A couple of fixes from the previous pull request as well as gl3 support.
There is one drm core change, an export of a previously private function.
Take 2 implementing screen targets, this time with the fbdev code adjusted
accordingly.
Also there is an implementation of register-driven command buffers, that
overrides the FIFO ring for command processing. It's needed for our upcoming
hardware revision.
