In the future we would like to have a format conversion library that is
independent of GL so we can share it with Gallium. This is a step in that
direction.

Notice that _mesa_format_convert does not handle byte-swapping scenarios,
GL_COLOR_INDEX or MESA_FORMAT_YCBCR(_REV), so these must be handled
separately.
Also, remove all the code that goes unused after using _mesa_format_convert.

We only use _mesa_make_temp_ubyte_image in texstore.c to convert
GL_COLOR_INDEX to RGBA, but this helper does more stuff than this.
All uses of this helper can be replaced with calls to
_mesa_format_convert except for this GL_COLOR_INDEX conversion.
This patch extracts the GL_COLOR_INDEX to RGBA logic to a separate
helper so we can use that instead from texstore.c.
In future patches we will replace all remaining calls to
_mesa_make_temp_ubyte_image in the repository (related to compressed
formats) with calls to _mesa_format_convert so we can remove
_mesa_make_temp_ubyte_image and related functions.

For glReadPixels with a Luminance destination format we compute luminance
values from RGBA as L=R+G+B. This, however, requires ad-hoc implementation,
since pack/unpack functions or _mesa_swizzle_and_convert won't do this
(and thus, neither will _mesa_format_convert). This patch adds helpers
to do this computation so they can be used to support conversion to luminance
formats.
The current implementation of glReadPixels does this computation as part
of the span functions in pack.c (see _mesa_pack_rgba_span_float), that do
this together with other things like type conversion, etc. We do not want
to use these functions but use _mesa_format_convert instead (later patches
will remove the color span functions), so we need to extract this functionality
as helpers.

We have _mesa_swap{2,4} but these do in-place byte-swapping only. The new
functions receive an extra parameter so we can swap bytes on a source
input array and store the results in a (possibly different) destination
array.
This is useful to implement byte-swapping in pixel uploads, since in this
case we need to swap bytes on the src data which is owned by the
application so we can't do an in-place byte swap.

The new parameter allows callers to provide a rebase swizzle that
the function needs to use to match the requirements of the base
internal format involved. This is necessary when the source or
destination internal formats (depending on whether we are doing
the conversion for a pixel download or a pixel upload respectively)
do not match the base formats of the source or destination
formats of the conversion. This can happen when the driver does not
support the internal formats and uses a different format to store
pixel data internally.
For example, a texture upload from RGB to Luminance in a driver
that does not support textures with a Luminance format may decide
to store the Luminance data as RGBA. In this case we want to store
the RGBA values as (R,R,R,1). Following the same example, when we
download from that texture to RGBA we want to read (R,0,0,1). The
rebase_swizzle parameter allows these transforms to happen.

v2 by Iago Toral <[email protected]>:
- When testing if we can directly pack we should use the src format to check
if we are packing from an RGBA format. The original code used the dst format
for the ubyte case by mistake.
- Fixed incorrect number of bits for dst, it was computed using the src format
instead of the dst format.
- If the dst format is an array format, check if it is signed. We were only
checking this for the case where it was not an array format, but we need
to know this in both scenarios.
- Fixed incorrect swizzle transform for the cases where we convert between
array formats.
- Compute is_signed and bits only once and for the dst format. We were
computing these for the src format too but they were overwritten by the
dst values immediately after.
- Be more careful when selecting the integer path. Specifically, check that
both src and dst are integer types. Checking only one of them should suffice
since OpenGL does not allow conversions between normalized and integer types,
but putting extra care here makes sense and also makes the actual requirements
for this path more clear.
- The format argument for pack functions is the destination format we are
packing to, not the source format (which has to be RGBA).
- Expose RGBA8888_* to other files. These will come in handy when in need to
test if a given array format is RGBA or in need to pass RGBA formats to
mesa_format_convert.

If we need the base format for a mesa_array_format we have to find the
matching mesa_format first. This is expensive because it requires
to loop through all existing mesa formats until we find the right match.
We can resolve the base format of an array format directly by looking
at its swizzle information. Also, we can have _mesa_get_format_base_format
accept an uint32_t which can pack either a mesa_format or a mesa_array_format
and resolve the base format for either type. This way clients do not need to
check if they have a mesa_format or a mesa_array_format and call different
functions depending on the case.
Another reason to resolve the base format for array formats directly is that
we don't have matching mesa_format enums for every possible array format, so
for some GL format/type combinations we can produce array formats that don't
have a corresponding mesa format, in which case we would not be able to
find the base format. Example format=GL_RGB, type=GL_UNSIGNED_SHORT. This type
would map to something like MESA_FORMAT_RGB_UNORM16, but we don't have that.

_BaseFormat is a GLenum (unsigned int) so testing if its value is
greater than 0 to detect the cases where _mesa_base_tex_format
returns -1 doesn't work.
Fixing the assertion breaks the arb_texture_view-lifetime-format
piglit test on nouveau, since that test calls
_mesa_base_tex_format with GL_R16F with a context that does not
have ARB_texture_float, so it returns -1 for the BaseFormat, which
was not being caught properly by the ASSERT in init_teximage_fields_ms

If you had a conditional assignment of an array or struct (say, from the

type, and it would assertion fail due to vector_elements==0. Instead,
extend emit_block_mov() to handle emitting the conditional operations,
which also means we'll have appropriate writemasks/swizzles on the CMPs
within a struct containing various-sized members.
