GL_SELECT hw support v3

New version !

Changelist :
- corrected the issue with GL_DEPTH_TEST : _mesa_Clear only operates in
GL_RENDER mode, so FBO depth buffer wasn't cleared
- minZ and maxZ should be correct now : the FBO is twice as height now. Top row
is drawn using GL_LESS depth function, bottom one is drawn using GL_GREATER.

I tried to build another version with custom state seup/teardown hooks to
preserve eventual user state changes but ran into massive problems. 
I'm not really sure this is a real issue though, and maybe we can just live it
with until this causes a problem in an application.
