With separate stencil GL_DEPTH32F_STENCIL8, the miptree will have a
really different format (MESA_FORMAT_Z32_FLOAT) from the teximage
(MESA_FORMAT_Z32_FLOAT_X24S8).
Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
The format handling here is tricky, because we're not actually
generating a Z32_FLOAT_X24S8 miptree, so we're guessing the format
that GL wants based on seeing Z32_FLOAT with a separate stencil.

gen7 only supports the non-packed formats, even if you associate a
real separate stencil buffer -- otherwise it's as if the depth test
always fails.
This requires a little bit of care in the match_texture_image case,
since the miptree format no longer matches the texture image format.

There were only two places it was really used at this point, which was
in the batchbuffer emit of the separate stencil packets for gen6/7.
Just write in the ->stencil_mt reference in those two places and ditch
all this flailing around with allocation and refcounts.
v2: Fix separate stencil on gen7.

The code didn't handle the case where front wasn't specified in the vertex
shader outputs, but back was.
In that case we were doing a copy from back to non-existant front,
this code checks we have existant front/backs and only does the copy when
they both exist.

It's harmless to add support for attributes we don't support,

Noticed a "warning: array subscript is above array bounds" given at one of
the existing sanity-check asserts. Turns out all the arrays of strings
haven't matched the corresponding enum values in a while, if ever.
I didn't know the proper names for any of these and couldn't find
them in the base specs aside from "result.pointsize" in
ARB_vertex_program, so I just filled in the enum's value
as was done with other slots.
Also add four STATIC_ASSERT()s to be sure and catch future additions
or bumps to MAX_VARYING/etc again, and some more non-static asserts
where there weren't any before.
(Note, the fragment enum that corresponded to result.color(half) was removed in
8d475822e6e19fa79719c856a2db5b6a205db1b9.)

This helper function is used during mipmap generation to prepare space
for the destination mipmap levels.
This improves/fixes two things:
1. If the texture object was created with glTexStorage2D, calling
_mesa_TexImage2D() to allocate the new image would generate
INVALID_OPERATION since the texture is marked as immutable.
2. _mesa_TexImage2D() always frees any existing texture image memory
before allocating new memory. That's inefficient if the existing
image is the right size already.
