With so many abstractions called conference, I'm not surprised I made a
mistake and my reviewer didn't catch it.

As we are transitioning from remote participants identified by ID alone
to an ID-conference pair, the subsequent commits "Protect against late
PARTICIPANT_JOINED" and "Refine PARTICIPANT_LEFT for ID collisions"
caught the error.

The commit message of "Associate remote participant w/ JitsiConference
(_JOINED)" explains the motivation for this commit.

The plan set in motion here is to associate remote participants with the
JitsiConference instances that created them in order to be able to
remove remote participants when a JitsiConference is no longer the
primary focus of the jitsi-meet app. And that's supposed to alleviate a
problem with multiplying remote thumbnails.

Doing all of the above in a single commit is a bit of a high order. So
I'm splitting the whole into multiple successive commits for the
purposes of observability, comprehension. Each commit is supposed to be
safe even if subsequent commits are not accepted, are reverted,
whatever. Obviously, without the successive commits, a commit may be
"unused".

One of the important pieces of the multiplying remote thumbnails "fix"
offered is removing remote participants who are no longer of interest
i.e. PARTICIPANT_LEFT. But in order for _LEFT to be implemented, _JOINED
must be implemented first.

The feature was not ported to the new toolbar. Arguable these
can all be moved into notification but for now simply the
logic will be removed and worked on again as demand arised.

The flag is always false.

This PR takes The Bulldozer Approach (R): removes the old toolbox and lots of
associated code, though not all of it. Subsequent cleanups will follow.

* deps: update jquery version

* squash: resize thumbnails after appending shared thumb

This forces jquery animate to show the thumbnail somehow...
Remote thumbnails basically work this way (append to filmstrip
and then resize filmstrip thumbnails) so I just copied that
implementation. ... So I admit I lost this fight because
even after looking at jquery I couldn't understand why
it doesn't work on the first resize but does on the second.
Plus I'm being put on a strict timebox to update jquery.

- Modify Etherpad and SharedVideo so their resizing takes into account
  the width of the filmstrip in vertical filmstrip mode.
- Modify Filmstrip's getFilmstripWidth to account for when the filmstrip
  is hidden.
- modify VideoContainer so in vertical filmstrip mode it centers the
  shared desktop stream in the middle of the available space not taken
  by filmstrip.
- Also allow clickthrough on the secondary toolbar itself while still
  allowing clicks on the toolbar's buttons. This allows clicks on
  shared videos to go through.

The YouTube api removed player#getVideoData years ago.
I am completely baffled as to how the feature kept working.
The title of the video is no longer obtainable through
the player itself, so instead call the bot participant
"YouTube."

* ref(notifications): convert some dialogs to error or warning notifications

- Expand the configurability of the Notification component so warnings
  and errors can be displayed.
- Allow Notification to take in arbitrary text for the body.
- Rename defaultTitleKey to titleKey for consistency with descriptionKey.

* ref(notifications): remove openReportDialog method

openReportDialog is a wrapper around showError that adds
a logger statement. It is being called in one place only
so remove the method and have that one place call logger.

* ref(notifications): UI.showTrackNotWorkingDialog takes a boolean

Change UI.showTrackNotWorkingDialog so it takes a boolean
arguments instead of the entire track. A small refactor so
the method needs to know less.

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+.

Create a reference to the jquery element instead of querying for
it globally. This is to better encapsulate the small video
component.

- Re-use the native redux pinning implementation for web
- Remove pinning logic from conference.js
- To the native pinning add a check for sharedVideo so
  youtube videos do not send a pin event
- Add shared videos as a participant to enable pinning and
  so they can eventually get added to the filmstrip
- Emit UIEvents.PINNED_ENDPOINT from middleware

* feat(display-name): convert to React

- Create a new React Component for displaying and updating display
  names on small videos
- The updating of the Component is defined in the parent class
  SmallVideo, which children will get access to through prototype
  copying
- Create a new actionType and middleware so name changes that occur
  in DisplayName can be propogated to outside redux
- Update the local video's DisplayName when a conference is joined
  or else the component may keep an undefined user id

* squash: query for the container, not the el owned by react

- Expose an api on Filmstrip to hide the remote videos container, which does so
  by adding a class
- Modify listeners for user join, leave, share video to call the api
- Hide the container when there is 1 or fewer remote participants
- Always show the container if self view is in focus
- Show the container if the number of remote thumbnails does not match the count
  of remote participants, such as the case of sharing a video

The 1:1 call UI and vertical filmstrip act on remote videos
while leaving local video alone. To facilitate acting only on
remote videos, place remote videos into their own container element.

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.

We used to stop player updates on self presence received, so between stop and self presence we can send a playing update which will provoke adding the video again to other participants.

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.

We pass key which is enough to obtain the title.

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

Only the VideoContainer is interested in showing the video problems
filter which is meant to be displayed when ICE is disconnected.

Adds more analytics events for shortcuts, recording and shared video. Changes the way we calculate ttfm.
