* src/itdb_device.c: (itdb_device_requires_checksum):

* src/itdb_itunesdb.c: (write_db_checksum):
* src/itdb_private.h: add an itdb_device_requires_checksum function so
that we only error out because of checksum writing issues on ipods which
require a checksum. Ideally, we should restore the old file when there is
a fatal checksum writing error, but libgpod isn't currently doing that
