When we concatenate shaders to do our form of poor-man linking, if there's
multiple #version directives, preprocessing fails. This change disables
the extra #version directives by changing the first two chars to //.
This should help with some Wine issues such as bug 23946.
Unless we're cross compiling, the HOST_CFLAGS should be the same as the
normal CFLAGS. This allows the x86 and x86_64 asm to be built correctly
with a native compiler using -m32/-m64.

This fixes a bug seen when doing a glDrawPixels(GL_STENCIL_INDEX) right
after a glClear(). The check-for-flush test was failing because we
didn't set the dirty_render_cache flag in softpipe_clear(). So we saw
stale data when we mapped the stencil buffer.

Hopefully this will be one of the last cherry-picks.

The rule added in 488b3c4d1b does not use the
right INCDIR, breaking the build when GL isn't installed in the default include
paths.
7.5 branch only fix, already fixed in master by rewriting the Makefile

For some IZ setups, we'd forget to account for the source depth register
being present, so we'd both read the wrong reg, and write output depth to
the wrong reg.
Bug #22603.
(cherry picked from commit f44916414e)
Fixes piglit glsl-vs-if-bool and progs/glsl/twoside, and will likely be
useful for the looping code.

This avoids sending a bad buffer address to the GPU due to programmer error,
and is permitted by the ARB_vbo spec. Note that we still have the opportunity
to dereference past the end of the GPU, because we aren't clipping to a
correct _MaxElement, but that appears to be harder than it should be. This
gets us the 90% solution.

See comment on Vertex URB Entry Read Length for VS_STATE.
This, combined with the previous three commits, fixes#22945.
(cherry picked from commit e340d4f986)
It appears that sometimes Mesa (and I suppose a VS could as well) emits
a program which references no vertex data, and thus we end up with
nr_enabled == 0 even though some VBs are enabled. We'd end up emitting
VB/VE packet headers of 0xffffffff in that case, leading to GPU hangs.
