Log Message:
-----------
** code courtesy of Christophe Fergeau **
* src/itdb_itunesdb.c (mk_mhbd): write extended header needed
for new iPod Nanos (3G Video) and iPod Classics.
src/itdb_device.c
src/itdb_device.h: Code to parse SysInfoExtended and SysInfo
for the FireWireGUID. You must either copy the iPod
description XML file to Device/SysInfoExtended or add a line
'FirewireGuid: 000A27....' to Device/SysInfo. You can get
your FirewireGuid by using the tests/test-fw-id test program.
* src/sha1.c
src/sha1.h
src/itdb_sha1.c
src/itdb_sha1.h
New files for obscure hash generation code.
* src/Makefile.am: added new files.
* tests/test-checksum.c
tests/test-fw-id.c
tests/Makefile.am: test programs to retrieve the
FirewireGuid and calculate/write the obscure hash.
