intel: Assert that no batch is emitted if a region is mapped

What I would prefer to assert is that, for each region that is currently
mapped, no batch is emitted that uses that region's bo. However, it's much
easier to implement this big hammer.

Observe that this requires that the batch flush in intel_region_map() be
moved to within the map_refcount guard.

mesa: add packing for int/uint

This just adds a simple packing for GL_UNSIGNED_INT/GL_INT destination formats.
This is enough for at least the gallium drivers to pack both unsigned and signed types for read pixels.

u_format: add inline helper to find first non void channel

This is used in a few places in drivers as well, also the integer support
can use it as well.

i965: Fix inconsistent indentation in brw_eu_emit.c.

Most of these functions used three spaces for the first level of
indentation, but four spaces for the next level.  One used tabs and then
three spaces.  Some used 3/4 in a then block but 3/3 in the else block.

Normally I try to avoid field days like this, but since the functions
were so inconsistent, even internally, it was making it difficult to
edit without introducing spurious whitespace changes.

So, just get it over with.  git diff -b shows 0 lines changed.
