avfvideosrc: Get rid of the buffer queue

CHANGES

* Really let AVFoundation do its job

  Instead of dropping frames in the delegate,
  now I simply hog the delegate until the main
  thread finishes its job. AVFoundation is built
  to handle this by queueing and dropping.

* Protect against spurious wakeups

* currentFrame -> delegateFrame

* Consolidate variables into the CaptureFrame
