Adds 0-3 textureGather component selection and non-constant offsets
Caveat: 0 and 1 texture swizzles only work if textureGather component
select is 3 or a component that does not exist in the sampler texture
format. This is a hardware limitation, any other value returns
128/255=0.501961 for both 0 and 1.
Passes all textureGather piglit tests on radeon 6670, except for those
using 0/1 texture swizzles due to aforementioned reason.

Map TGSI_SEMANTIC_SAMPLEMASK to register/component.
Enable face register when sample mask is needed by shader.

Add a new winsys and target that can be used with a dri2 state tracker
and loader instead of drisw. This allows to use gbm as a dri2/image
loader and avoid the extra copy from the backbuffer to the shadow
frontbuffer.
The new driver is called "kms_swrast", and is loaded by gbm as a
fallback, because it is only useful with the gbm platform (as no buffer
sharing is possible)
To force select the driver set the environment variable
GBM_ALWAYS_SOFTWARE

- Rebase on top of gallium megadriver.
- s/text/test/ in configure.ac (Spotted by Andreas Pokorny).
- Add scons support for winsys/sw/kms-dri and fix the build.
- Provide separate DriverAPI, due to different InitScreen hook.

Only supported on evergreen and later. Currently limited
to single component textures as the hardware GATHER4
instruction ignores texture swizzles.
Piglit quick run passes on radeon 6670 with all
applicable textureGather tests, no regressions.

The assumption is that any driver capable of emitting layer from the
vertex shader and supporting viewports should be able to also handle
emitting viewport index from the vertex shader.

If multiple viewports are supported, that implies the presence of a GS
and layered rendering, so we can enable ARB_fragment_layer_viewport as
well.

Some of the features are completely implemented by core, while others
have hardware dependencies. Create a list of drivers supporting each
sub-feature that must have hw support.

As far as I can tell, the Intel mesa driver is the only driver in the world
still supporting this legacy extension. If someone wants to do bump
mapping, they can use shaders.

This technique is much neater than trying to override opengl32.dll.

SCons is required for Windows. Add links to flex/bison for Windows.

Both changes landed in 10.2, and for people not following the
development cycle these will come as a surprise. Note that the
pipe_* interface is not stable.
