  Serialize framebuffers + compare contexts for CaptureReplayTests
  
  Adds to frame capture the ability to serialize a frame's pre-swap
  GL state and store it in the binary data file
  Adds to CaptureReplayTests the ability to compare its serialized GL
  state with the serialized state pulled from the binary data file
  Adds a serialization module that serializes framebuffers' GL states
  and the contents of their color attachments
  Adds checks to automation script so that it would skips tests that
  do not produce the expected trace files
  Adds exception handling to automation script so that it will not crash
  when a replay build crashes
