In order to optimize DrawPixels, the i915 texenv program isn't
applied to swrast DrawPixels in the i915 driver. This causes this
program isn't applied to any following swrast functions. Resetting
the swrast state fixes this issue. Fix#13614
Two new configure options to add -m32 or -m64 to the CFLAGS and CXXFLAGS
when GCC is in use. By default, the user supplied options are
environment variables are respected, but these options are quick helps
for the common case of x86/x86_64 using GCC.
We probably want to use inline indices in some situations still, but this
commit's primary purpose is to workaround some mis-rendering caused by a
more complicated problem that'll get fixed eventually.
Far more efficient, if not a bit more complicated. Hopefully not too
buggy still.
This commit will potentially expose some unrelated bugs, fixes for them
will follow "real soon now".
Most of the options available from configure are documented on the
autoconf.html. This page is reached as an alternative provided on the
install.html page. An FAQ about why there is no configure script has
been removed.
Try and fit user buffers into a small GART scratch area at validate time,
instead of going to a lot of effort to fit these (mostly) use-once-and-discard
objects into VRAM.

fix missing first/last line segment on gamma, i810, i915, mga, r200, radeon,
s3v, savage, unichrome (r300 already correct). Tested on r200, fixes#13527.
Note that this does not enable GL_EXT_stencil_two_side, because Mesa's computed
_TestTwoSide ends up respecting only STENCIL_TEST_TWO_SIDE_EXT (defaults to
GL_FALSE), even if the application uses only GL 2.0 / ATI entrypoints.
The core problem was that _mesa_generate_mipmap was not respecting RowStride
of the source image. Additionally, the intel private data associated with the
images (level and face) was not being initialized for the
_mesa_generate_mipmap-generated images.
If an app never called glViewport, the viewport size was always 0 by 0 pixels.
Now pass initial size to st_create_framebuffer() and initialize the viewport
and scissor bounds in st_make_current().
This could also be fixed by ensuring the gl_framebuffers passed to
_mesa_make_current() were initialized to the right size. But that involves
allocating the renderbuffers/pipe_surfaces earlier and that runs into some
other issues ATM.
Also remove obsolete createRenderbuffers param to st_create_framebuffer().
