TODO
* libfvde
  - optimize XML plist parser to directly generate keys
* fvdeinfo
  - print logical volume identifier
* format support
  - 2x 0x001a block with same serial, where second one contains size of 2x extents
  - and first 1x extent, another image only the size of 1x extent.
* volume offset detection
  - fallback check if volume data is before encrypted metadata?
* pyfvde
  - pyfvde_volume_get_size replace by pyfvde_volume_get_logical_volume_size ?
  - add functionality to set encrypted context plist
* complete libfvde_xml_plist
  - rename XML plist key to element
  - improve error reporting regardin not being able to read the plist
    versus not being able to read specific elements.
* read 0x0012 and 0x001d/0x0505 pairs and compare sequence numbers
* add support for block chains 0x0019, 0x0024
* add support from compressed XML plist 0x0019
* print metadata block offset for debugging
* check for partial encrypted volumes
* debug print block type description for 0x0405 metadata

* Make sure to detect PassphraseWrappedKEKStruct in different locations within
  the XML
* add password keep
* remove deprecated functions
  - libfvde_volume_read_random
* double check 0x0505 findings with debug logs
* git version
  - make sure dependent local libs are in git
  - fix synclibs.sh for libfvalue Makefile.am
* merge reading metadata and encrypted metadata ?

* API add volume identifier functions

* add handling of FVDE volumes with corrupt metadata, e.g. file header

* read and compare second physical volume header

* move initialize of volume specific runtime data to open and clean up to close
* store passwords as hashes?
* libxml
  integrate into packaging system
  print status info in configure
* split off AES KEK functions
* fvdemount add osxmount support
* code clean up
  - check for leading spaces
  - check for () without spaces
  - check for = alignment
  - check for if ( instead of if(
  - check error codes
* check README files
  - make sure pkg-config is mentioned as a dependency
* add debug output
  - encryption method
  - checksum algorithm

Future considerations:
* how does tie into CS volume management
  - rename library to libvcs ?
  - rename FileVault to CoreStorage ?
