OSMF SVN

Fix bug FM-957

Submit new classes added

Add multicast net loader to the media factory

First code submission of multicast implementation

Code change to the fix for FM-934

Fix bug FM-934 and add a corresponding unit test. DVRCastNetLoader does not only checks streamType but also checks corresponding metadata under keys of DVRCastConstants.RECORDING_INFO_KEY and DVRCastConstants.STREAM_INFO_KEY

Adding additional fix to bug FM-925. We need to rip off the parameters from oldStreamName. Otherwise play2 will not work correctly.

Zeri Certification Program related code submission, adding more logging messages to OSMF framework

Initial code check-in for the Zeri Certification program

This code change is a result of solving a customer issue, which is OSMF player stutters initially when playing live contents. The solution is to increase the bufferTime to 4 seconds for http streaming live contents.
