i965: Implement transform feedback query support in hardware on Gen6+.
Now that we have hardware contexts and can use MI_STORE_REGISTER_MEM,
we can use the GPU's pipeline statistics counters rather than going out
of our way to count primitives in software.
Aside from being simpler, this also paves the way for Geometry Shaders,
which can output an arbitrary number of primitives on the GPU. It will
also allow us to use hardware primitive restart when these queries are
in use.
The GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN query is easy: it
corresponds to the SO_NUM_PRIMS_WRITTEN/SO_NUM_PRIMS_WRITTEN0_IVB
counters.
The GL_PRIMITIVES_GENERATED query is trickier. Gen provides several
statistics registers which /almost/ match the semantics required:
- IA_PRIMITIVES_COUNT
The number of primitives fetched by the VF or IA (input assembler).
This undercounts when GS is enabled, as it can output many primitives.
- GS_PRIMITIVES_COUNT
The number of primitives output by the GS. Unfortunately, this
doesn't increment unless the GS unit is actually enabled, and it
usually isn't.
- SO_PRIM_STORAGE_NEEDED*_IVB
The amount of space needed to write primitives output by transform
feedback. These naturally only work when transform feedback is on.
We'd also have to add the counters for all four streams.
- CL_INVOCATION_COUNT
The number of primitives processed by the clipper. This doesn't work
if the GS or SOL throw away primitives for rasterizer discard.
However, it does increment even if the clipper is in REJECT_ALL mode.
Dynamically switching between counters would be painfully complicated,
especially since GS, rasterizer discard, and transform feedback can all
be switched on and off repeatedly during a single query.
The most usable counter is CL_INVOCATION_COUNT. The previous two
patches reworked rasterizer discard support so that all primitives hit
the clipper, making this work.

By setting the clipper to REJECT_ALL mode, all primitives get thrown away,
so rendering is still appropriately disabled.
This may negatively impact performance in the rasterizer discard case,

intel: Don't spam "intelReadPixels: fallback to swrast" in non-PBO case.
When an application is using PBOs, we attempt to use the BLT engine to
perform ReadPixels. If that fails due to some restrictions, it's useful
to raise a performance warning.
In the non-PBO case, we always use a CPU mapping since getting the data
into client memory requires a CPU-side copy. This is a very common case,
so raising a performance warning is annoying. In particular, apitrace's
image dumping code hits this path, causing it to print hundreds of
thousands of performance warnings via ARB_debug_output. This tends to
obscure actual errors or other important messages.

intel: Do a depth resolve before copying images between miptrees.
When intel_finalize_mipmap_tree() calls intel_miptree_copy_teximage()
to reassemble a depth miptree that has been broken apart into pieces
(to deal with misalignment of levels/layers within the miptree), it
just copies the depth data, not the HiZ data. This is reasonable,
since the alignment restrictions of HiZ are a large part of the reason
why the miptree had to be broken apart in the first place. However,
in order for the depth copy to be sufficient, we need to do a depth
resolve first, to make sure any deferred depth writes that are in the
HiZ buffer get performed.

st/mesa: handle texture_from_pixmap and other surface-based textures correctly
There were 2 issues with it:
1) The texture format which should be used for texturing was only set
in gl_texture_image::TexFormat, which wasn't used for sampler views.
2) Textures are sometimes reallocated under some circumstances
in st_finalize_texture, which is unacceptable if the texture comes
from a window system.
The issues are resolved as follows:
1) If surface_based is true (texture_from_pixmap, etc.), store the format
in a new variable st_texture_object::surface_format.
2) Don't reallocate a surface-based texture in st_finalize_texture.
Also don't use st_ChooseTextureFormat is st_context_teximage, because
the format is dictated by the caller.
This fixes the glx-tfp piglit test.
