	* 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.
