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.

The linked list of memory allocations was not protected by a mutex.
This lead to sporadic failures with multi-threaded apps.

This fixes another case of faulting when freeing a pipe_sampler_view
that belongs to a previously destroyed context.

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.
