More vblank cleanups.

* Fix crash at context creation in most drivers supporting vblank.
* Don't pass vblank sequence or flags to functions that get passed the drawable
  private already.
* Attempt to initialize vblank related drawable private fields just once
  per drawable. May need more work in some drivers.
