Add (basic) internal stats to the main data structures used by the
library; they might be usefull to check how effective these structures
are.
Add an option to `ndpiReader` to dump them; enabled by default in the
unit tests.
This new option enables/disables dumping of "num dissectors calls"
values, too (see b4cb14ec).

Since e6b332aa, we have proper support for detecting client/server
direction. So Tinc dissector is now able to properly initialize the
cache entry only when needed and not anymore at the SYN time; initializing
that entry for **every** SYN packets was a complete waste of resources.
Since 4896dabb, the various `struct ndpi_call_function_struct`
structures are not more separate objects and therefore comparing them
using only their pointers is bogus: this bug was triggered by this
change because `ndpi_str->callback_buffer_size_tcp_no_payload` is now 0.

Tcp retransmissions should be ignored.
Remove some unused protocol bitmasks.
Update script to download Whatsapp IP list.

Add an helper to exclude a generic protocol
|
|

Skype detection over TCP has been completely disable since 659f75138 (3
years ago!).
Since that logic was too weak anyway, remove it.

We should stop processing a flow if all protocols have been excluded or
if we have already processed too many packets.

If the extra callabck is not set, calling the extra dissection is only a

* Add few scripts to easily update some IPs lists
Some IPs lists should be updated frequently: try to easy the process.
The basic idea is taken from d59fefd0 and a8fe74e5 (for Azure
addresses): one specific .c.inc file and one script for each protocol.
Add the possibility to don't load a specific list.
Rename the old NDPI_PROTOCOL_HOTMAIL id to NDPI_PROTOCOL_MS_OUTLOOK,
to identify Hotmail/Outlook/Exchange flows.
TODO: ipv6
Remove the 9 addresses associated to BitTorrent: they have been added in
e2f21116 but it is not clear why all the traffic to/from these ips
should be classified as BitTorrent.
* Added quotes

As a general rule, the higher the confidence value, the higher the
"reliability/precision" of the classification.
In other words, this new field provides an hint about "how" the flow
classification has been obtained.
For example, the application may want to ignore classification "by-port"
(they are not real DPI classifications, after all) or give a second
glance at flows classified via LRU caches (because of false positives).
Setting only one value for the confidence field is a bit tricky: more
work is probably needed in the next future to tweak/fix/improve the logic.

Improve Microsoft, GMail, Likee, Whatsapp, DisneyPlus and Tiktok
detection.
Add Vimeo, Fuze, Alibaba and Firebase Crashlytics detection.
Try to differentiate between Messenger/Signal standard flows (i.e chat)
and their VOIP (video)calls (like we already do for Whatsapp and
Snapchat).
Add a partial list of some ADS/Tracking stuff.
Fix Cassandra, Radius and GTP false positives.
Fix DNS, Syslog and SIP false negatives.
Improve GTP (sub)classification: differentiate among GTP-U, GTP_C and
GTP_PRIME.
Fix 3 LGTM warnings.

The goal is to have a (roughly) idea about how many packets nDPI needs
to properly classify a flow.
Log this information (and guessed flows number too) during unit tests,
to keep track of improvements/regressions across commits.
