Looks like audio devices must be re-set after focus was lost and regained.
Otherwise some devices (tested on a Samsung Galaxy S9) are in a weird state
where the second microphone is not used when speakerphone is on.

While the base URL remains configurable, this patch reverts back to using
Gravatar.

We noticed high latency with libravatar and contacted them. They are in the
process of migrarting to a better infrastructure (it's a single personal server
at the moment) so we'll re-evaluate once that has happened.

As for why not leave the default and change it on the meet.jit.si installation,
we don't want to kill their server :-)

As per @fremzy, the "Save Logs" feature generates a json
file with a bevy of technical information about the
meeting. This log contains the server name, server IP
address, participant's IP addresses (only in p2p sessions)
e.t.c. While this may be a useful feature for the
admin-like 'moderator', it creates unnecessary exposure
when made readily available to all users in the meeting.

This commit fixes #8036 by a config.js option to enable
the link (disabled by default), thus giving the owner of
the deployment the choice of enabling it or not.

When trying to auto pin screenshare, always select the endpoint even though it happens to be the large video participant in redux. The auto pin screenshare logic kicks in after the track is added.  If the screenshare endpoint is not among the forwarded endpoints from the bridge, it needs to be selected again.

If limitLastN values are specified and channelLastN < limitLastN, configure channelLastN on the conference.

Also, default to libravatar.

This is needed for the torture clients to determine the video type for the remote participants when testing desktop share.

We stopped providing a way to set them, so don't render them either.

Also cleanup some leftover config options.

* fix(Toolbox) Maintain overflow button visible at all times

* Make changes only on desktop browser

Safari 14.1 has a bug where it returns 720p for every simulcast stream when RTCRtpSender.getParameters is called even though the stream resolutions are different.
By using the encodings config used when source was added, on every RTCRtpSender.setParameters call, we ensure that simulcast stream resolutions don't change.

* feat: Drops filmStripOnly mode.

* squash: Let's make lint happy again.

* squash: Drop some css.

This will make browsers not cache results in cleartext.
