[Mesa-dev] [PATCH v3 0/4] Add support GL_ARB_texture_compression_bptc in llvmpipe and softpipe.

[Denis Pauk]

This series add code for reuse in gallium bptc decode logic from
mesa/main/texcompress_bptc.c. 

Checked on x86_64 by: 
* LIBGL_ALWAYS_SOFTWARE=true GALLIUM_DRIVER={llvmpipe,softpipe}
* piglit/bin/bptc-float-modes
* piglit/bin/bptc-modes
* piglit/bin/compressedteximage GL_COMPRESSED_RGBA_BPTC_UNORM
* piglit/bin/compressedteximage GL_COMPRESSED_SRGB_ALPHA_BPTC_UNORM
* piglit/bin/compressedteximage GL_COMPRESSED_RGB_BPTC_UNSIGNED_FLOAT
* piglit/bin/compressedteximage GL_COMPRESSED_RGB_BPTC_SIGNED_FLOAT

v2: Added logic for decompress 4x4 as single block.
v3: Move bptc decode code to texcompress_bptc_tmp.h
