These will be used by glReadPixels() and glGetTexImage() to fix issues
with reading GL_LUMINANCE and other formats.

GL_RG_INTEGER only has two components, not three. I'll be surprised
if anyone ever tries to glReadPixels(..., GL_SHORT, GL_RG_INTEGER,
...). This was found by inspection.

In the core, we always treat spans of int/uint data as uint, so this
extract function was truncating storage of integer pixel data to a n
int texture to (0, max_int) instead of (min_int, max_int). There is
probably missing code for handling truncation on conversion between
pixel formats, still, but this does improve things.

Mostly fixes piglit EXT_texture_integer/getteximage-clamping. The
remaining failure involves precision loss on storing of int32 texture
data (something I knew was an issue, but wasn't trying to test).
NOTE: This is a candidate for the 8.0 branch.

This aborts and crashes in intel oglconform's int-textures into being
just rendering failures. Clamping isn't handled yet.
v2: Add missing "break".
v3: Drop the int/uint distinction, since they don't need different clamping.
NOTE: This is a candidate for the 8.0 branch.

Adds two missing '|| srcFormat == GL_RG_INTEGER' in assertions and a

This just adds the correct checks and asserts in the right places. This doesn't
fix all the tests that I've sent to piglit, need to add int paths to go alongside the uint paths that don't go via float to fix it up properly.
I'm not sure how much of that could be templated/shared will have a look
once I write it the long way.

We checked if srcType == GL_UNSIGNED_BYTE earlier so there was no
way to reach this code. This was left-over code from the GLchan
removal work.

Rather than redefining the BYTE/SHORT_TO_FLOAT macros, just define new
ones with different names. These macros preserve zero when converting.

This just adds a simple packing for GL_UNSIGNED_INT/GL_INT destination formats.
This is enough for at least the gallium drivers to pack both unsigned and signed types for read pixels.

The EXT_texture_integer issues says:
Should pixel transfer operations be defined for the integer pixel
path?
RESOLVED: No. Fragment shaders can achieve similar results
with more flexibility. There is no need to aggrandize this
legacy mechanism.
v2: fix comments, fix unpack paths, use same comment/code
v3: fix last comment

Also use MAX3 and incorporate Ian's suggestion in texformat.c.
I don't think wrapping u_format_rgb9e5.h in another header and thus making it
more complicated is worth it.

We introduce _NEW_FRAG_CLAMP since fragment clamping has wide-ranging
