Remove querying the indirect rendering context
Review Request #123995 - Created June 3, 2015 and submitted
Mesa fails to make an indirect rendering context current and freezes in the next X11 call. Removing indirect rendering support seems like a workaround for the problem, but realisticly it's no longer interesting what indirect rendering provides if direct rendering is available. If direct rendering is not available, it will pick indirect instead. BUG: 344971
freezes without the patch, no freeze with the patch.
