[Mesa-dev] Merge of glsl2 branch to master

[Brian Paul]

It looks like function prototypes aren't handled properly.

I've added a new piglit test for this:

$ bin/shader_runner tests/shaders/glsl-function-prototype.shader_test 
-auto

GLSL2 error: 0:3(1): error: empty declaration list

Failed to compile FS: 0:3(1): error: empty declaration list

PIGLIT: {'result': 'fail' }


It's important that this gets fixed before the merge.  Thanks.
