Bug is a sub-task of bug 1118126.
To properly implement the range removal algorithm we need to be able to identify where the random access points in a track buffer are located.
In fragmented mp4, those are:
Stream Access Point of type 1 or 2 as defined in Annex I of ISO/IEC 14496-12.
(ref http://www.w3.org/2013/12/byte-stream-format-registry/isobmff-byte-stream-format.html#iso-random-access-points)
In webm, this is the start of a Cluster (e.g last resync point).
WebM parser provides an API to retrieve those (GetOffsetForTime), mp4 MoofParser doesn't.
API needs to be added to ContainerParser.
