mesa: helper for checking renderbuffer sample count
Pulls the checking of the sample count into a helper function, and
extends the existing logic to include the interactions with both
ARB_texture_multisample and ARB_internalformat_query.
_mesa_check_sample_count() checks a desired sample count against a
a combination of target/internalformat, and returns the error enum
to be produced, if any. Unfortunately the conditions are messy and the
errors vary.
V2: - Tidy up spurious block.
- Move _mesa_check_sample_count() to multisample.c instead; It
doesn't really belong in fbobject.c or teximage.c.
- Inlined spec quotes
