These are temporary, actually, but they'll make follow-on work easier to
implement in a step-by-step manner. Eventually the Map and RowStrideBytes
fields will go into a new swrast_renderbuffer type, but adding that type
now would involve touching a _lot_ of code that'll eventually be removed.
The fields marked as obsolete will go away completely at some point.
That field is only used by swrast code so there's no reason to mess
with it in the gallium state tracker.
This also lets us remove the unused st_format_data() type function and
related code.
mesa: Don't resurrect deleted ARB VAOs in glPopClientAttrib
When ARB VAOs are used, glPopClientAttrib does not resurrect a deleted
VAO or VBO. This difference between the two spec is, unfortunately,
not very well spelled out in the specs.
Fixes oglc vao(advanced.pushPop.deleteVAO) and
vao(advanced.pushPop.deleteVBO) tests.
NOTE: This is a candidate for release branches.

mesa: Rename gl_array_object::VBOonly to ::ARBsemantics
There are more differences between Apple and ARB than just requiring
that all arrays be stored in VBOs. Additional uses will be added in
following commits.
Also, set the flag at Bind time instead of Gen time. The ARB_vao spec
specifies that behavior.
NOTE: This is a candidate for release branches.

swrast: Use fixed-function processing instead _TexEnvProgram for DrawPixels
This is a hack to work around drivers such as i965 that:
- Set _MaintainTexEnvProgram to generate GLSL IR for
fixed-function fragment processing.
- Don't call _mesa_ir_link_shader to generate Mesa IR from the
GLSL IR.
- May use swrast to handle glDrawPixels.
Since _mesa_ir_link_shader is never called, there is no Mesa IR to
execute. Instead do regular fixed-function processing.
Even on platforms that don't need this, the software fixed-function
code is much faster than the software shader code.
NOTE: This is a candidate for the 8.0 branch.

mesa: Make sure _TexEnvProgram points at the current ff fragment program
At least one place, the _mesa_need_secondary_color function in
state.h, uses this to make decisions. The next patch in this series
will add another dependency. Ideally, this field would go away and be
replace by a flag or something.
