glsl: implement support for GL_EXT_texture_array

GL_EXT_texture_array is different from the existing GL_MESA_texture_array
support in that the former is only supported for GLSL, not fixed-function.

The shadow compare versions of the sampler functions haven't been tested
yet.  The non-shadow versions have been tested with a new piglit test.
