The maxaveragebitrate parameter to be used by Opus can be configured
through the new opusMaxAvgBitrate config option. Values are restricted
by Opus to integers between 6000 to 510000. Works for non-p2p only.

 This is useful for testing insertable streams related issues.

* Move STUN/TURN to IANA-assigned ports - 3478 and 5349 (TLS)

* Change remaining references to TURNS port from 4445 to 5349

* Change back TURNS to 443

- Remove external install dialogs and fix related screensharing error handling.
- Remove obsolete options from config.js and from configWhitelist.js

We are not actively testing it and it currently crashes Chrome 83+ when insertable streams are used.

* ref: disable ICE restart by default

The reason for that it's currently causing issues with signaling when
Octo is enabled. Also when we do an "ICE restart"(which is not a real
ICE restart), the client maintains the TCC sequence number counter, but
the bridge resets it. The bridge sends media packets with TCC sequence
numbers starting from 0.

The 'enableIceRestart' config option can be used to force it, but it's
not recommended.

* debian: Update coturn udp port to non-privileged one.

* debian: Turnserver config requires jitsi-meet-web-config files.

* doc: Updates doc, removing `--no-install-recommends`.

* debian: Moves checks and configs to default to prosody 0.11.

* debian: Disable room locking on internal muc.

* add scripts for deploying coturn with certbot

* turnserver: Removes unused variable showing error.

* debian: updates let's encrypt and coturn scripts.

* debian: Detect failure to retrieve external ip address.

* debian: Always configure turn when the turnserver package is installed.

Some cameras may not be able to satisfy it and gUM will fail.

This reverts commit faf24ca7ec.

This reverts commit 08f55ccb94.

Prevent possible json parse errors when the configuration values are
commented or commented out.

Config.js will allow to specify both BOSH and Websocket URLs. In such
case the web app will prefer Websocket over BOSH. The reason is that it
appears to be more stable and a bit fast on web, while on mobile
websocket is dropped fast(killed by the OS) on network changes.

* feat: display noise detection notification

* address code review p1

* Address code review p2

* bump lib-jitsi-meet version

* Adds package that can configure using turnserver for jitsi-meet.

Activates http2 on the nginx host and uses the alpn send with the web requests to multiplex traffic to be served as web of proxied to the turn server.
It needs nginx at least v1.13.10.
Adds turncredentials module from Philipp Hancke, with small modification (all int values for hosts need to be strings/tostring()) in order to be able to use the module with prosody 0.11.

* Moves loading of stream after loading stream module (50-..).

* Leaves DISABLE_TCP_HARVESTER to be handled by jvb.

* Fixes comments.

* Properly detect first time coturn install and configure it.

* Handles upgrading from jetty serving web.

* Does not create jvb user if already exists.

* Fixes let's encrypt and adds turnserver handling.

* Enables use of turn server in config.js if available.

* Adds a check whether prosody config exists.

There are cases where deployments can still have configured prosody in the main prosody config in /etc/prosody.

* Adds an option to set email through iframe API init and to stats.

* Simplifies configuring email and displayName in stats.

Removes enableStatsID as not needed as when off we are sending as callstats id xmpp resource which is unique per call and id must be something that sticks between calls (callstatsUsername).

* Adds email and displayName in stats config for mobile.

* chore(deps): Updates lib-jitsi-meet to latest dd31f0a.

* Removes enableStatsID from config and whitelist.

They never worked on mobile and pose an impediment for makinf config.js more
future proof. Specially if we want to move to a non-executable form of
configuration.

This adds an option to disable video autoplay that will be used mostly with maleus (our selenium-based load testing tool for testing the new bridge). Disabling video rendering lowers the resource utilisation of the selenium nodes.
