This adds support to gallium for a TG4 instruction,
and two CAPs. The first CAP is required for GL_ARB_texture_gather.
The second CAP is required to expose GL_ARB_gpu_shader5.
However so far we haven't found any hardware that natively
exposes the textureGatherOffsets feature from GL, so just
lower it for now. If hardware appears for this we can add
another CAP to allow TG4 to take 4 offsets.
v2: add component selection src and a cap to say
hw can do it. (st can use to help control
GL_ARB_gpu_shader5/GLSL 4.00). Add docs.
v3: rename to SM5, add docs.

This patches add MESA_copy_sub_buffer support to the dri sw loader and
then to gallium state tracker, llvmpipe, softpipe and other bits.
It reuses the dri1 driver extension interface, and it updates the swrast
loader interface for a new putimage which can take a stride.
I've tested this with gnome-shell with a cogl hacked to reenable sub copies
for llvmpipe and the one piglit test.
I could probably split this patch up as well.
v2: pass a pipe_box, to reduce the entrypoints, as per Jose's review,
add to p_screen doc comments.
v3: finish off winsys interfaces, add swrast classic support as well.

swrast: add support for copy_sub_buffer
Ever since introducing separate sampler and sampler view max this was really
missing.
Every driver but llvmpipe reports the same number as number of samplers for
now, so nothing should break.

This is the only sane solution for nv50 and nvc0 (really, trust me),
but since on other hardware the border colour is tightly coupled with
texture state they'd have to undo the swizzle, so I've added a cap.
The dependency of update_sampler on the texture updates was
introduced to avoid doing the apply_depthmode to the swizzle twice.
v2: Moved swizzling helper to u_format.c, extended the CAP to
provide more accurate information.
This is a basic implementation of the pipeline statistics in the
draw module. The interface is similar to the stream output statistics
and also requires that the callers explicitly enable it.
Included is the implementation of the interface in llvmpipe and
softpipe. Only softpipe enables the pipeline statistics capability
though because llvmpipe is lacking gathering of the fragment shading
and rasterization statistics.

This makes it possible to identify gl_TexCoord and gl_PointCoord
for drivers where sprite coordinate replacement is restricted.
The new PIPE_CAP_TGSI_TEXCOORD decides whether these varyings
should be hidden behind the GENERIC semantic or not.
With this patch only nvc0 and nv30 will request that they be used.
v2: introduce a CAP so other drivers don't have to bother with
the new semantic
v3: adapt to introduction gl_varying_slot enum
This adds support to draw for the new features of transform feedback.
a) fix count_from_stream_output, using max_index+1 for now but it looks
like it should be valid as its derived from the vertex elements/vbo.
b) fix striding and dst offsets in output buffers - was just wrong before.
c) fix crash if tfb is suspended (so.num_targets == 0)
This also enables the new features on softpipe. It should be possible
to enable them on llvmpipe as well after this commit, but would need
to schedule piglit runs.

The corner case averaging is messy but seems like it should be spec
compliant.
The face direction stuff is also a bit messy, I've no idea if that could

PIPE_MAX_SAMPLERS, PIPE_MAX_VERTEX_SAMPLERS and PIPE_MAX_GEOMETRY_SAMPLERS
were all defined to the same value (16).
In various places we're creating arrays such as
sampler_views[PIPE_SHADER_TYPES][PIPE_MAX_SAMPLERS] so we were assuming
the same number of max samplers for all shader stages anyway.
Of course, drivers are still free to advertise different numbers of max
samplers for different shaders.
- Use LLVM limits when LLVM is being used, instead of TGSI limits
- Provide draw_get_shader_param_no_llvm for when llvm is never used (softpipe)
- Eliminate several of the hacks around draw shader caps in several drivers
Unfortunately the hack for PIPE_MAX_VERTEX_SAMPLERS is still necessary.
