STUN: major code rework (#2116)

Try to have a faster classification, on first packet; use standard extra
dissection data path for sub-classification, metadata extraction and
monitoring.

STUN caches:
* use the proper confidence value
* lookup into the caches only once per flow, after having found a proper
STUN classification

Add identification of Telegram VoIP calls.
