mesa: replace GLenum with GLenum16 in common structures (v4)

v2: - fix glGet*
    - also use GLenum16 for DrawBuffers
v3: - rebase to top of tree (BrianP) and incorporate Ian's suggestions
v4: - fix a GLenum16 bug in VBO/save code, add some STATIC_ASSERT()s

gl_context = 152432 -> 136840 bytes
vbo_context = 22096 -> 20608 bytes
