[PULL] glamor cleanups and VBO changes (and glx fix)

[Eric Anholt]

keithp said he was comfortable with the level of review on these, so

get review comments: glViewport() in ephyr, and dropping
glXMakeCurrent(None).

The following changes since commit 7f15e5aed79803fa6057fbfda7dfbacacc2e019d:

  Require video drivers to report that they support server managed fds (2014-03-10 09:08:46 +0100)
