OSMF SVN

First check in to support stream metadata in http streaming.

PARB changes: Refactor NetLoader/NetConnectionFactory relationship. Lots of minor changes, but the major one is to introduce NetConnectionFactoryBase as a subclass of NetConnectionFactory. This simplifies the work needed to inject a live NetConnection into a NetLoader.

Updated Akamai plugin, unit tests, and sample apps accordingly.
