It's been considered too disruptive and will often misfire especially
if there are issues with the data channels.

* ref(web): removes video blur when ICE is disconnected.

Removes the blur effect from the large video and stops showing
the network connectivity issues message when ICE disconnects.

The feature has been considered too disruptive and there's a plan to
have it replaced with a more subtle indication.

* remove RECONNECTING key from main.json

* ref(Filmstrip): Optimize resizes.

* fix(thumbnails): resize.

* fix(thumbnails): Issue with height 0, width 0.

* doc(Filmstrip): Improve JSDoc.

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.

When a fade in/out animation is in progress, another large
video update can be queued but can try to force itself onto
large video. For example a pin can be in progress and while
the fade in/out animation plays, local video can change its
video type during the animation and forcing an update of
large video. This results in local video getting forcible
updated onto large video while the pinned video is left on
small video only.

* fix(large-video): do not show avatar if no url

By default the large video dominant speaker avatar
has an empty src, which will result in a broken
image displaying. There is also disconnect with
non-react code trying to set an undefined src.
To prevent such until local avatar generation
work is done in the future, just don't show the
avatar.

* fix(conference): set the room instance earlier

Set the room instance on APP.conference before triggering
a redux update of the conference being set,, because
middleware can then fire and call methods on APP.conference
that depend on the room being set.

* get local participant directly from store instead of from global

- Reset some state on the singletons conference
  and VideoLayout.
- Add a way for LocalVideo to clean itself up
  by sharing logic with the other SmallVideos.
- Add clearing of chat messages so they don't
  linger.
- Remove some UI event listeners.

Instead of using JS, just use CSS 100% width and height. This
also resolves a jitter that occurs on edge when a modal's
container appends to the body.

* fix(PresenceLabel): Use translated strings for the presence label.

* feat(sounds): Implements loop and stop functionality.

* feat(invite): Add ringtones.

* fix(invite): Code style issues.

This reverts commit 88325aeef2.
Turns out a conference with a password triggers a failed conference
join. It's going to be tricky to decipher when to do actual
cleanup, and where to shove that code, so reverting is easier for
now.

Destroy local tracks and also destroy large video so the
user does not wonder why camera (and mic) are still enabled
even though hangup has been pressed.

* ref(avatars): remove Avatar.js

- Rely on redux getting updated with new participant state
and any calls to getAvatarURL passing in the redux
participant state. This way the state within Avatar.js can
be removed.
- Clean up methods on UI.js. Because all state is in the
store, separate methods for updating the avatar aren't as
necessary. Instead centralize accessing of the avatar for
components outside of redux and centralize the call to
update avatars for non-react components.
- Controversial: cache a participant's avatarURL on the
participant state. Currently the participant's avatarURL
that is generated without jwt (which sets the avatarURL directly)
is not cached. Without cache, there can be many redundant
calls to APP.API.notifyAvatarChanged.

* Leverage middleware timing to diff avatars

One alternative implementation is to leverage middleware's
ability to intercept updates before and after redux has
upated and then compare avatarURLs.

* kill UI.getAvatarUrl

* profile button sets its own avatar url (solves update timing)

* remove calls to updating avatar outside of middleware

* update UI.js doc

* remove left over logic from initial implementation

* try to move local user fallback into selector func

* default to id 'local' in selector

ESLint 4.8.0 discovers a lot of error related to formatting. While I
tried to fix as many of them as possible, a portion of them actually go
against our coding style. In such a case, I've disabled the indent rule
which effectively leaves it as it was before ESLint 4.8.0.

Additionally, remove jshint because it's becoming a nuisance with its
lack of understanding of ES2015+.

* feat(quality-slider): initial implementation

- Add new menu button with an Inline Dialog slider for
  selecting received video quality.
- Place P2P status in redux store for the Inline Dialog
  to display a warning about not respecting video quality
  selection.
- Respond to data channel open events by setting receive
  video quality. This is for lonely call cases where a
  setting is set before the data channel is open.
- Remove dropdown menu from video status label and clean
  up related js and css.

* first pass at addressing feedback

- Move VideoStatusLabel to video-quality directory.
- Rename VideoStatusLabel to VideoQualityLabel.
- Open VideoQualitydialog from VideoQualityLabel.
- New CSS for making VideoQualityLabel display properly.
- Do not render VideoQualityLabel in filmstrip only instead of hiding with css.
- Remove tooltip from VideoQualityLabel.
- Show LD, SD, HD labels in VideoQualityLabel.
- Remove action SET_LARGE_VIDEO_HD_STATUS from conference.
- Create new action UPDATE_KNOWN_LARGE_VIDEO_RESOLUTION in large-video.
- Move VideoQualityButton into video-quality directory.
- General renaming (medium -> standard, menu -> dialog).
- Render P2P message between title and slider.
- Add padding to slider for displacement caused by P2P message's new placement.
- Fix display issue with VideoQualityButton displaying out of line in the
  primary toolbar.

* second pass at addressing feedback

- Fix p2p inline message color
- Force labels to break on words
- Resolve rebase issues, including only dispatching quality
  update on change. Before there was double calling of dispatch
  produced by an IE11 workaround. This breaks now when setting
  audio only mode to true twice.
- Rename some instances of quality to definition

* rename to data channel opened

* do not show p2p in audio only

* stop toggle audio only icon automatically

* remove fixme about toolbar button

* find closest resolution for label

* toggle dialog on button click

* redo last commit for both button and label

* feat(presence): display status in thumbnail and large video

- Create a React Component for displaying presence. It currently
  connects to the store for participant updates but in the future
  should not be as smart once more reactification occurs.
- Modify filmstrip css so the presence status displays horizontal
  center and below the avatar.
- Modify videolayout css so the presence status displays horizontal
  centered and with a rounded background.
- Dispatch presence updates so the participant state can be update.
- Update message position on large video update to ensure message
  positioning is correct.

* squash: do not show presence message if connection message is displayed

Remove duplication and direct access to kind of private 'state' field by
introducing 'getCurrentContainer' method.

The container needs to store user's ID in order for the 'isOnLargeVideo'
logic to work correctly when user has no stream (previously it was
obtained from stream which can be null/undefined).

'_isConnectionActive' is not used anymore

The default for 'show' argument of 'showRemoteConnectionMessage' is
undefined (unspecified).

Simplify 'updateParticipantConnStatusIndication' by getting rid of
'showMessage' argument.

Add ninja icon which wil be displayed when user's connection status is
inactive.

Apply grey filter only for interrupted state.

Do not use isLastN directly, but check ParticipantConnectionStatus.

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.

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.

* 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.

* 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

Recently, we reimplemented the watermarks in React. Unfortunately, we
didn't take into account film strip-only mode.

Additionally, we duplicated watermark-related source code on the Welcome
and Conference pages.

The "data-i18n-options" attribute value is stored in jQuery cache and
at the time when i18-next tries to access it to do the translation
it gets the old value from the cache and the message is not updated
correctly. Passing the "msgOptions" explicitly to "translateElement"
fixes the problem by avoiding jQuery cache.

Removing translateString forces using data-i18n attributes, to make sure we do not forget to set them. Missing data-i18n attributes is a problem with late loading where we can end up without translation, without text. Missing data-i18n attributes is also problem that strings will not be translated when changing language.
Fixes a bug in invite dialog, where remove password button was shown for non moderators.

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