Since it is unsafe to hand out a pointer to a packet that might be removed/
overwritten at any time we now return a copy of the header if it exist.

In VP8 the assumption is that a non layer-sync frame depends on all previous
frames on temporal layers less or equal to this frames temporal layer.

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|.

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.
