* Fix ICE connection fallback
Short connection detection relied on iceFailedTimeout, which previously
had been misinterpreted. Since we've reduced iceFailedTimeout, it is
creating false negatives.
We'll instead use PingTimeout since clients are expected to keep the
signal connection active.
* reduce ping interval to align with total ice failure timeout
There are cases that experience the signalling channel timeout
and disconnect and there are no logs of what the state of ICE at all.
Log ICE candidates when closing transport so that there is some
visibility in those cases.

Logging expected WS close at Infow to understand reasons for closure.
Moving "read from ws" to Debugw as it happens when signalling closes.
Also filter out a data channel abort chunk log as it shows a bunch of
errors, but those are expected though.
It's been reported that "ghost" participants, those that did not terminate
cleanly, hang around the room for too long after they disappear.
Evaluating our timeouts a bit, it seems that we are really conservative
in waiting for participants to disconnect. This PR cuts down the disconnect
timeout from 50s to 20s, a 30s reduction.
* Split RTPStats into receiver and sender.
For receiver, short types are input and need to calculate extended type.
For sender (subscriber), it can operate only in extended type.
This makes the subscriber side a little simpler and should make it more
efficient as it can do simple comparisons in extended type space.
There was also an issue with subscriber using shorter type and
calculating extended type. When subscriber starts after the publisher
has already rolled over in sequence number OR timestamp, when
subsequent publisher side sender reports are used to adjust subscriber
time stamps, they were out of whack. Using extended type on subscriber
does not face that.
* fix test
* extended types from sequencer
* log
* Fix time stamp adjustment when starting with dmummy packets.
- Populated extended values in ExtPacket on dummy packet.
- Have to pass reference time stamp offset to first packet time
adjustment.
* display participant version info
* Add option to issue full reconnect on data channel error.
There are situations where send data packet fails because of "stream
closed". It is unclear when that happens. Seems to be after an
ICERestart after ICE failed and connection type switching to TURN
from ICE.
Once the failure happens, it is not recoverable. Potentially, it is
recoverable, but unclear where the problem lies. Attempts to reproduce
looking at the pattern of failures has been unsuccesful.
In the mean time, adding an option to issue full reconnect
when send data packet fails.
* typo
If room metadata is changed in between when a participant is joining and
when they've became active, that participant will not have the latest
room metadata.
