If the SVGA3D_BindGBSurface() call in svga_buffer_hw_storage_unmap()
fails, we'll flush and that might involve unmapping other buffers.
That leads to a recursive lock on svga_screen::swc_mutex and causes
a deadlock.  Fix this by initializing the mutex with mtx_recursive.

Note that this only happened on Linux, not Windows.  On Windows, the
mutex functions are implemented with Win32 critical sections which

However, we have enough custom flag settings floating around the driver

following functional changes:

 1) The workaround_bo created in anv_CreateDevice loses both flags.
    This shouldn't matter because it's very small and entirely internal
    to the driver.

 2) The bo created in anv_CreateDmaBufImageINTEL loses the

mesa: Remove GL_APPLE_vertex_array_object stubs

Mark the functions 'exec="skip"' in the XML instead.  libGL will still
have the functions, but the driver won't try to use them.  I verified
that this commit works with piglit's 'object-namespace-pollution glClear
vertex-array' on x64 with a driver built from mesa-12.0.3 tag.

In fairness, this test also works with a libGL built from 7927d03.  I
believe it continues to work because on non-Windows platforms we
generate some extra, dummy dispatch functions that can be used when a
driver requests a function unknown to libGL.  This was done to provide
some "forward" compatibility with drivers that need more functions.
This doesn't work on Windows because the Windows calling convention is
for the callee to clean up the stack.  That's the theory anyway.

radv: Add compute HTILE fast clear.

Not really what the fast depth clear does, no matter whether you use
EXPCLEAR or not. Seems the fast clear using the DB HW always touches
the main buffer.

radv: Use correct clear words for HTILE.

Did some RE'ing what several HTILE words give when read from a descriptor
with HTILE compression enabled.

Seems to align with -pro usage for D16 too.

Potentially more efficient as it may avoid the struct being initialised
twice.

ralloc: Use strnlen() inside of strncat()

If the str is long or isn't null-terminated, strlen() could take a lot
of time or even crash. I don't know why was it used in the first place,
maybe for platforms without strnlen(), but strnlen() is already used
inside of ralloc_strndup(), so this change should not additionally
break anything.
