st/nine: Protect dtors with mutex
When the flag D3DCREATE_MULTITHREAD is set, a global mutex is used
to protect nine calls.
However for performance reasons, AddRef and Release didn't hold the mutex,
and instead used atomics.
Unfortunately at item release, the item can be destroyed, and that
destruction path should be protected by a mutex (at least for
some objects).
Without this patch, it is possible an app thread is in a dtor
while another thread is making gallium nine calls. It is possible
that two threads are using the same gallium pipe, which is forbiden.
The problem has been made worse with csmt, because it can cause hang,
since nine_csmt_process is not threadsafe.
Fixes Hitman hang, and possibly others.

st/nine: Align stack for entry points
For 32 bits, incoming stack is 4-byte aligned.
We need to realign the stack to 16-byte at some point,
or there are issues later (crash with SSE, llvm, etc).
This patch chooses to align the stack at API entry points.

nine: Add state tracker nine for Direct3D9 (v3)
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)
v3: - small nine fixes
- build system improvements by Emil Velikov
v4: [Emil Velikov]
- Do no link against libudev. No longer needed.
