OPENGL: Merged from trunk, from rev 52105 to 53396.

This includes an rather hacky attempt to merge all the recent gp2x backend
changes into the branch. I suppose the gp2x backend and probably all new
backends, i.e. gph, dingux etc., might not compile anymore.

Since I have no way of testing those it would be nice if porters could look
into getting those up to speed in this branch.
