When a buffer invalidation event is received from the X server, the
"invalidate" hook of the DRI2 flush extension is executed: A generic
implementation (dri2InvalidateDrawable) is provided that just bumps
the "pStamp" sequence number in __DRIdrawableRec.
For old servers not supporting buffer invalidation events, the
invalidate hook will be called before flushing the fake front/back
buffer (that's typically once per frame -- not a lot worse than the
situation we were in before).
No effort has been made on preserving backwards compatibility with
version 2 of the flush extension, but I think it's acceptable because
AFAIK no released stack is making use of it.

(cherry picked from commit 3094adb3ca)
My first reading of MS docs was wrong. It says:
All rendering contexts of a shared display list must use an identical
pixel format. Otherwise the results depend on the implementation of
OpenGL used.
That is, it is OK to share contexts with different pixel formats.
Adobe Premiere Pro tries to do that: share lists between a rgbx8 and a
rgba8 pixel format.
Gallium interfaces are too fluid -- XML or not is just too much work
trying to accommodate for differences in traces.
SWIG generated bindings are also full of quirks, making unmarshalling
the XML from too hard.
Finally, this is the first step for faster tracing.
__builtin_clz with parameter 0 has undefined value. When
using -O3 optimizing this would result to too large next
power of two value.
Fix is to check if passed value is 1 and modify formula
for that case.
MACRO_SWITCH is applied to samplers but not renderbuffers. This commit
fixes incorrect rendering to large and small mipmaps where the large ones
are macrotiled and the small ones are not and both are emitted
in the same CS.
Note that this is still disabled by default (rework of texture transfers
is next).
