glsl: Remove shader stage checking for extension handling.

Certain extensions only add functionality to particular shader stages.
(For example, ARB_draw_instanced only adds variables to the vertex
shader stage.)

Previously, we only allowed such extensions to be enabled in the shader
stages where they're useful.  However, I've never found any text which
mandates that behavior; in my opinion, you should be able to turn on
extensions in any shader stage, even if they have no effect.

Fixes Piglit tests glslparsertest/glsl2/draw_buffers-05.vert and
ARB_draw_instanced/preprocessor/feature-macro-enabled.frag.

i965: Don't create a swrast context on ES2+.

We already skip this for API_OPENGL_CORE; ES2+ is very similar.
The primary user of the swrast context is GL_SELECT and GL_FEEDBACK,
which have never existed in ES.

This saves approximately 18MB of memory in GLBenchmark 2.7 Egypt (ES2).
No regressions in es3conform on Ivybridge.

build: unify mesa version by using a VERSION file

Rather than having to keep track of all the build systems and their respecitve
definition of the mesa version, use a single top file VERSION. Every build
system is responsible for reading/parsing the file and using it

v2:
* remove useless bulletpoint from the documentation, suggested by Matt
* "Androing is Linux. Use '/' in stead of '\'", spotted by Chad V
* use cleaner code to get the version in scons, suggested by Chad V

v3:
* ensure leading and trailing whitespace characters are stripped while parsing
* android: handle GNU shell commands approapriately

mesa: Remove broken assertion about enabled texture targets.

For GLSL programs, enabledTargets can have more than one bit set.  For
example, a shader that uses sampler2D and samplerCube uniforms will have
both TEXTURE_2D_BIT and TEXTURE_CUBE_BIT set.

The code that sets _ReallyEnabled already handles this, selecting the
"highest priority" texture target.  We should simply use that.

r600g/compute: Added missing address space checking of kernel parameters

To have non-static buffers in local memory, it is necessary to pass them
as arguments to the kernel.

For r600, the correct lds size must be set to the SQ_LDS_ALLOC register.
The correct size is the clover size plus the size reported by the
compiler.

glsl: Remove bogus check on return value of link_uniform_blocks().

A comment in link_intrastage_shaders(), and an if-test that followed
it, seemed to indicate that link_uniform_blocks() would return a
negative value in the event of an error.  But this is not the
case--all error checking has already been performed by
validate_intrastage_interface_blocks(), and link_uniform_blocks() can
only return unsigned values.

So get rid of the if-test and change the return type of
link_intrastage_shaders() to clarify that it can only return unsigned
values.

glsl: Use a consistent technique for tracking link success/failure.

This patch changes link_shaders() so that it sets prog->LinkStatus to
true when it starts, and then relies on linker_error() to set it to
false if a link failure occurs.

Previously, link_shaders() would set prog->LinkStatus to true halfway
through its execution; as a result, linker functions that executed
during the first half of link_shaders() would have to do their own
success/failure tracking; if they didn't, then calling linker_error()
would add an error message to the log, but not cause the link to fail.
Since it wasn't always obvious from looking at a linker function
whether it was called before or after link_shaders() set
prog->LinkStatus to true, this carried a high risk of bugs.

get-pick-list.sh: Include commits mentionining "CC: mesa-stable..." in pick list

We recently adopted a new convention that patches can be nominated for the
stable branch by including a line in the commit message as follows:

	CC: mesa-stable@lists.freedesktop.org

This is a convenient syntax as "git send-email" will notice this line and
automatically copy the resulting patch email to the mesa-stable mailing list.

Here we extend the regular expression in the get-pick-list.sh script to also
notice this pattern, (as well as the traditional "NOTE: This patch is a
candidate..." form.
