The point size min/max registers (unused by mesa state tracker) were removed
since most hardware couldn't do much with them. However, we don't want to have
to rely on hw to do point size clamping correctly to implementation
dependent limits, hence have to do that in the vertex shader. This should also
solve a potential problem with (non-AA) points smaller than 1.0 which according
to OGL still have size 1.0.
Note that OGL point rendering is odd, in particular point sprites are rasterized
differently to points. Some hardware might support those different modes, but in
any case the different clamping values used for smooth/multisampled/sprite
enabled points might help a bit for hw which rasterizes points the same as point
sprites.
Also tweak mesa's ff to vertex shader translation so don't have to clamp twice in
case of point attenuation.

We were misinterpretting GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS previously.
It's the number of texture units for which we need to keep state; not
just the total number of texture units addressable by the vertex shader
plus fragment shader.
Since sw Mesa independently supports 16 texture units in vertex shaders
and 16 texture units in fragment shaders, the max combined units is 32.
Note that the docs for glActiveTexture() indicate the max legal unit is
MAX(GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS, MAX_TEXTURE_COORDS) - 1.
A new piglit test (texunits.c) tests the various texture unit limits.
I'm pretty sure I've got this all right now, but additional reviews
are welcome...

These are limited to the number of texture coordinate units.

This should make things easier for drivers wanting to work with a
"subclass" of gl_framebuffer.
The complementary "_mesa_initialize_framebuffer" function is now
called "_mesa_initialize_window_framebuffer" for the sake of
symmetry.

It will be useful for the nouveau DRI driver and IMHO there's no
reason to keep it private.

...rather than checking/validating before all the calls to
_mesa_valid_to_render() and valid_to_render().
The next patch will actually fix some bugs...

Exposing it was incorrect, as the GLSL part of the extension is
missing.
We still keep the ARB_fragment_coord_conventions field, so that the
ARBfp parser can know whether to accept or reject the keywords.

Merging was easier than cherry picking in this instance.

If GL_EXT_framebuffer_blit was not supported _mesa_DeleteFramebuffersEXT
would raise an error when deleting the currently bound framebuffer. This
because it tried to bind the default DRAW- and READ_FRAMEBUFFER separately.
This patch binds the default FRAMEBUFFER instead in that case.
Encountered in the fbo/fbo-copyteximage piglit test on R600.
Patch cleaned up a bit by Brian Paul.

Eric added some new code to check if offset < obj_size before computing
_MaxElement but my original code was still present afterward and it
clobbered the _MaxElement value.
Not sure if this came from a bad merge or what.

Removed _glapi_noop_enable_warnings() and _glapi_set_warning_func().
Just check the DEBUG env vars and call fprintf(stderr) with a warning
message instead.

Sun cc 5.9 and later (__SUNPRO_C >= 0x590) support __attribute__ calls
for aligned, always_inline, noinline, pure, const, and malloc.
This commit includes updates to files that were regenerated by gl_XML.py
after adding the __SUNPRO_C checks to it
