[Mesa-dev] [PATCH] RFC: refactor out dri2 proto code into libdri2

Since I was working on some extensions to DRI2 protocol for handling
video, it occurred to me that it might be easier to extend the
protocol if there weren't N different copies of dri2.c floating around
in various different src trees.. also, for video, with one or two
other small extensions (ie. standard way to mmap() GEM buffers), I
think it should eventually be possible for DRI2 to be directly used
by end applications (ie. for sw video decoders, etc). So refactoring
this out into a shared library pretty much seemed like the right-
thing-to-do.
This patch updates mesa to remove two nearly identical copies of DRI2
protocol code. The error, wire->event, and event->wire stuff is split
out into some callbacks, as this was really the only differences
between the two copies of dri2.c (and also, other than name changes,
the main difference between what is in mesa and vaapi). Also, from
looking at the git history, it appears that these callbacks are the
main place where there have been any changes to this code in the last
couple years.
Temporary home for libdri2 tree is here:
git://people.freedesktop.org/~robclark/libdri2
Eventually I can make patches for libva and libvdpau.. but I started
with mesa because that was something I actually had a way to test.
