Note that the thread used to handle the participant list messages from
the external signaling server does not change; the EventBus subscriber
mode was "BACKGROUND", but as the message was posted from a WebSocket
handler, which runs in a worker thread rather than in the main thread,
the subscriber was executed in the same thread as the poster.
Also note that the removed "userId" remark was not fully accurate;
although some external signaling messages do actually use "userid" those
currently handled to process the users do not, they always use "userId"
(as documented in the SignalingMessageReceiver).

This will no longer log an error if the room type of the received
message is neither "video" nor "screen". However, that should never
happen, and it would be useful only while debugging, so it is fine to
lose that.
Note that the check is not added to SignalingMessageReceiver itself to
keep it as generic as possible (and due to the low value of adding it as
explained above). Nevertheless, if needed in the future it would be
possible to add a special listener that receives raw messages in order
to validate them and log the errors, if any.

Although "unshareScreen" is technically bound to a specific peer
connection it is instead treated as a general message on the call
participant.
Nevertheless, call participant messages will make possible (at a later
point) to listen to events like "raise hand" or "mute" (which, again,
could be technically bound to a specific peer connection, but at least
for now are treated as a general message on the call participant).

Unlike the WebRtcMessageListener, which is bound to a specific peer
connection, an OfferMessageListener listens to all offer messages, no
matter which peer connection they are bound to. This can be used, for
example, to create a new peer connection when a remote offer for which
there is no previous connection is received.

Eventually all signaling related code should be moved to a Signaling
class that abstracts the differences between the internal and external
signaling servers, including how messages are sent and listened to. In

For now only WebRTC messages can be listened to, although it will be
extended with other kinds later.
This commit only introduces the base class, although it is not used yet
anywhere; a concrete implementation will be added in a following commit.
The test class is named "SignalingMessageReceiverWebRtcTest" rather than
just "SignalingMessageReceiverTest" to have smaller, more manageable
test classes for each listener kind rather than one large test class for
all of them.

The message type is set for all signaling messages. On the other hand,
the payload type is only set for offers and answers (and, if the message
was sent by the Android app, also for candidates). However, in all those
cases the payload type just duplicates the message type, so the message
type can be assigned directly rather than falling back to it if there is
no payload type.

When the HPB is used the signaling messages can be received even when
the local participant is not currently in the call (for example, when
starting the call timed out without other participant joining, or when
reconnecting due to the publisher connection failing). Therefore if the
local participant is not in the call it should not try to establish a
connection with the other participants and disconnect them instead.
Moreover, if the connection is tried to be established when not
in the call the HPB will prevent that, and the PeerConnectionWrapper
will stay in a limbo state waiting for an offer to be sent. If the local
participant then joins the call the PeerConnectionWrapper will already
exist for the other participants, so no new connections will be created,
but those previous connections will never be finally established.
Additionally, as the signaling messages can be received before the join
call response the participant list could be received while the call
state is "RECONNECTING" or "PUBLISHER_FAILED". In those cases, as long
as the local participant is already in the call, the participant list
should be processed as if the call state was already "JOINED" (otherwise
the connections were not established either).
For simplicity the participant list is now ignored only when the call
state is "LEAVING"; this means that the participant list would be also
processed in the "CONNECTION_TIMEOUT" state, but the signaling message
should not be received anyway in that case.

If the call is hung up with a view shutdown (which finishes the
activity) there is no need to do any further processing on the
participant list.
Signed-off-by: Daniel Calviño Sánchez <danxuliu@gmail.com>
When a call is joined the call flags of the local participant change, so
this causes a signaling message to be sent by the server. When the HPB
is used the signaling message is sent through a WebSocket, which is
already connected before joining the call. Therefore, in some cases the
signaling message can be received through the WebSocket even before the
response to the HTTP "joinCall" request.
If there are other participants in the call the call state is changed to
"IN_CONVERSATION" when the signaling message is processed. However, in
the case described above the call state was then set to "JOINED", which
automatically traverses to "CONNECTION_TIMEOUT" if no other call state
was set in 45 seconds. Due to all this the call was joined and the
connections with the other participants were established, but they were
not visible in the UI (although they could be heard) and after 45
seconds the call was left.
To prevent that now the call state is changed to "JOINED" if it was not
already changed to "IN_CONVERSATION" in the meantime.

just refactoring for now. this doesn't solve the bug!
Problem that needs to be solved:
When adding a new Account (User), it is marked as "current", while for the other logged in users "current" must be unset (-> disabled).
The problem is, that for the old active user, "current" is not unset so there were multiple accounts marked as "current".
In the ChooseAccountDialogFragment, only one of the current accounts is shown at the top. Below the set status field, all accounts are listed that are not marked with "current". So as a result, there can be accounts hidden that were marked as "current".

If the notification is canceled, the Activity stops. If the Notification is ongoing and hangup of accept call is clicked, then the notification is canceled (including the ringtone).

Fresco is replaced with Coil everywhere to make it possible to set 'minSdkVersion'
to 23. But Coil is not used directly to avoid splintering the dependency
everywhere in the code. Coil is wrapped by extension functions for 'ImageView'.
Some shared functionality is moved from 'DisplayUtils' into the
'ImageViewExtensions'.
The exisiting initialization of Coil has also be changed. The usage of the self
initialized OKHttp client is removed. If this one is added the
caching of the http client is used by Coil additionally to memory and
disk cache.

When the web socket is abruptly closed it is connected again and the
call is rejoined. However, the call was rejoined in a background thread,
so an exception was thrown when trying to modify the views, which
prevented the call from being joined again.
Besides that the call state needs to be explicitly changed, as if the
web socket was connected again while in a call the state would be
already "JOINED" or "IN_CONVERSATION", which prevents the signaling
settings from being fetched again after the permissions check, and
therefore also prevented the call from being joined again.

The call flags should be checked using bitwise operators; otherwise a
call with phone ("in call | with phone" / "in call + with phone", that
is, "0001 + 1000 = 1001" or "1 + 8 = 9") would be seen as a call with
video ("in call | with video" / "in call + with video",
"0001 + 0100 = 0101" or "1 + 4 = 5"), as "9 >= 5". On the other hand,
using bitwise operators (and only checking against "with video")
succeeds only when the call flags contain "with video" (in the previous
example, "1001 and 0100 = 0000", so it does not succeed).
The "IN_CALL" flag is no longer checked, as "WITH_VIDEO" will be set
only during calls, and therefore checking for "IN_CALL" is not needed.

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 :-)

- 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).

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

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).
