The implementation covers the latest specification, but does not
support mixed-codec simulcast at the moment.
Changing codec for audio and video is supported.

See diff between Patch Set 1 and latest Patch Set.
The original CL broke this WPT[1] because getStats() with the receiver
as the selector stopped working in the event of unsignalled SSRCs due
to the receiver not knowing what the SSRC was.
This fix is to query media_channel_ for the unsignalled SSRC in the
event that the receiver does not know the SSRC.

As the synchronous version only posts a task to recreate the encoder
later, it is not possible to catch errors and state changes that
could appear then.
The asynchronous version of SetParameters() aims to solve this by
providing a callback to wait for the completion of the encoder
reconfiguration, allowing any error to be propagate and subsequent
getParameters() call to have up to date information.

It's normal for a receiver to not be configured to receive, such as when
currentDirection is not (or not yet) "sendrecv" or "recvonly".
getParameters() returning an empty set of encodings is valid and these
logs are not very useful. It's also inconsistent that we only log after
SLD has happened due to different code paths inside getParameters(),
repro: https://jsfiddle.net/henbos/xqksj3wd/.
Most notably we're calling getParameters() internally from inside of
getStats() which can cause excessive log spam. I prefer that we remove
these logs rather than avoid calling getParameters() from inside of
getStats() on non-receiving receivers since it's valid to check how many
encodings exist on a receiver using getParameters(), and whether or not
the SSRC has been signaled could in theory affect the number of
encodings even if we do want to receive. Also an app calling
getParameters() on an inactive receiver is valid and should not cause
logs.
