freedreno: threaded batch flush

Graphics / Mesa 3D Graphics Library / Mesa - Rob Clark [gmail.com] - 30 July 2016 08:23 UTC

With the state accessed from GMEM+submit factored out of fd_context and into fd_batch, now it is possible to punt this off to a helper thread. And more importantly, since there are cases where one context might force the batch-cache to flush another context's batches (ie. when there are too many in-flight batches), using a per-context helper thread keeps
various different flushes for a given context serialized.

TODO as with batch-cache, there are a few places where we'll need a mutex to protect critical sections, which is completely missing at the moment.
