In its current implementation, the VideoStatusLabel shows HD based on peer
connection stats. These stats will be available on temasys browsers soon but
will remain unavailable on Firefox, which does not collect height/width stats.
To support VideoStatusLabel showing cross-browser, move the high-definition
detection out of stat sniffing and instead check the video element itself using
an interval in LargeVideoManager. (An interval was used because the temasys
video object does not support the onresize event.) Also, add a cleanup path from
conference.web to LargeVideoManager to remove the interval.

During the implementation of starting as video muted, a check
was put in place to update the local thumbnail view container's
known local track only if the track was not muted. This can
cause the container to become desynced with the current local
track.(Ideally in the future all state would be in redux so this
manual syncing would not be needed.) Removing the if-muted
check seems to cause no side-effects and makes implementation of
device-switch-while-audio-only a lot simpler because new tracks
can be muted and used immediately.

Move the HD label into the newly renamed VideoStatusLabel
component. That way it cannot be possible for the audio only
label and the HD label to display simultaneously.

Audio only mode can be used to save bandwidth. In this mode local video is muted
and last N is set to 0, thus disabling all remote video.

When this mode is enabled avatars are shown.

We seemed to be using the names "film strip" and "filmstrip" (and,
consequently, their source code-conscious forms such as film-strip,
FilmStrip, etc.) In order to comply with our coding style which requires
a consistent one name for a given abstraction, choose one name and
rename the uses of the other name.

Wikipedia has a definition of a "filmstrip", I couldn't find a "film
strip". I guess our abstraction can be seen as what's described there.
When I google "film strip", I get results about "filmstrip" at the top.
That's why I chose "filmstrip".

Certain uses of "film strip" such as interfaceConfig.filmStripOnly and
in the external API I left untouched in an attempt to preserve
compatibility.

I wasn't sure whether CSS was tangled in compatibility so I made a
choice and renamed there was well.

* Uses new peer connection statuses to check and show different user msgs.

Checks for interrupted state of peer connection and shows appropriate messages. In case of inactive or restoring state a message is show to user that video was stopped on purpose. Removes some unused parameters from the event handlers about peer connection status change.

* Removes isParticipantConnectionActive.

Uses leavingIDs to more efficiently iterate over remote videos.

* Handle last n in the client

* fix(LargeVideoManager.js): Fixes check for low bandwidth. Needs more work

* fix(LargeVideoManager.js): Fixes the Shared Video test.

* fix(LargeVideoManager): Fix shared video view and remove last n checks.

* fix(LargeVideoManager): Fixes jsdoc comment

* fix(RemoteVideo): Fix connection status check

* fix(LargeVideoManager,RemoteVideo): Syntax errors

If we:
 - pin a remote and click it, unpin is signalled.
 - pin a remote and the click another remote, the new one is pinned and signalled.
 - pin a remote and then click local. UI pins local, but unpinning remote is not signaled, fix addressed with this commit.
 - pin/unpin local, nothing is signalled.

It was not switching and staying on local video on unpinning, after change the last shown video will be used to switch to it.

Uses some ES6 syntax. Also removes inputHeight key for resolution as it makes no sence to have dictionary with one key. Removes some code duplication. Makes code consistent: method params for updateLocalStats and updateRemoteStats.

Enable ESLint on jitsi-meet with the same configuration and the same
goals as in lib-jitsi-meet.

When user reconnected and the avatar is displayed we need to perform
full large video update in order to transition correctly.

Grey filter will be applied to the remote video/avatar displayed on
"large" and a message indicating remote connectivity issues will be
shown on top of that.

The message about having connectivity issues should be displayed only
on top of the video like the "video problems filter" is.

It is confusing when the name of the main class exported from the file
is not the same as the filename.

VideoContainer is a separate being which implements the LargeContainer
and it's confusing to have it in the same file. This was encouraging to
access private parts of the VideoContainer directly(not through
the interface).

Moves local video thumb initializations where they belong in the local video constructor. Fixes a problem when there is no video device, then audio levels and gsm bars are missing. We were doing this initializations every time a video device is changed.

There was a bug that the handlers for menuItem for mute and kick are added for all remote participants. When clicked multiple handlers are executed and the action will be executed for all remote participants.
