Failing x11/xf86-video-* driver compiles

[Robert Elz <kre%munnari.OZ.AU@localhost>]

After the recent modular-xorg-server update, about half of the xf86-video
driver packages no longer compile.   As I understand what happened, most
of those weren't touched, beyond a revbump, so the compilation errors
must result from a changed environment provided by the different server
version.

Do you want PR's on all the ones I know about?   The most common errors
seem to derive from missing include files, but there are others like
missing fields from structures, and "missing binary operator before '('"
and similar...

The ones that compiled for me earlier, but no longer compile now, are:

xf86-video-chips
xf86-video-cyrix
xf86-video-glint
xf86-video-imstt
xf86-video-neomagic
xf86-video-nsc
xf86-video-rendition
xf86-video-s3
xf86-video-siliconmotion
xf86-video-sis
xf86-video-tdfx
xf86-video-tga
xf86-video-trident
xf86-video-tseng
xf86-video-vga
xf86-video-via
xf86-video-wsfb

Of those, I'd guess the most significant problem is xf86-video-vga
most of the rest seem to be drivers for chipsets that are probably
not all that frequently encountereed these days.

I'm compiling these in a NetBSD 4 environment (obtained via pkg_comp
with libkver and  4.0 release sets (excluding X) instealled) - but
that probably makes no difference, as all this stuff compiled in the
same environment with the previous version of modular-xorg-server.

If needed I can send in PR's with the individual compile errors
I'm getting, but my guess is that anyone who might have some idea
how to fix this (which isn't me) can just as easily compile the
things themselves (and would want to to confirm anyway).
