Added Adobe Pass Plugin to samples

Created branch for Rolling Window

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

Modified the HSF4FIndexHandler - it now updates the bootstrap regularly (approx. each fragment) in both Play and Paused states.
