i965/wm: Use resolved miptree consistently in surface setup

Most of the logic refers to the local variable 'mt' directly but
a few cases use 'intelObj->mt' instead. These are the same for
now but will be different once stencil miptree gets used.

v2 (Ian): fixed also indentation in surrounding lines

WIP: freedreno/a3xx: incorrect scissor for binning pass

If scissor optimization is used (to avoid bringing scissored portions of
the render target into GMEM and then back out to system memory) in
combination with hw binning pass, the result would be a scissor mismatch
between binning pass and rendering pass.  This would cause rendering
bugs in some scenarios with (for example) gnome-shell.

I would have expected that simply using the correct screen-scissor
during the binning pass would be enough, but seems like there is
something else missing.  So for now disable binning pass if scissor
optimization is used.
mesa: new init_teximage_fields_ms() function to init MS texture images

Before, it was kind of ugly to set the multisample fields with
assignments after we called _mesa_init_teximage_fields().

mesa: remove remaining uses of _glthread_GetID()

It was really only used in the radeon driver for a debug printf.
And evidently, libGL.so referenced it just to work around some sort
of linker issue.

This patch removes the two calls to the function and the function
itself.

Fixes undefined _glthread_GetID symbol in libGL reported by 'nm'.
Though, the missing symbol doesn't cause any issues on my system but
it does cause glxinfo to fail on one of our test systems.

i965: Fix predicated-send-based discards with MRT.

We need the header setup to not be predicated on which pixels are
undiscarded.  I'm not sure originally if I had thought that the mask
disable implied predicate disable, or if I had just misread the mask
disable as predicate disable.  Either way, I know I had spent more time
thinking about this in the gen8 generator than the gen7 generator.

Plus, it turns out that I had mis-implemented the "the GPU will use the
predicate unless this header is present" comment, by skipping setting up
the pixel mask when the header was present.

Fixes GPU hangs in piglit glsl-fs-discard-mrt, Trine, Trine 2 and
preusmably MLL.

st/mesa: make winsys fbo sRGB-capable when supported

The texture formats of winsys fbo are always linear becase the st manager
(st/dri for example) could not know the colorspace used.  But it does not mean
that we cannot make the fbo sRGB-capable.  By

 - setting rb->Visual.sRGBCapable to GL_TRUE when the pipe driver supports the
   format in sRGB colorspace,
 - giving rb an sRGB internal format, and
 - updating code to check rb->Format instead of strb->texture->format,

we should be good.

Fixed bug 75226 for at least llvmpipe and ilo, with no piglit regression.
