Great work Eric :)

A couple of trivial ones (apart from patch 8 and 13)

* IMHO you safely drop "dridir" from nouveau, radeon, r200, i915 's
Makefile.am. It's already set in src/mesa/drivers/dri/Makefile.am

* Can you please leave a comment in code, wrt the i915/radeon header
reshuffle ?

As a follow up to a question from XDC, size of st/dri wrt the driver
itself here are some numbers that give can give you a rough idea.

[ 25M]  libnouveau.a
[ 52K]  libnouveaudrm.a
[408K]  librbug.a

Initially I got over-exited over the idea until I realized that gallium
does not use/build libdricore :)

I'm planning to have something by the end of the week (just got my final
year project at Uni), although my plan is to leave it optional. Any
suggestions/preferences ?
