* `hls-608` usage event triggered on `tech`
* Only flush PES packets from TS parsing front end when they are complete
* Complete is defined as any time PES_packet_length matches the data’s length OR is a video packets
* Works around an issue with incomplete packets getting sent down the pipeline when the source has audio PES packets split between segments
* Break out playlist selector logic
Pull the basic playlist selector into a separate file so there's a shared place to build alternates.
* Create a moving-average playlist selector
Define a variant of the standard playlist selector that calculates a moving average of bandwidth and uses that to select a playlist.
* ts probe searches packets for first it can successfully parse
* Fixed an issue that could cause updateend events to fire more than once per append or remove under very specific conditions on firefox
* add playback watcher check for unknown player waiting
* do not do unknownwaiting check when the tech fires a native waiting event
* dont track current time waiting when at the end of the buffer
* call techWaiting_ when we detect a stall at the end of buffer
* first draft at fixing bandwidth tester and playing around with abr/bandwidth calculations
* More fixes and better per-millisecond resolution for simulation
* More fixes to allow reverting of non-network-simulation files back to their original content
* Added the ability to change bitrates and minor ABR settings
* Added a server that can simulate network conditions based on a network trace file
Added the ability to specify segment sizes for the simulator to simulate a specific video
Changed the simulator to use average bitrates for segment sizes if they are provided
* use specified mediasequence for VOD expired sync instead of assuming 0
* use synccontroller for expired
* target sync-point by index for expired instead of time 0
* minor fixes
* add vod test for expired
* If beforeRequest is set, reuse it on source changes
* Allow changing global xhr beforeRequest at runtime
* Always use latest beforeRequest instead of setting it when creating hls object
