This is just the stepping stone towards the goal of eventually having
lib-jitsi-meet fully written in JS.

- introduce ts-loader for webpack
- webpack will continue generating the UMD bundle
- tsc will generate an ES6 module
- output all bundles to dist/

* ref(JingleSession) Recycle m-lines by rejecting them on source removal.
By rejecting the m-lines on source removal (setting the port to 0 on the associated m-line), m-lines can be recycled for new sources instead of appending new ones.

* chore(deps) update sdp-interop@latest.

Improve compatibility with Webpack 5.

We are not actually using it here.

The direction was marked as 'inactive' only on Firefox as Safari had audio issues when an inactive mid is re-used. Chrome (in unified-plan) needs the direction of the mid in remote desc to be set to 'inactive' for a 'removetrack' to be fired on the associated media stream whenever a remote source is removed.

It dropped Edge support so we get 30K back!

Older chrome versions like M72 do not support Promise.allSettled.

Fix Safari RTCSessionDescription.sdp readonly
Based on https://bugs.chromium.org/p/chromium/issues/detail?id=1186456&

Adds a JitsiConference.getSsrcByTrack() method that finds the SSRC of a JitsiTrack by its SSRC. This method is currently used to get (and display) the first audio/video SSRC in the GSM popover in Jitsi Meet.

This the second stage in our E2EE journey.

Instead of using a single pre-shared passphrase for deriving the key used for
E2EE, we now establish a secure E2EE communication channel amongst peers.

This channel is implemented using libolm, using XMPP groupchat or JVB channels
as the transport.

Once the secure E2EE channel has been established each participant will generate
a random 32 byte key and exchange it over this channel.

Keys are rotated (well, just re-created at the moment) when a participant joins
or leaves.

Updates strophejs-plugin-stream-management
to 001cf02bef which fixes
few corner cases around XMPP WebSocket reconnect logic.

* fix(safari): override min/max video constraints on safari
Override the constraints on Safari because of the following webkit bug.
https://bugs.webkit.org/show_bug.cgi?id=210932
Camera doesn't start on older macOS versions if min/max constraints are specified.

Needed to be able to return a promise from a test case.

Get rid of the experimental flag for simulcast support, update js-utils for detecting Edge on Android

Switch to using ontrack for remote tracks, re-use mids/transceivers when remote sources are removed and added.

Update strophejs-plugin-stream-management to fix the crash for
the stacktrace above. It happens only with BOSH.
