[RFC PATCH 0/9] Bus layer cleanups

[Adam Jackson]

This attempts to tackle Tiago's (justified) hatred for the IOADDRESS type
in a slightly more elegant way.  We move more of the VGA hacks to vgahw,
port it and int10 over to pciaccess' legacy I/O API, and then clean up
some of the remaining detritus.

THIS IS AN ABI BREAK.  Like, a pretty massive one.  Please do not pull
this yet.  I'm mostly looking for r-b's here that the strategy looks
sane.  The driver work needs to land before this lands, and it's pretty
trivial, but I don't want to bother unless this is actually going to
merge.

Once (if) this lands, the only remaining direct usage of {in,out}[bwl]
in xserver will be xf86SlowBcopy (jokes).  This also makes it plausible
to convert the rest of the drivers to the pciaccess API, which then
means we can drop roughly 137% of the content of compiler.h.
