In order to be able to clear out any potentially stashed old frames from
the RtpFrameReferenceFinder we can now clear frames that contain packets
older than |seq_num|.

Since all FrameObjects have a reference to its PacketBuffer and since
the PacketBuffer can be thrown away at any moment the PacketBuffer
has to be ref counted in order to avoid FrameObjects dereferencing a potentially
destroyed object.

In order to correctly determine the references of a frame when using Vp9
with GOF one has to wait for all frames on the lower temporal layers
to make sure no up-switch point is missed.
This patch fix a bug where upon receiving a frame the RtpFrameReferenceFinder
would try to add missing frame for a group with a not yet knows scalability
structure.
