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.

If ping timeouts two times in a row (25 seconds total)
the XMPP WebSocket connection will be killed and restarted.

There's a plan for using ping to detect XMPP WebSocket
disconnected instead of waiting for timeouts on the network layer.

This also simplifies ICE failed handling logic.

* ref: Moves xmpp logs to be accessed from connection.

In cases where there is no room like pre-join and lobby screen we still want to be able to debug xmpp messages.

* squash: Remove getLogs from Conference.

* squash: Fix catch.

* squash: Print the error.

The same logic should apply to all Chromium based browsers, not just Chrome.

This is useful for testing insertable streams related issues.

* ref: Fix imports order.

* feat: Adds display name required connection event.

There are cases when using tenants subdomain) where we would pass a capital letters in the muc component.

* Initial impl of lobby rooms.

* Fixes tests to check the new fulljid added to MUC_MEMBER_JOINED.

* Updates few of the comments, renaming some functions.

* Renames disableLobby ChatRoom option to enableLobby.

* Fixes a comment.

* Moves setMembersOnly method to ChatRoom.

* Fixes counting members, to exclude jicofo.

* Moves setLobbyRoomJid earlier and renames a method.

Rename _maybeEnableDisable to maybeJoinLeaveLobbyRoom.

* Drops using custom roomconfig lobbypassword field and reuse room lock.

* Handles destroying the lobby room.

* Handles clear lobby room on destroy for moderators.

We do not try to leave the lobby room as it is server-side destroyed and we handle that. The only case of leaving a lobby room is when request to join room is being approved.

* Join main room if lobby is disabled while waiting.

* Adds MEMBERS_ONLY_CHANGED conference event.

* fix: Make sure we leave lobby if main room is joined.

* fix: Setting password when joining locked room.

* fix: Fixes case where we enable lobby for already locked room.

* fix: Fixes case where we enable lobby and then lock room.

* fix: Fixes lint.

* ref: Removes shared password for lobby.

This functionality is handled by the lock room password and handled there.
Removes duplication and unnecessary complicated API for lobby room.

* fix: Fixes comments.

Add RFC 4588 to the list of advertised features on Firefox.
Use RtxModifier only for cases when simulcast is achieved through SDP munging
This will ensure that RTX is negotiated whenever it is offered by the browser.

If user experiences any failed reconnect during the entire
session, even if followed by a success, then
the "connectionFailed" flag will trigger
JitsiConnectionEvents.CONNECTION_FAILED on hang up while
processing the disconnected transition.

The LipSyncHack is currently broken in Jicofo and
will lead to unstable behavior.

Prevents from calling disconnect on the Strophe
connection if it already has been called or
not connected.

Websocket keep alive is HTTP GET request sent on the service URL passed
to Strophe. It is used to keep the stick tables alive. The feature comes
in enabled by default whenever Websocket are used. Pass
'websocketKeepAlive' config option set to -1 to disable.

See the code for more details about the default interval value.

If Strophe goes to the ERROR state it will pass the error message there
and then transition to the DISCONNECTED state, but without any error
msg.

All calls to connection.send should go through the wrapper in order to
prevent breaking the connection by calling it in the not connected
state.

This prevents from accessing Strophe internals directly and allows to
block 'send' calls while disconnected. The latter breaks the stream
resume logic by putting stanzas onto the send queue.

TODO make jitsi strophe plugins use the XmppConnection wrapper whenever
possible instead of interacting with the Strophe.Connection directly.

Websocket sends queued presence 'unavailable' and the stream close
message correctly when the connection is being closed.

This way it's easier to figure out which parts of the disconnect method are about
cleaning up the connection and the reasons on why it's important can be put in
the JDoc of this method.

...it make it easier to process the logs in automated way.

It can either be a websocket or bosh URL, so the current naming is
confusing.

* Fix URL for sendBeacon.

* Performs sendBeacon once or connection.disconnect().

Move time since last success error detail to
the _getConnectionFailedReasonDetails method and use it on all
connection failed events.

This functionality is being brought back for apps
that use ljm for its prosody logic but not for
video conferencing, ie Jitsi-Meet Spot. The desired
use is for Spot-TVs to be identifiable by their
jid alone and for the resource to be the part
that identifies them.

* Always uses 8 hex digits for the MUC nickname/endpoint ID.

* squash: Fix a comment and add the full JID to the log.

* squash: Fixes the compilation and style.

Add 'timeSinceLastSuccess' to the details of connection dropped event.

* feat(screenshare): support remote wireless screenshare

- ProxyConnectionService is exposed and meant to be the
  facade for creating and updating a peer connection with
  another peer, outside of the muc.
- ProxyConnectionPC wraps JingleSessionPC so the peer
  connection handling can be reused.

* attempt to make more configurable

Fixes tests.

Updates speakers stats with values received by the spealerstats component, all the logic is activate only in case we discover speakerstats component address from disco-info and the incoming message is coming from that component.

When the main domain advertises component with type 'speakerstats' every participant will send message to the component with the name of the room where this happen.

User may decide to abort the connection while it's stuck at connecting.

* Adds new parameter details for the connection failed event.

Adds suspend and shard_changed details.

* Updates the used strophejs version in dependencies.

* Updates the used strophejs version in dependencies (package-lock file).

* Changes to always report suspend time, reports 0 on no suspend detected.

* Updates the used strophejs version in dependencies (1.2.14-1).

* Changes details field name.

In order to include browser capabilities in RTCBrowserType I needed to
refactor RTCBrowserType.

Strophe's builtin retry mechanism uses exponential backoff, and 5 retries
results in a very long time.
