This change releases the stw_framebuffer::mutex past creation of
the pbuffer stw_framebuffer. Without this change the pbuffers
lock is never released. Since on win32 mutexes are recursive, this
does not hurt as long as all actions on a context are done from
the same thread. But if, for example, context creation happens in
a different thread than usage, every access to the context will
block for ever.

In commit 018ea68d87, when I
de-compacted clip planes on Gen6+, I updated both the old and new VS
back-ends to reflect the change in how clip planes are stored, but I
failed to change the code in gen6_vs_state.c that uploads clip plane
constants when using the old VS back-end.
As a result, if the set of enabled clip planes wasn't contiguous
starting with 0, then clipping would not occur properly. This patch
corrects gen6_vs_state.c to upload clip plane constants in the new
de-compacted form.
This only affects the old VS back-end (which is used for
fixed-function and ARB vertex programs, not for GLSL vertex shaders).
Fixes Piglit test fixed-clip-enables.

This fixes a bug where we'd wind up emitting an invalid instruction like
MOVE R[0]., R[1]; - note the empty/zero writemask. If we don't write to
any dest register channels, cull the instruction.
v2: simply change/fix the existing test for instruction culling.
Instead of the renderbuffer pointer. In the future, attaching a texture
may not mean the renderbuffer pointer gets set too.
Plus, remove some commented-out assertions.
v2: add a 'reading' parameter to distinguish between reading and writing
to the renderbuffer (we don't want to check if _ColorReadBuffer is null
when we're about to draw). Eric found this mistake.
These functions were only called in framebuffer.c where they were defined.
Remove the unneeded attIndex parameter too.

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.
v2: Add comments (borrowed from anholt's reply) explaining why the
assertion is a good idea.

When updating a register reference to reflect the fact that we were
taking its absolute value, the fragment shader back-end failed to
clear the negate flag, resulting in abs(-x) getting computed as
-abs(x).
I also found (and fixed) a similar problem in brw_eu.h, but I'm not
aware of an actual manifestation of that problem.
Fixes piglit test glsl-fs-abs-neg-with-intermediate.
brw_set_compression_control took a GLboolean as an argument, then
promptly used a switch statement to compare it with various enumeration
values. Clearly it's not actually a boolean.
Introduce a new enumeration type, enum brw_compression, and use that.
Found by converting GLboolean to bool; clang then gave warnings about
switching on a boolean and ultimately duplicated case errors.

Previously it was getting set in draw_set_mapped_constant_buffer() but
if there were no shader constants, that function wasn't called. So the

Instead of 12 use DRAW_TOTAL_CLIP_PLANES. The max number of user-defined

For example, GL_TRIANLGES is converted to _3DPRIM_TRILIST.
The conversion is necessary because HiZ and MSAA resolve operations emit
a 3DPRIM_RECTLIST, which cannot be conveyed by GLenum.
As a consequence, brw_gs_prog_key.primitive is also converted.
