FPC: add DPI information (#2514)
If the flow is classified (via DPI) after the first packet, we should
use this information as FPC

FPC: small improvements (#2512)
Add printing of fpc_dns statistics and add a general cconfiguration option.
Rework the code to be more generic and ready to handle other logics.

526cf6f291 Zoom: remove "stun_zoom" LRU cache
Since 070a0908b we are able to detect P2P calls directly from the packet
content, without any correlation among flows

Remove "zoom" cache (#2420)
This cache was added in b6b4967aa, when there was no real Zoom support.
With 63f349319, a proper identification of multimedia stream has been
added, making this cache quite useless: any improvements on Zoom
classification should be properly done in Zoom dissector.

Tested for some months with a few 10Gbits links of residential traffic: the
cache pretty much never returned a valid hit.

Fix classification-by-ip in ndpi_detection_giveup (#1981)
Return the "classification-by-ip" as protocol results only if no other
results are available.
In particular, never return something like
"protocol_by_port/protocol_by_ip" (i.e. `NTP/Apple`,
BitTorrent/GoogleCloud`, `Zoom/AWS`) because this kind of classification
is quite confusing, if not plainly wrong.

Notes:
* the information about "classification-by-ip" is always available, so
no information is lost with this change;
* in the unit tests, the previous classifications with confidence
`NDPI_CONFIDENCE_DPI_PARTIAL` were wrong, as noted in #1957

Test multiple ndpiReader configurations (#1931)
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`
