Bruce Evans 6f5014b462 Convert to ANSI C: change #endif THING to #endif /* THING */.
Fix one such THING in code to match comment.
Sort IO_GSC* into numeric order and update comments about the gaps.
Sort common SCSI addresses into alphabetical order.
Remove bogus comments about com ports having i/o size 4.
Uniformize whitespace.
Uniformize case in hex digits.

This file is very incomplete.  In particular, it doesn't mention any
network cards.  This doesn't matter much for the base addresses, but
it means that the comments about which addresses are free are mostly
bogus.  The i/o sizes are unreliable because of split address ranges
for many devices (VGA, wd).  The i/o sizes are incomplete.  In
particular, there are no sizes for SCSI controllers.  The bt driver
still returns a truth value instead of a size.
