* WIP commit
* SubscribedQualityUpdate message to send list of currently subscribed
qualities for a simulcast video publisher
* Correct subscriberID
* goimports
* Do quality update on add/remove of subscribed track
* do not update quality when admin mute is active
* update quality on admin unmute
* Update protocol version
* Simplify max subscribed quality loop per David's suggestion
* WIP commit
* deficient handling
* Add missing ProvisionalAllocatePrepare
* adjust state on track removal
* Increase test timeout
* - Add comments about cooperative routines
- Take down transition if available in cooperative scheme
- Use layer comparison when taking down transition. Because of when the
bitrate is measured, it is not always guaranteed bandwidthDelta is -ve
when moving down.
- Do not add track to stream allocator till bind.
* make comment better
* a bit more clear comments
* Use OnBind on subscribed track
* Stream Allocator Try 3
Making an intermediate PR to do
- Special treatment for screen share tracks
- When allocating all tracks,
o try to stream all tracks by starting with the lowest layer
o multi-pass across tracks to get a more even distribution
Not yet done:
-------------
In deficient state,
o Allocate a specific track on a change
o Steal from other tracks
* Correct sense of managed track
* have to range to copy
* generate
* fix VideoLayers compare
* Use t.simulcasted
* Use protocol friendly StreamedTracksUpdate
* WIP commit
* Stream allocator update
* subtract the requested bandwidth as delta from Allocate could be adding to bandwidth
* Calculate delta correctly
* correct comment
* Simplify eventCh per David's suggestion
* Simplifying (hopefully) sfu.DownTrack
* Remove unnecessary check as pdding only packets are dropped before that check
* Temporal filtering max layer
* - Split out forwarder bits into a separate structure
- Address comments from Jie and David
* Remove debug and unneeded stuff
* Fix test
* Remove unneeded default initialization
* WIP branch to hash out down stream allocator.
* Plug more bits of stream allocator
* update protocol
* remove SignalRequest_Simulcast (#154)
* Plug more bits of stream allocator
* Handle simulcast track available layers change
* WIP branch to hash out down stream allocator.
* Plug more bits of stream allocator
* Handle simulcast track available layers change
* Adopt signature of call to AdjustAllocation
* Move StreamAllocator to PCTransport and allocate only for subscriber.
* Move streamallocator to ion-sfu
* Start/Stop of streamallocator
* Use StreamAllocator for subscriber bandwidth management.
* Do not allocate in ADD_TRACK
* Set payload in constructor
* - Add some logging
- Protocol message to notify clients of paused/resumed streams
* named return
* oops correct sense of isPausing
* Update pkg/sfu/streamallocator.go
Committing David's suggestion.

* configurable node track limit
* sample config
* todos
* end of file new line
* default max num tracks
* bandwidth limit
* client message for limit exceeded node
* 10 Gbps default network limit
Small step on the way to making StreamAllocator prioritization of tracks.
With the new callback into StreamAllocator, the idea is to use the
max layer information to do track prioritization.
Testing:
--------
Sanity check that sample app works
* track numParticipants in room
* only track participant if not a hidden participant
* adjust coding style to use ++
* fix typo
* fix missing nil check
* update roomstore with new numParticipants on participantChanged
* only update roomstore if participant is not hidden
* call StoreRoom directly after StoreParticipant when joining/leaving
