* Adds live streaming sound notification.

* Adds ios resources for the new files.

Fixes: https://github.com/jitsi/jitsi-meet/issues/4049

It's an evolution of audio-only mode, where we also allow for receiving a remote
screen-share.

Diving deeper: this basically sets last N to 1 or 0 depending on the
availability of a screen-share.

This prevents inserting any user overridden APP_NAME
values into html. A new translation key is being used
to immediately stop non-english languages from using the
problematic string.

Also tweaked the copy to remove the "eer" and fix
some grammar.

There is no need to display the native app name as
raw html.

This refactors all handling of audio-only and last N to 2 features in preparation
for "low bandwidth mode".

The main motivation to do this is that lastN is a "global" setting so it helps
to have all processing for it in a single place.

i18next.options are initialized before interfaceConfig overwrites are processed which leads to wrong translations.

* ref(feedback): emit api feedback submitted on completion

Compared to firing the event on submission because
the submission ajax will not be completed at that
time..

* squash: update package.json

The filmstrip is currently only hidden when PiP mode is entered. There is no
real reason not to leave the large view as it was.

When a participant is pinned in the UI we then proceed to mark it as selected on
the JVB. This will make the participant part of the last N set and will receive
the highest (or configured highest) video quality.

Pinning a participant at the JVB level just makes sure it will be part of the
last N set.

Since only one participant can be pinned in the UI, there is no point in pinning
it at the JVB level, since selecting it already achieved the same result.

Moves getCurrentConferenceUrl method to base/connection to allow reuse.
The new location is not ideal, but looks the best based on the imports
required (trying to avoid circular dependencies).

* Moves talk while muted as a new feature.

* Adds sound notification for talk while muted.

* Reorder imports and changes the dispatch of the notification.

* Introduces sounds.js for talk while muted.

* Removes unused translations.

* Fixes using translated strings.

* Moves using latest i18next versions and stop using compatibility modes.

* Sorts i18next options.

* Fixes defaultNS used by i18next.

This is used when translating html tags with data-i18n keys as attributes, used by jQuery-Impromptu.

* ref(user-interaction): remove storing of listener

* ref(user-interaction): move browser requirement check to lib-jitsi-meet

* ref(user-interaction): no inner function for listener, use module scope

This only shows up if we cannot prompt again, like when turning permissions off
in the Settings app in iOS.

* Listens for suspend events from jitsi-power-monitor on postis channel.

* Removes duplicated type and actions.

* Moves suspendDetected state from overlay to power-monitor feature.

The confID is domain.com/RoomName or domain.com/tenant/RoomName, adds the tenant if any and also keeps the room name case.

* fix(invite): decode the meeting name

* squash: try to make mobile join same encoded meeting name as web

* Decodes and generated texts for share and copy meeting info.

Decodes in all cases except when it contains a space, as it will generate wrong links when pasted/shared in external applications.
