This reverts commit 08f55ccb94.

Add ability to invite users which will use the share sheet or dialog
dynamically.

- re-add thepand icon, shaped like a pill
- round top corners

When the reccorder joins, they have a local participant, which is not rendered,
so don't count it towards the partcipant count used for computing the tile
sizes.

Logs the device list when is updated in the reducer and removes
"button enabled" logging which used to dump the device list, but
in a useless way(Object[Object]).

Makes an attempt to log currently selected device, but because of
multiple possible paths it's impossible to find one reliable spot to log
selected device. One has to rely on device list and the GUM call logged
to figure things out.

Regresssion from bd8a7edbd2.

When the toolbar buttons are overridden with URL parameters, our computed set of
buttons will be wrong. Thus, compute it every time and check for the
differences.

It happens when you are drawing into hidden canvas.

On electron 7 drawing on hidden canvas will trigger a memory leak.
Not appending the canvas for the DOM seems to solve the problem.

This effect doesn't modify the media stream, so its safe to start/stop effect and not apply it on the JitsiLocalTrack. This way we can make sure that this effect is not switched out when presenter effect is applied.

Note that in the usual (vertical) setup, the "toolbar" is just the hide button.

This has the side effect of showing the bottom navbar when the toolbox is open,
which is a nice thing since back is accessible.
