[Mesa-dev] i965/meta: Bypass core vertex buffer setup

[Topi Pohjolainen]

This series introduces custom pipeline state upload for fast, rep
and resolve clears. For now only vertex buffer and vertex fetcher
state uploads are overrided. The base mechanism, however, makes it
possible to reduce the dependence to core context gradually by one
atom at a time if desired.
I tried a few approaches, and I selected this as it was the least
intrusive and didn't regress any synthetic benchmarks.

During the development of render buffer compression I discovered
corner cases that out current driver internal context save/restore
mechanism couldn't support. I tried fixing it but just discovered
more corner cases to consider. I worked on blorp+meta in the past
and decided to try one more time if I could break the dependence
of meta operations from core context.

The last patch in the series is not critical, it is just something
I wrote on the way.
