i965: make BRW_COMPRESSION_2NDHALF valid for brw_SAMPLE

SIMD8 sampler messages are allowed in SIMD16 mode, and they could not work
without BRW_COMPRESSION_2NDHALF.  Later PRMs (gen5 and later) do not
explicitly state whether BRW_COMPRESSION_2NDHALF is allowed, but they do have
examples using send with SecHalf.  It should be safe to assume SecHalf is
valid.

radeon/uvd: fix video format reporting

UVD can only support NV12 in the case of hardware decoding, but we
can still use all other formats for software decoding. Use the UNKNOWN
profile to signal that we're not interesting in hardware decoding.

v2: use profile instead of entrypoint

radeon/uvd: try to fix VC-1 decoding

The DPB size calculations seem to be off; there is various random
corruption happening, even with advanced profile. Always assuming
a minimum number of references appears to fix it, similarly to
H.264. This might overallocate the DPB.  Also clean up the SPS/PPS
field setup so that it matches VC-1 specifications better.

With these changes, all advanced profile VC-1 files I could get my
hand on work fine.

radeon/uvd: disable VC-1 simple/main profile

It doesn't work (decodes to garbage) with most videos on UVD 3.0. Worse
yet, it often results in random memory corruption or GPU hangs. Rumor
has it only the newest UVD hardware could do it anyway.

gallium/state_trackers/egl: use X11_INCLUDES rather than X11_CFLAGS

The X11_CFLAGS variable is undefined (not defined in config.status).
It appears the intent was to use X11_INCLUDES defined in configure.ac.
It is used for building the code in the x11 subdir.

The build does not fail on this one as LIBDRM_CFLAGS happens to have
the inludedir value as the one for X11. It will not always be the case.
The option --enable-gallium-egl is required durimg configuration.

egl/main: remove undefined X11_LIBS automake variable

The EGL library has some references to x11 but it gets the link flags
from the XCB_DRI2_LIBS if and only if HAVE_EGL_PLATFORM_X11 is true.

The X11_LIBS variable was probably coming from a PKG_CHECK_MODULES (x11)
earlier in history.

If it is possible to have HAVE_EGL_DRIVER_GLX without HAVE_EGL_PLATFORM_X11
then the link flags for libX11 should be passed. However, it won't come
from X11_LIBS which is undefined.
