* Send stream state paused only when it is paused due to bandwidth limitation.
When stream is resumed after a stream is paused, an active update is
sent. Note that this means if there are intervening events like
mute/unmute between pause and resume, resume will be sent.

- Cleaning up code
- Two tweaks
o A layer is declared active on receiving first packet (when starting fresh).
But, if there are no frames after that (no packets after girst packet or
there is only one frame), layer would not have been declared stopped as
the previous version waited for second frame. Now, if there are no more
frames in eval interval, declare the layer stopped.
o When frame rate goes to 0, reset FPS calculator. Otherwise, layer starting
after a long time will have frames spaced apart too far which would result
in very low frame rate. Reset the calculator and let it pick up after the
the layer restarts
- Also changing from lowest FPS -> estimated FPS and update up slowly and down fast.
There are cases where frames are to far apart result in really low FPS. Seems to
happen with NLC kind of cases where bandwidth is changed rapidly and the estimator
on browser probably gets a bit confused and starts/stops layers a bit erratically.
So, update estimate periodically to ensure eval interval is tracking current rate.
* fix factor
* spelling fix
* Split stream tracker impl from base
* slight re-arrangement of code
* fps based stream tracker
* MinFPS config
* switch back to packet based tracker
* use video config by default to handle sources without type
