no context type flags are set and the context remains at NONE.
Assume in this case that gl_colorspace is true, otherwise the
feat_srgb_write_control flag will be cleared and the guest only
gets OpenGL 2.1 compatibility.

v2: Instead of releasing the UBO's at the end don't reference count them.
The guest keeps track of these resources and their reference counts,
so it will not release the UBO's without re-setting the binding during
the live time of a client progra, However, at final clean up the UBO's
are not rebound before the resourse is released in the guest side resulting
in the memory leak. When we skip the ref-counting on the host side the
resourses are cleaned up correctly without breaking the program otherwise.
Fixes resource leaks:
Direct leak of 2448 byte(s) in 9 object(s) allocated from:
