bfae13eaa6 Keep track of pending subscription close. (#478) 
Introduce a pending close map and fire onNoSubscribers only
when there are not subscribed and no pending close.

There are a couple of paths for down track close
- RemoveSubscriber
- RemoveAllSubscriber
We remove the subscriber from `subscribedTracks` in these.
This is because `AddSubscriber` checks for existing subscription.
If there is a remove followed by an add, the add should not think
there is an existing susbcription if there is a delay in down track
close callback.

But, down track close is also called directly from places like
participant close. So, have to clean up both subscribedTrack
and pendingClose when the down track close fires.

Call onNoSubscribers only when both are empty. This will allow
relay up track to stop properly when all susbcribers have left.

* Introducing OpsQueue

Creating a PR to get feedback on standardizing on this concept.

Can be used for callbacks.
Already a couple of places use this construct. Wondering if we
should standardize on this across the board.
Just changing one place to use the new struct. Another place
that I know of which uses this pattern is the telemetry package.

870190624e Fix no-video with adaptive streaming (#456) 
* Fix no-video with adaptive streaming

With a recent change to initialize max quality for subscriber
synchronously, a subsequent update at the same quality was
getting ignored. So, there was no message back to publisher
to start up video layers. Reproducible every time the subscriber
joined after all the layers of publishers was turned off.

While not pretty, for now, disable the check for quality match
on subscriber update. That disabling itself is fine as there is
another check for consolidated quality match before sending
a message to the publisher, but in general this area has shown
some shakiness and needs some work.

* Use notify function to set initial quality also

d69ee14696 Make stream tracker very forgiving for layer 0. (#437) 
With screen sharing in Chrome 97, static content sends one packet
a second. Layer 0 stream tracker was configured to expect 2 per second.
Make it very relaxed so that one packet in two seconds declares layer 0
