We need to pass these requests through to the host server in the same
way we do glXMakeCurrent. Generalise the existing MakeCurrent
submission into once that will send MakeCurrent, MakeContextCurrent or
MakeCurrentReadSGI, depending on the request and the host server's
capabilities, and add decoding/hijack support for incoming
MakeContextCurrent and MakeCurrentReadSGI requests.
Fixes Clutter → Xephyr → VirtualBox.
