OSMF SVN

Fixed "comparing apples with melons" bug (httpstreaming/f4f/HTTPStreamingF4FIndexHandler.as).
Prototype show-casing how the client responds to the windowDuration parameter (hard-coded for the moment).

The other two rolling window branches should be deleted.

Update for LBA
- fix seeking
- use the download information for main stream to calculate download ratio

Update for LBA
- after an index ready update, the HTTPNetStream will enter LOAD_SEEK state and not SEEK
- revert some changes in HttpStreamingF4FIndexHandler which affect the LBA mixing

Third phase HDS refactoring
- LBA reactivated (VOD and LIVE)
- HTTPStreamingF4FMixer updated to use FLV classes inside org.osmf.net.httpstreaming.flv packages
- minor modifications in order to minimize the updates of mixer internal buffers ( the internal buffers are reallocated only after we use at least half of their content)
- updated the mixing algorithm inside onMainTimer in HTTPNetStream
- mixer class is responsible to signal that is missing audio or video data
- update HTTPNetStream to wait for alternative audio initialization before it actually start playing data

IMPACT:
- no public API was affected

*NOTES*
- we still have unit tests and integration tests which fail
