As with other recent changes, put the vertex and fragment sampler state
into arrays indexed by the shader type. This will let us easily add
support for other types of shaders in the future.
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.
The previous test for result != NULL was kind of bogus since we dereferenced
the pointer earlier in the code. Now, check for result != NULL first, then
get the result->key info.
Also, remove the useless "offset +=" code at the end.
We'd end up re-using the old one and throwing away the new one anyway, but only
after a roundtrip to the kernel.

Otherwise, the wasted area could never be used for an allocation again.

If a hole exactly matches the allocated size plus alignment, we would fail to
preserve the alignment as a hole. This would result in never being able to use
the alignment area for an allocation again.

Otherwise we'll likely end up with an ever increasing amount of ever smaller
holes.
Requires keeping the list ordered wrt offsets.

Otherwise we'd wrap around after 32 bits. The kernel currently limits GPU
virtual address space to 4GB anyway, but that will probably change sooner or
later, and this would result in confusing error messages when running out of
virtual address space even now.

This adds support for having libGL pick a different driver for prime support.
DRI_PRIME env var is set to the value retrieved from the server randr
provider calls, by the calling process. (generally DRI_PRIME=1 will be
the right answer).

With this we can embed data for the shaders (like resource
descriptors) into the PM4 stream.

I was seeing some GPU hangs that seemed to be cause by ALU instructions
writing to the same register used as the source for VTX_READ. Adding
this constraint to the VTX_READ instructions avoids this situation.
