swr: Don't crash when encountering a VBO with stride = 0.

possible for VBO's with stride=0. This resulted in a divide by zero

egl/display: make platform detection thread-safe

Imagine there are 2 threads that both call _eglGetNativePlatform()
simultaneously:
- thread 1 completes the first "if (native_platform ==
  _EGL_INVALID_PLATFORM)" check and is preempted to do something else
- thread 2 executes the whole function, does "native_platform =
  _EGL_NATIVE_PLATFORM" and just before returning it's preempted
- thread 1 wakes up and calls _eglGetNativePlatformFromEnv() which
  returns _EGL_INVALID_PLATFORM because no env vars are set, updates
  native_platform and then gets preempted again
- thread 2 wakes up and returns wrong _EGL_INVALID_PLATFORM

Solve this by doing the detection in a local var and only overwriting
the global one at the end, if no other thread has updated it since.

This means the platform detected in the thread might not be the platform
returned by the function, but this is a different issue that will need
to be discussed when this becomes possible.

svga: Rework the blit and resource_copy_region functionality v3

This work was initially trigged by the fact that imported surfaces may
be backed by other SVGA3D formats than the default. Therefore some fixes were
needed to avoid using the copy_region_vgpu10() functionality for incompatible
SVGA3D formats where the pipe formats were OK. This situation happens when
using dri3.

Also in some situations, for example where a R8G8_UNORM surface is backed by
an SVGA3D_NV12 format, we can't use the copy_region functionality at all and
thus need to fall back to the quad blitter also for the resource_copy_region
function. This situation doesn't happen currently, but will if we start using
video textures.

The patch makes the blit- and copy_region paths similar and the decision whether
to use a certain gpu command should now be easy to locate. Probably the
resource_copy_region path will suffer from a minor additional cpu overhead,
but on the other hand there are more cases now that we accelerate, since
we try harder before falling back to cpu copies / blits.

v2: Addressed review comments and fixed up piglit failures by sometimes
preferring cpu_copy_region() over blit().
v3: Removed a stray test statement. Updated commit message.

i965: Improve conditional rendering in fallback paths.

We need to fall back in a couple of cases:
- Sandybridge (it just doesn't do this in hardware)
- Occlusion queries on Gen7-7.5 with command parser version < 2
- Transform feedback overflow queries on Gen7, or on Gen7.5 with
  command parser version < 7

In these cases, we printed a perf_debug message and fell back to
_mesa_check_conditional_render(), which stalls until the full
query result is available.  Additionally, the code to handle this
was a bit of a mess.

We can do better by using our normal conditional rendering code,
and setting a new state, BRW_PREDICATE_STATE_STALL_FOR_QUERY, when
we would have set BRW_PREDICATE_STATE_USE_BIT.  Only if that state
is set do we perf_debug and potentially stall.  This means we avoid
stalls when we have a partial query result (i.e. we know it's > 0,
but don't have the full value).  The perf_debug should trigger less
often as well.

Still, this is primarily intended as a cleanup.
