[Piglit] [RFC] shader_runner branch

I have a branch, called shader_runner, in my local GIT tree that adds a
generic shader test runner.  There is a branch with the same name in the
main piglit GIT tree, but that branch only contains fail.  My lack of
GIT-fu shows.

    git://anongit.freedesktop.org/~idr/piglit shader_runner

It's conceptually similar to vpfp-generic, which is used for assembly
shader tests.  The test files are "ini" style with "[section header]"
section divisions.  The shader code can either be in the test file or
stored in external files.  One of the planned future changes is to
subsume the vpfp-generic functionality so that tests of mixing assembly
and GLSL can be written.

It currently only supports a subset of what we really want (i.e., it
only supports setting vec4 uniforms), but it is very easy to add new
features as needed.

I'd like some review of this branch before I merge it.  In particular,
the code uses some of the portability checks in cmake.  The commits
listed below are the relevant changes.  I'd especially appreciate it if
someone could try building this on OS X and Windows.
