i965: Add driconf option clamp_max_samples
The new option clamps GL_MAX_SAMPLES to a hardware-supported MSAA mode.
If negative, then no clamping occurs.
v2: (for Paul)
- Add option to i965 only, not to all DRI drivers.
- Do not realy on int->uint cast to convert negative
values to large positive values. Explicitly check for
clamp_max_samples < 0.
v3: (for Ken)
- Don't allow clamp_max_samples to alter context version.
- Use clearer for-loop and correct comment.
- Rename variables.
v4: (for Ken)
- Merge identical if-branches.
