When switching to (D)TLS dissector from the STUN one, we need to clear
any flow risks set from the latter (because we don't have anymore
`NDPI_PROTOCOL_STUN` in the classification results)

We are not able to remove custom rules: remove the empty stubs (which
originate from the original OpenDPI code).
`ndpi_guess_protocol_id()` is only called on the first packet of the
flow, so the bitmask `flow->excluded_protocol_bitmask` is always empty,
since we didn't call any dissectors yet.
Move another hash function to the dedicated source file.

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.

Jabber/XMPP is only over TCP (even the name `ndpi_search_jabber_tcp`

as explained here for bitcoin https://www.ntop.org/guides/nDPI/protocols.html#ndpi-protocol-bitcoin
the same is applicable for ethereum.
ethereum detection was removed from mining protocol and is now handled separately.

Try avoiding false positives: look for 3 RTP packets before classifing
the flow as such.
Add a generic function `is_rtp_or_rtcp()` to identify RTP/RTCP packets also
in other dissectors (see 3608ab01b commit message for an example)

For a lot of protocols, reduce the number of packets after which the
protocols dissector gives up.
The values are quite arbitary, tring to not impact on classification

It was the only remaining LRU cache without IPv6 support.

Extend internal unit tests to handle multiple configurations.
As some examples, add tests about:
* disabling some protocols
* disabling Ookla aggressiveness
Every configurations data is stored in a dedicated directory under
`tests\cfgs`
