- update lib-jitsi-meet to version with support for replacing participant

Previously gravatars (external resources) were preloaded even if
disableThirdPartyRequests was set to true in the config, as the
config may be empty at the time of preloading.

This basically reverts
a3fb996ff0
while retaining the same properties that prompted it's original intent, namely
avoiding sending the Referrer header.

* Expose raise hand event to external application

* Fix linting issues

* fix the app non existing issue

We were not processing properties which are set (fire properties updated) before the conference joined event is fired.

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 :-)

Also, default to libravatar.

Closes: https://github.com/jitsi/jitsi-meet/issues/4927

Through several avatar work iterations it's no longer used.

Use fetch(), which gives us better control over headers.

Up until now we relied on implicit loading of middlewares and reducers, through
having imports in each feature's index.js.

This leads to many complex import cycles which result in (sometimes) hard to fix
bugs in addition to (often) breaking mobile because a web-only feature gets
imported on mobile too, thanks to the implicit loading.

This PR changes that to make the process explicit. Both middlewares and reducers
are imported in a single place, the app entrypoint. They have been divided into
3 categories: any, web and native, which represent each of the platforms
  respectively.

Ideally no feature should have an index.js exporting actions, action types and
components, but that's a larger ordeal, so this is just the first step in
getting there. In order to both set example and avoid large cycles the app
feature has been refactored to not have an idex.js itself.

getLocalParticipant returns a participant object stored in Redux, not a
JitsiParticipant object.

It's been considered too disruptive and will often misfire especially
if there are issues with the data channels.

It's an evolution of audio-only mode, where we also allow for receiving a remote
screen-share.

Diving deeper: this basically sets last N to 1 or 0 depending on the
availability of a screen-share.

This refactors all handling of audio-only and last N to 2 features in preparation
for "low bandwidth mode".

The main motivation to do this is that lastN is a "global" setting so it helps
to have all processing for it in a single place.
