Update api.md

When a conference is started, the currently used
camera device id is saved. I believe this is happening
because lib-jitsi-meet does not use exact device id
mathcing when calling getUserMedia, so it's possibl
to request camera A but get camera B back because
camera A is not available. When config.startScreenSharing
is true, the syncing occurs and saves the desktop
source id. So when screensharing is stopped, jitsi-meet
requests that desktop source id instead of the preferred
camera.

Adds a new event fired when Jitsi Meet shows the feedback prompt.

The conference disconnection process is asynchronous which means there's
no guarantee that there will be CONFERENCE_LEFT event for the old
conference, before the next conference is joined. Because of that we can
end up with two simultaneous calls on the native side which is not
always supported. End the call on CONFERENCE_WILL_LEAVE to fix this
corner case.

Using an array of styles in Firefox causes an error
that triggers jitsi-meet to redirect to a static page.

They generate a bunch of harmless yet confusing error messages and they are not
really useful.

RTCAudioSession is a thin wrapper around AVAudioSession provided by the WebRTC
framework. It makes some use-cases easier, and leads us closer to manual audio
unit management, which we will likely need in the near future.
