mesa: add API dispatch for GL_ARB_get_texture_sub_image

This adds the new glGetTextureSubImage() and
glGetCompressedTextureSubImage() functions.  Also update the
dispatch sanity test program.

v2: remove stray brace, move xi:include line in gl_API.xml, fix extension
number typo, s/program/texture/ in xml file.
