mesa: minor reformatting, new comments

progs/xdemos: fix up GLX extension checking

A few of my programs were using the client string in addition to the
main extensions string to see if a feature was present.  Correct this to
only check for the currently available and working extensions.

DRI2: expose OML_sync_control if possible

If the server supports the OML related protocol, enable support for the
extension.

GLX: remove debug prints from glXWaitForMscOML dispatch

Leftover from earlier commit.

xdemos/omlsync: add waitformsc and swap interval code

progs: Add arbocclude2 demo.

gallium/docs: updated/improve sampler state documentation

docs: document GL_APPLE_object_purgeable

mesa: whitespace fixes, 80-column wrapping, etc.

Merge branch 'object-purgeable'

mesa/es: Update GLAPI and APISpec for GL_OES_EGL_image.

This generates the entrypoints and dispatches for GL_OES_EGL_image.
There is no real support yet.

st/egl: Add support for EGL_KHR_image_base and EGL_KHR_image_pixmap.

These extensions are not quite useful until the client APIs gain support
for the respective EGLImage extensions.

st/egl: Add get_param to native display interface.

get_param can be used to query the parameters of a native display.
There is only NATIVE_PARAM_USE_NATIVE_BUFFER right now.  It queries
whether the window/pixmap surfaces use the native buffers instead of
private buffers.

st/egl: Move modeset interface to native_modeset.h.

native.h is getting more and more complex.  Move the independent modeset
interface to native_modeset.h to simplify native.h a little.

st/egl: Add event support to the native display interface.

There is only invalid_surface event right now.  When EGL receives the
event, it sets the force_validate flag of the context binding to the
surface.  This helps skip an unnecessary check.

Revert "mesa: Remove pointless comparison of unsigned integer with a negative constant."

This reverts commit a05fdbcb719ac64e6be842372813f0f4ca2f4f93.

Removing the comparison is wrong. The comparison with -1 should be changed
to another value (probably PROGRAM_UNDEFINED) along with another
change in the shader assembler.

Conflicts:

src/mesa/shader/prog_execute.c

intel: Remove non-kernel-exec-fencing support.

Shaves 60k off the driver from removing the broken spans code.  This
means we now require 2.6.29, which seems fair given that it's a year
old and we've removed support for non-KMS already in the last release
of 2D.

intel: Remove the unused s8 spans code.  Not hit during no_rast piglit.

Shaves 5.5k off of the driver.

Fix comparison of unsigned value against < 0.

softpipe: minor tweaks to texture filtering code

gallivm: implement texture border color, plus tweaks to some wrap modes

The progs/test/texwrap demo looks pretty good, but there are still some
tiny differences from softpipe.  There may be a sub-pixel texcoord
interpolation error somewhere.

There's some room for optimization.  Many of the wrap modes compute
intermediate values that are constant for the texture size (see the
min/max values).  These could be computed earlier and stored somewhere
for later use.

r300g: Fix indexbuf upper limits.

Wine tends to pessimistically use ~0 for its max index, but r300s
only can go up to 2^24-1, causing the kernel checker to freak out.

gallivm: rework and implement more texture wrap modes

All the texture wrap modes are now implemented for linear and nearest
sampling.

However, texture border color is not yet supported so some wrap modes
will produce int coords outside the texture bounds.  We'll get garbage
values insted of the texture border color for now.

gallivm: added lp_build_fract()

gallivm: added lp_build_set_sign()

gallivm: added lp_build_negate()

gallivm: clarify unsigned vs. signed integer type construction

The lp_int_type() function was creating an unsigned type.  So rename
that function to lp_uint_type() and create new lp_int_type() that
creates a signed type.

i915: Enable texture tiling by default.

This now passes piglit testcases, and shows performance improvements
on openarena.  Blit-heavy apps may see degradation, but the
expectation is that the common case of 3D rendering will see
significant wins.

This regresses gen-teximage on my 855, and no piglit tests on my 945.

i915: Fix up i830 for tiled drawing offsets.

Corresponds to b87406e55f029d29594ae76a4b39a4fe1007fe4f.

DRI: Put back missing break-statement

Only tested this on my rv530 with R300_NO_TCL=1, but it works there
at least. It would be nice to fix the tex_offset by chaning the vertex
program on tcl to read from offset 6 but this isn't really necessary.
