gallium/auxiliary: implement sw_probe_wrapped (v2)

Implement pipe_loader_sw_probe_wrapped which allows to use the wrapped
software renderer backend when using the pipe loader.

v2: - remove unneeded ifdef
    - use GALLIUM_PIPE_LOADER_WINSYS_LIBS
    - check for CALLOC_STRUCT
    thanks to Emil Velikov

gallium/auxiliary: add inc and dec alternative with return (v2)

At this moment we use only zero or positive values.

v2: Implement it for also for Solaris, MSVC assembly
    and enable for other combinations.

gallium/auxiliary: add contained and rect checks (v3)

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

nine: Add state tracker nine for Direct3D9 (v2)

Work of Joakim Sindholt (zhasha) and Christoph Bumiller (chrisbmr).
DRI3 port done by Axel Davy (mannerov).

v2: - nine_debug.c: klass extended from 32 chars to 96 (for sure) by glennk
    - Nine improvements by Axel Davy (which also fixed some wine tests)
    - by Emil Velikov:
     - convert to static/shared drivers
     - Sort and cleanup the includes
     - Use AM_CPPFLAGS for the defines
     - Add the linker garbage collector
     - Restrict the exported symbols (think llvm)

nine: Add drirc options (v2)

Implements vblank_mode and throttling, which  allows us change default ratio
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.

gallium/auxiliary: Prefer intrinsics to handrolled atomic ops for Linux (v2)

v2: enable it only for Linux at this moment, where we expected it's
    build for >= i486.

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.
