Start each of the license/copyright comments with /*-, minor shuffle of lines

Update copyright info, and make some slight cosmetic changes.

Update include directives for Linuxulator headers after the
MD/MI split.

Studied the tech docs for the Voodoo3 and Banshee, and hopefully fixed the
errors that plagued those cards with XFree86 4.0. They have two memory
ranges as well as an IO port range to them. Also cleaned up the three
warning messages that I got, from inb(), outb() and linuxulator. Also, I
noticed that the DRI and Glide support for the Voodoo4 and 5 has been
placed upon linux.3dfx.com, too bad they haven't released the tech docs
yet. Apparently, they are still pushing glide for all of us, so I will try
and add support once those tech docs are up.

Stupid me, I put the opt_tdfx.h underneath a test for TDFX_LINUX, which
resides in opt_tdfx. I also cleand up that large define. Compile, tell me
if it does, and I'll re-enable the tdfx entry in the makefile.

Fixed problem with linux ioctl code, module loading should work now.
