ParticipantDisplayItems are not associated to a full participant but to
each of the single connections that the participant may have (video and
screen). However, when they are added to the map only the session ID is
used as key. Due to this when a participant starts a screen share the
ParticipantDisplayItem for the screen share overwrites the item for the
video, and once the screen share is stopped the old item is not
restored. Moreover, if a participant is already sharing a screen when
the local participant joins whether the video or the screen share is
shown is undefined and depends on which connection is established first.
To solve that the ParticipantDisplayItems are now associated with both
the session ID and the video stream type ("video" or "screen"). Due to
this both the video and the screen share of the remote participant are
shown in the grid view; in the future it might be better to only show
the screen share, or allow switching between screen share and video, or
show the screen share in full screen and hide the grid... but for now,
as a quick fix, this is good enough :-)

this didn't make sense because time between firebase and devices is not synchronized, so the results were useless.

- add missed call notifications in NotificationWorker and CallNotificationActivity
- introduce refactoring of Notification handling (isolate firebase stuff from other logic). All "UI-notification" logic from ChatAndCallMessagingService was moved to NotificationWorker. ChatAndCallMessagingService was renamed to NCFirebaseMessagingService because it is now only responsible for firebase stuff. This separation should make it easier for alternative push services to dock with the app (if they are incorporated in the future).
- for DEBUG mode: show delivery delay time in notifications (time between sending from firebase to receive on device).

When pulling signaling messages failed the source observable was
immediately subscribed again, which immediately triggered another pull.
Rather than hammering the server or a flaky network with new requests
again and again now further requests are performed with an incremental
delay (up to 16 seconds).
The delay is increased only when several requests fail in a row, and it
is reset as soon as a request succeeds.

When the internal signaling server is used the observable to pull
signaling messages is subscribed again after each completion, but in
case of an error it was retried only 3 times. Those 3 times are not in a
row, though, but in total for the whole observable, no matter how many
times it was subscribed again.
Due to the limitation on retries in a long call with a flaky connection
pulling the signaling messages could fail more than 3 times, which
caused the observable to finish with an error and therefore stop further
pullings. In this situation the Android app would not notice if other
participants joined or left the call, and thus it would not establish a
connection with them or stop it. To prevent that now the number of
retries is unlimited (although the retry is still stopped if the local
participant is no longer in the call).

The URL for the avatar depends on whether the call participant is a user
or a guest and, if it is a guest, on its nick. Although the user id of a
participant does not change if the participant is a guest the nick may
be changed during a call, so the avatar URL needs to be updated as well.
As the avatar URL is fully derived from other properties it is now
calculated internally in the ParticipantDisplayItem and calculated when
any of the properties it depends on changes (also for the user id for
completeness, as technically the item could be reused for a different
participant with a different user id, even if it is not currently done).

The new sessions are computed by substracting the old sessions (those
for which a PeerConnectionWrapper exists) from the sessions currently in
the call. However, when "oldSessions" was used for that it no longer
contained the old sessions, it only contained the sessions which were no
longer in the call. As those sessions are mutually exclusive with the
sessions currently in the call nothing was substracted from
"newSessions", and it ended being the sessions currently in the call
instead.
When the HPB is not used the list of participants in the conversation is
periodically updated every 30 seconds if no other signaling message was
received in the meantime. As the layout for a participant overrides any
previous layout for that participant this periodically reset the layout
of all participants in the call, as they were all treated as new
sessions.
When the HPB is used the list of participants in the conversation is
updated only when something changed. However, similarly to the previous
case, when that happens the layout of all participants in the call is
also reset for the same reason.
To solve that now "oldSessions" is not modified, so it contains the
sessions for which a PeerConnectionWrapper exists, and substracting it
from "newSessions" now gives only the new sessions.
The other usages of "newSessions" besides creating the connection and
setting up the layout, that is, getting the peers in the call and
changing the call status to "In conversation", should be safe if
executed only when there are new sessions rather than when there are
participants in the call but they did not change.

The old sessions are used to know which connections need to be ended
because they are no longer in the call. However, if a participant is no
longer in the call but there was no connection yet then there is no
connection that needs to be ended; any existing connection will be added
when looping through the connection list, and if it needs to be stopped
it will be found when substracting the sessions that are currently in
the call.
The old sessions are also used to find the new sessions in the call. Due
to an issue in how that is computed "newSessions" currently store the
sessions in the call rather than only the new sessions (this will be
addressed in a following commit). Nevertheless, in both cases any
session not in the call for which there is no connection either will not
make any difference in the computed "newSessions" (as they are mutually
exclusive, so they will never be removed from "newSessions" when
substracting the old sessions).
Due to all that it is not needed to store sessions not in call as old
sessions / sessions to end.

This should avoid that the capabilities not available for the server EOL
check in 'ConversationListController#onAttach'.
Missing capabilites can also have an impact on multiple actions, but the
server EOL check is the first one.

When a new participant is found and the layout for that participant is
set up the participant data might have not been fetched yet. If that
happens the user ID can not be got from the data and therefore a guest
avatar would be shown for that participant, even if that participant is
a normal user.
However, the signaling message that is used to find new participants
already includes the user ID, so it is now explicitly given and, if not,
then it is got from the participant data (which is needed when handling
the establishment of a connection, as in that case the event does not
contain the user ID).

When setting the participant layout, if the HPB is not used, the user ID
is got from the participant list data fetched when a new participant is
found. However, as the participant layout is setup as soon as a new
participant is found the data may have not been received yet, which
ended in a crash (NullPointerException). Now the access to the
participant object is guarded to prevent that.

Fresco is replaced with Coil verywhere. But Coil is not used directly to
avoid splintering the dependency everywhere in the code. Coil is wrapped
by extension functions for 'ImageView'.

Now the 'can ignore lobby' permission is respected.
The 'ChatController' has now a property of the type
'ParticipantPermissions' because it's needed multiple times. The
property will be updated in 'ChatController#getRoomInfo' if the
conversation is protected by a lobby.
The function 'Conversation#shouldShowLobby' is removed in this commit.
'Conversation' is a pure model class to hold the plain JSON response.
The logic is moved into the already existing function 'ChatController#shouldShowLobby'.
