This patch adds the pixel store operations in decompress_texture_image().
decompress_texture_image() is used in glGetTexImage() for compressed
textures with unsigned, normalized values.
It also fixes the failures in intel oglconform pxstore-gettex due to
following sub test cases:
- Test all mipmaps with byte swapping enabled
- Test all small mipmaps with all allowable alignment values
- Test subimage packing for all mipmap levels

This code is unprepared for handling integer (particularly, the
baseFormat of the TexFormat comes out as GL_RGBA, not GL_RGBA_INTEGER,
so the direct call of Driver.ReadPixels crashes due to the int vs
non-int error checking not having happened). I'm frankly tempted to
convert this code to MapRenderbuffer/MapTexImage rather than doing it
as meta ops, now that we have that support.
Improves the remaining crash in Intel oglconform for int-textures to
just a rendering failure.

Replace target, level parameters with gl_texture_image.
Add gl_renderbuffer parameter to indicate source buffer for the copy.
This removes some redundant code in the drivers to find the source
renderbuffer and the destination texture image (which we already had

During meta-operations (such as _mesa_meta_GenerateMipmap()), we need
to be able to draw even if GL_RASTERIZER_DISCARD is enabled. This
patch causes _mesa_meta_begin() to save the state of
GL_RASTERIZER_DISCARD and disable it (so that drawing can be done
during the meta-op), and causes _mesa_meta_end() to restore it.

If they were disabled on entry, and we enabled one (like for
BlitFramebuffer), we wouldn't disable it on the way out. Retain the
attempted optimization here (don't keep calling to set each bit for
changes that won't matter) by just setting the bits directly with
appropriate flushing.

This hook allows the driver to prepare for a glBegin/glEnd.
i965 will use the hook to avoid avoid recursive calls to FLUSH_VERTICES
during a buffer resolve meta-op.
Detailed Justification
----------------------
When vertices are queued during a glBegin/glEnd block, those vertices must
of course be drawn before any rendering state changes. To enusure this,
Mesa calls FLUSH_VERTICES as a prehook to such state changes. Therefore,
FLUSH_VERTICES itself cannot change rendering state without falling into
a recursive trap.
This precludes meta-ops, namely i965 buffer resolves, from occuring while
any vertices are queued. To avoid that situation, i965 must satisfy the
following condition: that it queues no vertex if a buffer needs resolving.
To satisfy this, i965 will use the PrepareExecBegin hook to resolve all
buffers on entering a glBegin/glEnd block.
--------
v2: Don't add dd_function_table::CleanupExecEnd. Anholt and I discovered
that hook to be unnecessary.

If this flag is set, then _mesa_meta_begin/end will save/restore the state of
GL_SELECT and GL_FEEDBACK render modes.
Intel's future buffer resolve meta-ops will require this, since buffer resolves
may occur when the GL_RENDER_MODE is GL_SELECT.

When saving the active program in _mesa_meta_begin, it was actually
saving the fragment program instead. This means that if the
application binds a program that only has a vertex shader then when
the meta saved state is restored it will forget the bound program.

The GL spec says that luminance values are returned as (l, 0, 0, 1),
L/A values as (l, 0, 0, a) and intensity values as (i, 0, 0, 1).

If we're generating a mipmap for an sRGB texture we need to bypass
sRGB->linear conversion. Otherwise the destination mipmap level
(drawn with a textured quad) will have the wrong colors.
If we can't turn of sRGB->linear conversion (GL_EXT_texture_sRGB_decode)
we need to use the software fallback for mipmap generation.
