initial import of nouveau kernel module core, some simple tools, and drm

Ignore (or, if you're really keen, fix) any of the horrors that are part
of the emulate-linux-on-libpciaccess (lib/) layer.  When I started down
this path I was only aiming to prototype the reworked driver core, and
never actually intended on going quite this far with things, but it turns
out that being able to develop and test the nouveau core from userspace
is *very* useful.

This tree is based on the code available as of Linux 3.8-rc2.
