Move shared bptc functions to texcompress_bptc_tmp.h:
* fetch_rgba_unorm_from_block
* fetch_rgb_float_from_block
* compress_rgba_unorm
* compress_rgb_float
Create decompress functions:
* decompress_rgba_unorm
* decompress_rgb_float
Functions will be reused in gallium/auxiliary code.
v2: Add block decompress function
v3: Move all shared code to header

Various pieces of code to create compressed textures will first
generate an uncompressed RGBA texture into a temporary buffer,
and then read from that buffer while creating the final compressed
texture in the requested format.
The code reading from the temporary buffer assumes the buffer is
formatted as an array of bytes in RGBA order. However, the buffer
is filled using a _mesa_texstore call with MESA_FORMAT_R8G8B8A8_UNORM
format -- this is defined as an array of *integers* holding the
RGBA values in packed format (least-significant to most-significant).
This means incorrect bytes are accessed on big-endian systems.
This patch fixes this by using the MESA_FORMAT_A8B8G8R8_UNORM format
instead on big-endian systems when filling the buffer. This fixes
about 100 piglit test case failures on s390x for me.

Now that we have _mesa_format_convert we don't need this.
This was only used to create temporary RGBA float images in the process
of storing some compressed formats. These can call _mesa_texstore
with a RGBA/float dst to achieve the same goal.

Now that we have _mesa_format_convert we don't need this.
texstore_rgba will use the GL_COLOR_INDEX to RGBA conversion
helpers instead and compressed formats that used
_mesa_make_temp_ubyte_image to create an ubyte RGBA temporary
image can call _mesa_texstore with a RGBA/ubyte dst to
achieve the same goal.

This adds compressors for all four of the BPTC compressed-texture formats. The
compressor is written from scratch and takes a very simple approach. It always
uses a single mode of the BPTC format (4 for unorm and 3 for half-floats) and
picks the two endpoints by dividing the texels into those which have more or
less than the average luminance of the block and then calculating an average
color of the texels within each division.
It's probably not really sensible to try to use BPTC compression at runtime
because for example with the Nvidia offline compression tool it can take in
the order of an hour to compress a full-screen image. With that in mind I
don't think it's worth having a proper compressor in Mesa and this approach
gives reasonable results for a usage that is basically a corner case.
v2: Always use the custom compressor, even for the unorm formats. Fix the
quantization step for the half-float format compressor. Fixed a typo which
was breaking the right-hand edge of half-float textures with a width that
isn't a multiple of four.

Adds functions to fetch from any of the four BPTC-compressed formats.
v2: Set the alpha component to 1.0 when fetching from the half-float formats
instead of leaving it uninitialised. Don't linearize the alpha component
when fetching from sRGB.
