utils: fix build with <GL/glext.h> version >= 85.

Mesa recently updated the <GL/glext.h> header version to Khronos version 85.
This caused the PFNGLMULTITEXCOORD2FPROC definition to be moved out of the
GL_VERSION_1_3_DEPRECATED block. However, since <GL/gl.h> also defines
GL_VERSION_1_3 to 1, the definitions in <GL/glext.h> are then not enabled,

h264: fix slice_data_bit_offset calculation.

Unlike what VA-API documentation defines, the slice_data_bit_offset
represents the offset to the first macroblock in the slice data, minus
any emulation prevention bytes in the slice_header().

This fix copes with binary-only VA drivers that won't be fixed any
time soon. Besides, this aligns with the current FFmpeg behaviour
that was based on those proprietary drivers implementing the API
incorrectly.

decoder: fix double buffer free with some VA drivers.

vaRenderPicture() implicitly disposes VA buffers. Some VA drivers would
push the VA buffer object into a list of free buffers to be re-used. However,
reference pictures (and data) that was kept would explicitly release the VA
buffer object later on, thus possibly destroying a valid (re-used) object.

Besides, some other VA drivers don't support correctly the vaRenderPicture()
semantics for VA buffers disposal and would leak memory if there is no explicit
vaDestroyBuffer(). The temporary workaround is to explcitily destroy VA buffers
right after vaRenderPicture(). All VA drivers need to be aligned.
