    mesa: Remove support for GL_MESA_texture_array

    This extension enabled the use of texture array with fixed-function and
    assembly fragment shaders.  No applications are known to use this
    extension.

    NOTE: This patch regresses GL_TEXTURE_1D_ARRAY and GL_TEXTURE_2D_ARRAY
    cases of the copyteximage piglit test.  The test is incorrectly using
    texture arrays with fixed function while only requiring the
    GL_EXT_texture_array extension.  A fix for the test has been posted to
    the piglit mailing list.
