Used to be done in the glVertex/Normal/Color/etc/Pointer() calls but
if the VBO was reallocated the size could change.
New _NEW_BUFFER_OBJECT state flag.
Thanks to branching, the state of c->current_const[i].index at the point
of emitting constant loads for this instruction may not match the actual
constant currently loaded in the reg at runtime. Fixes a regression in my
GLSL program for idr's class since b58b3a786a.
This fixes a crash in glean's pbo test, which tripped over the assert when a
context was destroyed while a buffer was still mapped (Mesa doesn't call
UnmapBuffer in that case). Regression in
c6bde8873f
In radeon_clear_tris(), when clearing the stencil buffer,
pass GL_FRONT_AND_BACK to _mesa_StencilFuncSeparate(), to avoid
triggering a software fallback on r300 and below.

This snuck in with the multi-draw-buffers commit, and is a major penalty
to performance. It doesn't appear to be required, as the only dependency
the surface BO has is on the state key (and if there's some other dependency,
it should just be in the key).
This brings openarena performance up to almost 2% faster than Mesa 7.4.
This can avoid re-uploading constant data when it isn't necessary, and is
a step towards not updating other surfaces just because constants change.
It also brings the upload of the constant buffer next to the creation.
This brings openarena performance up another 4%, to 91% of the Mesa 7.4 branch.
Really, the creation and upload of constants should be in the same place,
since they should only happen together, and a state flag should be
triggered by them so that we don't thrash state around so much for just
updating constants. But this still recovers openarena performance by
another 19%, leaving us 16% behind Mesa 7.4 branch.
The semantics are a little different for shaders vs. fixed-function when
trying to use an incomplete texture. The fallback texture returning
(0,0,0,1) should only be used with shaders. For fixed function, the texture
unit is truly disabled/ignored.
Fixes glean fbo test regression.

remove the r100-ism of swapping cube faces which doesn't apply to r200,
and also use precalculated offsets.
Note that cube textures will still not work on r100 and r200 since mipmap
layout is level-first order (for r300) whereas r100/r200 require
face-first (and possibly also 2k alignment for face at least with tiling).
