We always mapped the query buffer in begin_query, causing stalls
if the buffer was busy.
This commit reworks it such that the query buffer is only mapped
in get_query_result as it's supposed to be.
The query buffer is no longer treated as a ring buffer. Instead, the results
are just appended and when the buffer is full, we create a new one. One query
can have more than one query buffer, though that's a very rare case.
Begin_query releases all query buffers.

This fixes another case of faulting when freeing a pipe_sampler_view

Basically, instead of immediately freeing deleted surfaces, hang onto
them in a cache to do quick re-allocation. This helps when surfaces
are frequently destroyed and then reallocated a bit later.

There was a SVGA_HOST_SURFACE_CACHE_BYTES symbol, but it was never
used.
Now when we go to add a newly deleted surface to the cache we check
if the cache size would be exceeded. If so, try to free the least
recently "unused" surfaces until the cache is smaller. If we can't
do that, simply don't cache the newly deleted surface. The alternative
involves flushing and waiting and we don't want to do that.

Before, if shader translation failed for any reason we'd keep trying
to translate the shader over and over again during state validation.
The dummy fragment shader emits solid red so that might be visual
clue that translation is failing.

The assertion recently added in dst_register() was invalid because that
function is also (suprisingly) used to declare constant registers.
Move the assertion to the callers where we're really creating temp
registers and add some code to prevent emitting invalid temp register
indexes for release builds.
Also, update the comment for get_temp(). It didn't return -1 if it
ran out of registers and none of the callers checked for that.

Commit 980f6f1 (mesa: move gl_texture_image::Width/Height/DepthScale
fields to swrast) moved the initialization of the Width, Height, and
DepthScale fields to _swrast_alloc_texture_image_buffer(). However,
i915 doesn't call this function because it performs its own buffer
allocation. As a result, the Width, Height, and DepthScale fields
weren't getting initialized properly, and some operations requiring
swrast would fail.
This patch ensures that Width, Height, and DepthScale are properly
initialized by separating the code that sets them into a new function,
_swrast_init_texture_image(), which is called by
intel_alloc_texture_image_buffer() as well as
_swrast_alloc_texture_image_buffer(). It also moves the
initialization of _IsPowerOfTwo into this function.
Fixes piglit test fbo/fbo-cubemap on i915.
Partially fixes https://bugs.freedesktop.org/show_bug.cgi?id=41216

GBM needs the buffer format in order to communicate with DRM and clients
for things like scanout.
So track the DRI format requested in the various back ends and use it to
return the DRI format back to GBM when requested. GBM will then map
this into the GBM surface type (which is in turn based on the DRM fb
format list).
