[Backport] Allow Samsung and Yandex browsers

Check if DOMMatrix exists before cursor coordinate transform

Cursor coordinates are calculated using the presentation SVG object
DOMMatrix. When getting this matrix, some browsers (Firefox at least)
responds it as null if the svg object does not have a visible area.

This adds a check before trying to transform the cursor coordinates
using the matrix inverse so we avoid calling a method from a null object.
If there isn't a DOMMatrix to be used as reference, returns a simple out of
bounds SVGPoint (-1, -1)

Fix share webcam button label for screen readers

Fix the UI state on breakout room audio join

Correctly set audio input/output devices - latest SIP.js version

Users must return their audio to the main room before joining a different one.
Since the audio transfer and the UI state manager doesn't provide a shortcut for
jumping from a breakout room to another, avoid making this opiton available.

When refusing ("thumbs down" button) echo test, user is able to select a different input device. This should work fine for chrome, firefox and safari (once user grants permission when asked by html5client).
For output devices, we depend on setSinkId function, which is enabled by default on current chrome release (2020) but not in Firefox (user needs to enable "setSinkId in about:config page). This implementation is listed as (?) in MDN.
In other words, output device selection should work out of the box for chrome, only.
When selecting an outputDevice, all alert sounds (hangup, screenshare , polling, etc) also goes to the same output device.

Add extra check for sessionToken

Problematic audio in some iOS devices

Patch of improvements for bbb-web

also move this and banned user check to a different method.

This patch includes two improvements made for bbb-web. It tries to better isolate
the sessionToken's handling and session's validation, including logs for each one of
these steps; and removes maxParticipats control from registered users (that are no
longer removed from bbb-web collections) binding it to joined users or users that
reached the enter API call. The following adds more details about this last one:

User's regular flow to join a meeting goes around an API join call -> redis register event ->
redirect to client page -> API enter call -> redis join event. When the guest policy is ASK_MODERATOR,
non-moderators are registered and redirected to a guest lobby that polls for her/his guest status and
only enters the meeting after a moderator approval.
Using registered users as control to check how many participants are in a meeting is problematic because
non-approved guests are counted as participants and bbb-web has to find out when to ditch registered users
records to make a seat in a meeting available again. In other words, a meeting with maxParicipants
of 5 can get it's joins locked with a moderator and 4 waiting guests or bbb-web can wrongly drop a registered
user record on a reconnection inducing weird 401 responses from the API.

This change proposes to control maxParticipants both at join and enter API calls monitoring the number
of redis joined users. This also includes an extra buffer to capture users that called the enter API but
still don't have an user joined event.
User left events are now handled different holding the user data before removing from the joined users collection
and only releasing after verifying that the user didn't reconnected.

Both user left timeout `usersTimeout` and entered user timeout `enteredUsersTimeout` can be configured at properties.

Current sessionDescriptionHandlerModifiers of SIP.js acts before ICE gathering is done. This means we are not able to modify/strip candidates in local SDP.
This modifier acts on local SDP, by allowing user to modify SDP before it is sent on INVITE message.

This considerably changes the way we process audio signaling and start audio elements in user's browser.
We now avoid using AudioContext element for both microphone and listenonly calls, once it is unstable for some iOS devices (cracky audio, user stops hearing audio after a while).
Increased default value for listenOnlyCallTimeout: this avoids activating FreeSWITCH's fallback when ICE negotiation takes longer than 15sec (tested on DO).
Increased listenonly logs.
This fixes #8133 #10388
