Um. So, yeah. Two massive WTF moments here. The first one is that, somehow,
I never actually hooked up vertex shader emission, so the only time that the
VAP gets set up is during surface_copy/surface_fill. That's why acidgears
was happening.
The second one is that, somehow, once I actually hooked it up, glxgears just
magically worked. Without any actual, real testing, I somehow accidentally
made the shader compiler work. Go figure.

Can be used to enable/disable extensions as reported by
glGetString(GL_EXTENSIONS).
If a name is preceeded by '-' it's disabled. Otherwise, the named
extension is enabled.
Intended for debug/test purposes.
It's legal for ARB_vertex_program programs to not write to result.position.
The results are undefined in that case. This assertion was causing us to
abort/exit though.
The recent increase ST_MAX_SHADER_TOKENS to 8K causes stack overflows on
windows.
Failure to allocate is not being propagated to the caller. This is not
a regression since the previous _mesa_malloc result wasn't being
checked as well. Unfortunately it is not easy to fix, as the callers of
these functions do not have failure propagation mechanism either, and
so on. So leaving a just fixme note for now.
We were adding references to the input arrays, but failing to drop
them on destruction. This could lead to a 64kb buffer being leaked
each context destruction.
1) Pass the correct format when calling update_array in
_mesa_VertexAttribPointerARB.
2) glVertexAttribPointerNV accepts GL_BGRA format too.
3) raise INVALID_VALUE error when format is BGRA and normalized is
false in glVertexAttribPointerARB
