Also implement context member functions to optimize away those
flushes whenever possible.

This fixes a regression in fbotest1 on 915, where a transition from
color+vertex array enabled to texcoord0+vertex array enabled wouldn't trigger
program update on the second _mesa_update_state of DrawArrays, and we'd sample
a constant texcoord of 0,0,0,1 instead of the array.
The double state update in DrawArrays from
1680ef8696 still needs fixing.
There's really no need for two negation fields. This came from the
GL_NV_fragment_program extension. The new, unified Negate bitfield applies
after the absolute value step.
This mostly came down to finding the right MRF incantation in the
brw_dp_READ_4_vs() function.
Note: this feature is still disabled (but getting close to done).
Have to use LINK /LIB instead. The biggest problem is when the command
line is very long and all the options are included in a argument file --
link doesn't like if /LIB is included in the argument file.
It is possible for ctx->DrawBuffer to be NULL, so don't fault when
that happens. This change is not being committed to master because it
doesn't appear to be necessary there.

Cherry picked from mesa_7_4_branch, commit 49e0c74ddd91900fc4effb6d305d56e0563b456d
Hook up a constant buffer, binding table, etc for the VS unit.
This will allow using large constant buffers with vertex shaders.
The new code is disabled at this time (use_const_buffer=FALSE).
We don't update drawables anymore unless they are completely
uninitialized, so we need to swap even if we don't have
cliprects yet, otherwise we never end up calling the driver's
SwapBuffers(). The driver should update the drawable in its
SwapBuffers() anyway.
See 8e753d0404,
"dri glx: Fix dri_util::driBindContext" for the change that
exposed it.
Unfortunately this doesn't catch all the cases, as the mesa state tracker
can still use the framebuffer without giving the wgl state tracker
the chance to lock it.
