d586c2cc28 examples/webrtc: don't use factory_make_full() for enums
They are not currently translated into their respective enum values and
will produce an error.

4ae903d383 webrtc_sendrecv.py: Link pads instead of elements
This was not a problem here because even if we end up accidentally
linking to the wrong pad, things will work out eventually as long as
one pad-added is emitted for each pad that is added.

But it will be a huge problem if someone copies this code and changes
something that requires different handling for different sorts of
pads. The resultant code will be racy. Let's not do this, it's a bad
example.

0007fa38e0 webrtc-sendrecv: Fix create-answer caps negotiation
We need to parse the payload type map provided by the offer SDP and
set those values on the payloader, otherwise webrtcbin will create
a recvonly answer SDP and we won't send anything to the browser.

Fixed it for both C and Python sendrecv examples.

3c0d582b7c webrtc_sendrecv.py: Add picture-id-mode to rtpvp8pay
This doesn't just make TWCC stats perform better, it also fixes
stuttery video playback in Chrome.

583408c312 webrtc_sendrecv.py: Implement all negotiation modes
Earlier, the example only supported one negotiation mode:
* Browser client is running, gstreamer starts a call and sends offer

Now these three modes are also supported:
* Browser client is running, gstreamer starts a call and sends an
  offer request
* gstreamer connects and waits for browser client to start a call and
  send an offer
* gstreamer connects and waits for browser client to start a call and
  send an offer request

The following features are still missing:
* Data channel support
* TWCC support + stats logging

2294356d9b webrtc_sendrecv.py: Fix event loop usage for messages
Instead of creating a new loop, we should just be fetching the running
loop, then doing a blocking network call inside the callback, schedule
it on the event loop. This is what the C example does too.

e453e43e5a webrtc_sendrecv.py: Fix deprecation warning with Python 3.10
asyncio.get_event_loop() will not implicitly create a new event loop
in a future version of Python, so we need to do that explicitly.
