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

Recording: Skip shapes with missing "thickness" attribute

Not sure what causes this issue, but there's nothing reasonable that can
be done to draw a shape with no thickness. Just skip it.

Perform captions generation in UTF-16 encoding

The indexes returned in recording events from BBB refer to positions
within a UTF-16 encoded string. Rather than attempt to untangle this in
the server (which might have a performance cost), it's easier to switch
the caption processing code to operate in UTF-16 encoding as well to
make it work consistently.

The PyICU library provides a UnicodeString type which is a UTF-16 string
similar to Java and JavaScript, but which supports all the python
indexing methods. It's fairly straightforwards to swap it in in place of
the types used previously, and works natively as an input to the ICU
line break iterator too.

Fix io deadlock in recording scripts process execution utilities

The previous implementation of the BigBlueButton.execute method runs the
process with separate stdout and stderr streams. It first reads all of
the output from stdout, then reads all of the output from stderr.

This can cause a deadlock if the process writes a lot of data to stderr.
The IO buffer for stderr could fill, blocking progress. But since it
hasn't closed stdout, the ruby script is still waiting on a read to
stdout.

Switch to an execution method (using IO.popen) that allows combining
stdout and stderr into a single stream, eliminating the issue.
