merge xorg-server 1.20.3.

first merge of netbsd changes. not tested yet.

we've been happily using bsdPciInit since xorg was first imported.
remove local changes that were only relevant in the xfree86 days.

merge cornflakes with xorg-server 1.10.3

merge xorg-server 1.9.2.

merge xorg-server 1.6.1.190.

XXX: our Pci.[ch] changes need to be re-looked at, i think.

add missing bits & pieces for sparc(64) and Sbus support
While there, use ppc_video.c on sparc(64) as well, sparc64_vodeo.c is
almost identical and only misses EnableIO() stuff which we'll want to add
at some point anyway and then they'd be identlical to the ones from
ppc_video.c anyway.

add sparc64 goo, from xsrc/xfree

attempt to support netbsd/arm

initial import of xorg-server-1.4.2
