This patch add support to gzip'ed database files to usb-db.c and add

Looking at the code it seems that enabling zlib support sets HAVE_ZLIB
which assumes that the DBs are always compressed with gzip which removes
the support for uncompressed db files. Logically, both should be
supported with some kind of file format detection.
zlib functions can read compressed and uncompressed files. That's why I
try to
open DATABASE.gz first and, if failed, open DATABASE when zlib support is
enabled. The support of both file formats is OK when zlib is enabled.
When disabled, only uncompressed files are supported. Almost no changes
there. The only drawback of enable zlib support is the need of zlib shared
library. But, who are using gzip'ed ID db files already needs zlib to have
working lsusb and lspci.
Ignore this if I wrongly understand the intention :)
Oh, i think is better to explain. Maybe someone else have the same doubt.
Hope it's all OK now -:)
