* feat(file-sharing): Adds file sharing options.

* squash: Adds missing jsdocs.

* squash: Updates docs for a backend change.

* squash: exports type IFileMetadata.

* fix(conference) Fix different bugs with startMuted policy.
If the user changes mute state after joining the call and before the other participats join the call, make sure those state changes are honored.

* feat(startMuted) Ignore startMuted in Jingle from focus.
Apply startMuted policy based on startMuted setting in room meta data.
Moderator settings and AV moderation settings will now be propagated to new endpoints joining the call through room meta data.
Advertise a new capability 'start-muted-room-metadata' to Jicofo for feature detection.

It doesn't get translated in the TS build, for one.

Script I used:

```python
import os

for (dirpath, dirnames, filenames) in os.walk('.'):
    if '.git' in dirpath:
        continue
    if 'node_modules' in dirpath:
        continue
    if 'dist' in dirpath:
        continue
    if 'types' in dirpath:
        continue
    for filename in filenames:
        path = os.path.join(dirpath, filename)
        if not path.endswith('.js') and not path.endswith('.ts'):
            continue
        #print(path)
        with open(path, 'r+') as f:
            #print(f)
            data = f.read()
            if '__filename' in data:
                p, ext = os.path.splitext(path)
                txt = f"'{p[2:]}'"
                print(txt)
                data = data.replace('__filename', txt)  # Assign the result back to data
                f.seek(0)
                f.write(data)
                f.truncate()
```

- Based off 1.5.0, same as we were using before
- Remove optional dependencies
- Remove unnecessary dependencies

In addition, in this repo:
- Bundle the external plugins we are using as they are single JS files

Jigasi / Jitsi (desktop) seems to encode apostrophes like (&apos or &#39) for
instance.

This is notably visible in the subtitles.

Normalize it so it's plain UTF-8.

* fix(transcriptions): Fixes transcription status, going offline.

* squash: Fixes undefined error.

* ref(SDP) Convert to ES6 class.

* ref(SDP) Use enum for URNs associated with XMPP extensions.

* ref(XMPP) Replace more XEP URN constants with enum.

* fix(RTC) Fixes mediaType lookup based on source-name.

When using bosh and xmpp conference-request (no jiconop on server-side) we can drop av moderation and speaker-stats messages.

This allows us to set defaults through jitsi-meet. Also remove undocumented setting enableJoinAsVisitor that is no longer needed.

* feat: Introduces connection event for custom properties.

Used for shard and region values coming from the backend.

* squash: Update JitsiConnectionEvents.ts

* squash: Update JitsiConnectionEvents.ts

last Index must be set as 0 for each time because of when _parse ConnectionFailed Message triggered twice message will be undefined

It is no longer supported by Jicofo.

* feat(visitors): Fires events for received visitors message promotion request/response.

* squash: Updates logs.

Firefox ESR 115 stops sending REMBs to the bridge under certain network conditions making the bridge suspend all video streams sent to the Firefox eps. It is still unclear why Firefox stops sending REMBs so enabling TCC support as workaround since TCC doesn't seem to have issues with uplink BWE in the older versions.

* ref: Remove PrecallTest.

* ref: Remove callstats support.

Yeah, > 4 years seems like ample time :-)

TCC was disabled on older versions because of a known issue where BWE is halved on every renegotiation. The regular libwebrtc updates in Firefox seems to have fixed it. This hopefully fixes the BWE issues seen on Firefox 117.

With visitors we rarely see not able to send messages or presence because not connected error.
Seems the status of the connection is wrong when quickly disconnecting and connecting again.

* Add a feature flag and xmpp-caps entry for joining as a visitor.

* Default to enabled, use for the confernece-request flag too.

* feat(ssrc-rewriting) Advertise support to Jicofo.

* Fix unit test

* feat(face-landmarks): add timeline

* add duration to xmpp payload

* Remove support for legacy endpoint based signaling and make source-name signaling as the only signaling mode. The legacy screensharing mode will no longer be supported. The client will still be able to process remote presence sent in the old format to support interop with very old mobile clients and jigasi that do not support source-name signaling.
* remove code related to presenter mode.

Instead of Jicofo signaling all the remote sources available in the call, the bridge now signals only a limited set of SSRCs and then rewrites the SSRC on the outgoing media streams. The SSRC mapping is done based on the sources requested by the clients through the receiver constraints. This limits the number of m-lines in the remote/local SDPs on the client and therefore results in better performance in large calls.

* Handle source remapping messages from bridge
* Added track_owner_changed events
* don't process an invalid rtx ssrc.
* keep track of remote ssrcs, only renegotiate on new ones.
* Change source name on remote track on ssrc remapping.
* Don't remove tracks on member leave.
* Remove (orphaned) tracks on session terminated.
* Use serial number (per media type) to create msid attribute.
* Update videoType on remapping.

Avoid needing an external dependency.

They are always required and the signaled features are ignored.

* Add a receiveMultipleVideoStreams flag.

* fix(deployment-info) Prevent error when setting shard and region

* fix

Adds it to deploymentInfo.

* fix(multi-stream-support) Support muting of desktop track.

* fix(multi-stream) Always initiate responder renegotiation even for p2p.
This is needed since the new m-line is always added to the remote description.

* fix(multi-stream) Support multi-stream only on Unfied plan endpoints.

* fix(multi-stream) Advertise source-name signaling to Jicofo when supported.

* fix(JitsiLocalTrack): Remove unnecessary reject.

* fix: add the correct source name attribute for the second video track.

* squash: Address review comments.

Add the _onPrivateMessage handler when breakout_rooms is found in disco info.
