Build fixes for 2.5.x, thank Gregoire Favre <greg@ulima.unil.ch>

for pointing out these flaws regularly...

Changes in detail:

- added comapt.[ch] again, but removed the *_usercopy() crap. We
define dvb_usercopy() until generic_usercopy() is available.
If you have an external source tree, please check what's actually
needed to get your application to compile and report back to me
or on the mailing list. Thanks!
(Necessary changes to the Makefile, and various dvb files, removed some
unnecessary #include <linux/videodev>)

- added linux/lib/Makefile. We need to add an include to
drivers/media/dvb/dvb-core/Makefile.lib, so that crc32.o
gets build automagically
(Adjusted the "makelinks" script as well)
