I don't see why this is needed and it's not used anywhere.
As long as apps don't call glDeleteTextures, nothing will release them.
And even if they do, we don't use the saved textures anywhere.
Also, BindTexture will fail for deleted textures anyway, so they can't be
popped. The existing code already binds the Name that was saved, not
the texture object that was saved.

Put the fields saved by glPush/PopAttrib into the sub-structure declared
as Attrib. This will make glPush/PopAttrib much faster because it will
only save and restore that structure.

This was inevitable. This gets rid of the malloc/free calls and chaining
each push group in a linked list. Now the whole attribute stack is declared
statically in gl_context.
Yes, this improves performance a lot.

If there are no changes to the matrix, we can move pop the stack but not
update any state constants.

The old path copies state parameters into the parameter list, and then
the driver copies them into a buffer.
The optional new path loads state parameters into a buffer directly.
This increases performance by 5% in one subtest of viewperf.

Drivers should upload only UniformBytes of uniforms and constants,
and then use _mesa_upload_state_parameters to upload state parameters.
This allows removing one copy of state parameters.

Disabled because of CI failures.
Instead of separate state vars for each row and invoking fetch_state 4x:
state.matrix.modelview.row[0]
state.matrix.modelview.row[1]
state.matrix.modelview.row[2]
state.matrix.modelview.row[3]
The rows are now merged and fetch_state is invoked once:
state.matrix.modelview.row[0..3]

This moves state vars to the end of the parameter list, so that state vars
can be loaded directly into a buffer instead of loaded into the parameter list.
Also, state vars don't need to be searched in the parameter list anymore,
because we will know their index range. (this will make gallium faster)
This commit just wraps a for loop around the existing code.

The order of enums is a preparation for a future commit, but if you are
guessing that I just want to copy all light params into a constant buffer
with one memcpy, you are right.

Viewperf does a lot of redundant uniform updates - 60-80% in some tests.
Those are sometimes the only state changes between draw calls.
This improves performance by 33% in one viewperf subtest.
If you are worried about CPU overhead in the non-redundant case,
glthread is the solution.
