v3: thanks to Brian, improved coding style, also glennk helped spot few
things (unsigned -> int, two constify)

between framerate and input lag.

nine: Implement threadpool

DRI_PRIME setups have different issues due the lack of dma-buf fences
support in the drivers. For DRI3 DRI_PRIME, a race can appear, making
tearings visible, or worse showing older content than expected. Until
dma-buf fences are well supported (and by all drivers), an alternative
is to send the buffers to the server only when rendering has finished.
Since waiting the rendering has finished in the main thread has a
performance impact, this patch uses an additional thread to offload the
wait and the sending of the buffers to the server.

nv50,nvc0: handle TGSI_PROPERTY_VS_WINDOW_SPACE_POSITION

Allow viewport bypass used by D3D9 applications.
nv50,nvc0: handle NULL vertex elements without fallback

This makes Gallium Nine faster.
nv50/ir/tgsi: implement TGSI_OPCODE_NRM,DP2A

Used by d3d9 st.
hack/nv50: don't emit buffer for skipped vertex elements

Grr, should forbid that and insert dummy elements in nine.
hack/nvc0: avoid fault in get_query_result if there was no begin_query
nv50: support for hackish viewport bypass
nv50,nvc0: d3d9 requires transfer stride to be aligned to 4
gallium: add blending to pipe blit

Following nouveau commit make use of these.
