Make poster frame example unloadable.

Fix FM-556: When MediaPlayer enters error state, capabilities should be set to false, and capability change events should be dispatched. Also fixed typo in one of the capability change event names.

Refixing preloader example after the false and true were swapped in a refactoring. FM-518.

Fix bug FM-555: RTE when SerialElement child has a load error.

Fix bug FM-331: Unable to seek within a temporal element. The bug is due to the composite SeekTrait being initialized prior to the composite TimeTrait, which it depends on. The fix is for the composite SeekTrait to listen for the composite TimeTrait being added or removed. Note that this required an API addition on the base SeekTrait, exposing a protected setter for the TimeTrait (a protected getter already existed).

Fix bug FM-373: SerialElements can't seek if certain children are unseekable. Updated RTMPPosterFrameElement to use a ProxyElement-based approach with blocked traits (much simpler and more robust).

Make this class private such that it does not show up in the ASDcos.

First check in of DVR support.

Better fix for FM-530. Instead of relying on the Play.PublishNotify event (which won't get dispatched for streams that are already published) to enter the playing state, check the bufferTime value and immediately exit buffering mode if it's zero. In that case (which seems to only happen with live), the Play.Start event is the last one we'll get, so we can't rely on a Buffer.Full event (which makes sense if bufferTime is zero).

Modify LoadFromDocumentElement so that it doesn't use a custom event to signal loaded.
