hw support for GL_SELECT v2

Here's a new version of the patch :
- I've simplified it a bit (removed the fragment program)
- corrected a few bugs (no more crash=
- tried to improve performance by batching query/readback

It only works with Gallium-based drivers (and breaks GL_SELECT on non-Gallium
drivers), but that should be easy to fix.

I'd appreciate some testing by other users to confirm that it's working (and is
faster than the current implementation).
