svga: flush buffers when mapping for reading

With host-side buffer copies (via SVGA3D_vgpu10_BufferCopy()) we have
to make sure any pending map-write operations are completed before reading
if the buffer is dirty.  Otherwise the ReadbackSubResource operation could
get stale data from the host buffer.

This allows the piglit arb_copy_buffer-subdata-sync test to pass when

gallium/radeon: add a heuristic enabling DCC for scanout surfaces (v2)

DCC for displayable surfaces is allocated in a separate buffer and is
enabled or disabled based on PS invocations from 2 frames ago (to let
queries go idle) and the number of slow clears from the current frame.

At least an equivalent of 5 fullscreen draws or slow clears must be done
to enable DCC. (PS invocations / (width * height) + num_slow_clears >= 5)

Pipeline statistic queries are always active if a color buffer that can
have separate DCC is bound, even if separate DCC is disabled. That means
the window color buffer is always monitored and DCC is enabled only when
the situation is right.

The tracking of per-texture queries in r600_common_context is quite ugly,
but I don't see a better way.

The first fast clear always enables DCC. DCC decompression can disable it.
A later fast clear can enable it again. Enable/disable typically happens
only once per frame.

The impact is expected to be negligible because games usually don't have
a high level of overdraw. DCC usually activates when too much blending
is happening (smoke rendering) or when testing glClear performance and
CMASK isn't supported (Stoney).

st/omx: fix decoder fillout for the OMX result buffer

The call for vl_video_buffer_adjust_size is with wrong order of
arguments, apparently it will have problem when interlaced false;

The size of OMX result buffer depends on real size of clips, vl buffer
dimension is aligned with 16, so 1080p(1920*1080) video will overflow

i965: Make emit_urb_writes() not produce an EOT message for GS.

emit_urb_writes() contains code to emit an EOT write with no actual
data when there are no output varyings.  This makes sense for the VS
and TES stages, where it's called once at the end of the program.

However, in the geometry shader stage, emit_urb_writes() is called once
for every EmitVertex().  We explicitly emit a URB write with EOT set at
the end of the shader, separately from this path.  So we'd better not
terminate the thread.  This could get us into trouble for shaders which
do EmitVertex() with no varyings followed by SSBO/image/atomic writes.

It also caused us to emit multiple sends with EOT set, which apparently
confuses the register allocator into not using g112-g127 for all but
the first one.  This caused EU validation failures in OglGSCloth
shaders in shader-db.  (The actual application was fine, but shader-db
thinks there are no outputs because it doesn't understand transform
feedback.)
