Never show the local participant in the large view unless it's the only
participant.

This fixes 2 issues:

- selecting the local participant when the camera permission wasn't granted
- selecting the other participant when they join a 1-1 call with video muted

* Javadoc introduced @code as a replacement of <code> and <tt> which is
  better aligned with other javadoc tags such as @link. Use it in the
  Java source code. If we switch to Kotlin, then we'll definitely use
  Markdown.

* There are more uses of @code in the JavaScript source code than <tt>
  so use @code for the sake of consistency. Eventually, I'd rather we
  switch to Markdown because it's easier on my eyes.

* Xcode is plain confused by @code and @link. The Internet says that
  Xcode supports the backquote character to denote the beginning and end
  of a string of characters which should be formatted for display as
  code but it doesn't work for me. <tt> is not rendered at all. So use
  the backquote which is rendered itself. Hopefully, if we switch to
  Markdown, then it'll be common between JavaScript and Objective-C
  source code.

Prepare for React 16.

* ref(recording): convert recording label to react

- Create a RecordingLabel component for displaying the current
  recording state, as reflected in the redux store. This is
  needed for 1-on-1 mode to be completely in redux.
- Update the store with the recording state so RecordingLabel
  can update itself.
- Remove previous logic for updating the non-react label, which
  includes event emitting for filmstrip visibility changes,
  as RecordingLabel is hooked into redux updates.

* ref(recording): use status and type constants from lib

* make label really dumb, move logic back to Recording

* 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

The files styles.js are used (pretty much) on React Native only and each
of them exports 1 name. Export it as default to cut down on source code.

We've had Filmstrip & LargeVideo React Components on mobile/React Native
from the start. We didn't have them on Web (because the rewrite in React
is not complete yet). However, that led to differences in the React
Component Conference on Web and mobile. In an effort to get closer to
merging the React Component Conference on Web and mobile, introduce the
React Components Filmstrip & LargeVideo on Web even if a minimal
render-only form at this time.

Until we make a decision on access modifier hints and adopt a respective
coding style, consistency is king.
