BaseApp does all the heavy-lifting related to creating the redux store,
navigation, and so on.
App currently handles URL props and actually triggering navigation based on
them.
Unfortunately, as the Jitsi Meet development evolved the routing mechanism
became more complex and thre logic ended up spread across multiple parts of the
codebase, which made it hard to follow and extend.
This change aims to fix that by rewriting the routing logic and centralizing it
in (pretty much) a single place, with no implicit inter-dependencies.
In order to arrive there, however, some extra changes were needed, which were
not caught early enough and are thus part of this change:
- JitsiMeetJS initialization is now synchronous: there is nothing async about
it, and the only async requirement (Temasys support) was lifted. See [0].
- WebRTC support can be detected early: building on top of the above, WebRTC
support can now be detected immediately, so take advantage of this to simplify
how we handle unsupported browsers. See [0].
The new router takes decissions based on the Redux state at the time of
invocation. A route can be represented by either a component or a URl reference,
with the latter taking precedence. On mobile, obviously, there is no concept of
URL reference so routing is based solely on components.

If multiple JitsiMeetView instances are created (not necessarily
existing at once), it's possible to hit a TypeError when reading the
React Component props of the currently mounted App. Anyway, in certain
places we're already protecting against that out of abundance of caution
so it makes no sense to not protect everywhere.
* 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.
