones (generated from a bunch of tests,
 *  HAVE_OPENSSL).  Forced and/or Composite items should be defined here.
 *
 *  DEFAULT -- any "DEFAULT" item is the standard, default value of a global data item.
 *  This can be over-ridden (usually) by a command-line pararameter at run-time.
 *  These go pretty much last so they can use values from other classes.
 *
 *  -- any MISSING or EXTERNALLY named item, obviously, has to have the proper missing
 *     or externally named name.  These are grouped after the ntop stuff...
 *
 *  Note that with this initial version (01-2003), there is something less than 100%
 *  adherence to this.  Any corrections, comments, (hopefully) documentation would be
 *  greatly appreciated.
 *

 *   The relative order is important for makeHostLink()
 *       Items we know definitively should be positive
 *       NONE should be zero
 *       'fake' entries < zero
 *
 *   So the Type starts as NONE, and if it's still that, makeHostLink()
 *   can try other sources in the tables to find the 'name'.
 *
 *   If we know, explicitly, the type of an item then hostResolvedNameType
 *   becomes >0  and makeHostLink() must respect it.
 *
 *   Items for which we shouldn't create a host entry are <NONE, i.e. FAKE.
 *
 *   Use broad ranges for this ... the actual #s don't matter, only the
 *   relative values.
 *
 *   So...  1.. 9 are low level (frame, transport) addresses such as the
 *                        Ethernet MAC address.
 *
 *         11..19 are basic protocol addresses, such as IPX or IP
 *
 *         21..29 are high level names, such as DNS name or NetBIOS name
 *
 *  Use the last digit for 'family' so tcp/ip over ethernet would normally
 *  flow MAC (9) to IP (19) to (DNS) NAME (29)
