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`

DPI (#1891)
Average values are already printed, but this change should ease to
identify regressions/improvements.

Fix decapsulation of CAPWAP; we are interested only in "real" user data
tunneled via CAPWAP.
When Tcp Segmentation Offload is enabled in the NIC, the received packet
might have 0 as "ip length" in the IPv4 header
(see
https://osqa-ask.wireshark.org/questions/16279/why-are-the-bytes-00-00-but-wireshark-shows-an-ip-total-length-of-2016/)
The effect of these two bugs was that some packets were discarded.
Be sure that flows order is deterministic

No traces and no flows has been removed; only long sessions
has been reduced, keeping only their first packets.
This is quite important in fuzzing systems, since these pcaps are used
as initial seed. There is no value in fuzzing long sessions, because
only the very first packets are really used/processed by nDPI.
Before:
```
du -h tests/pcap/
200M tests/pcap/
```
After:
```
du -h tests/pcap/
98M tests/pcap/
```

These protocols:
* have been addeded in the OpenDPI era
* have never been updated since then
* we don't have any pcap examples [*]
If (and it is a big if...) some of these protocols are still somehow
used and if someone is still interested in them, we can probably
re-add them starting from scratch (because the current detection
rules are probably outdated)
Protocols removed: DIRECT_DOWNLOAD_LINK, APPLEJUICE, DIRECTCONNECT,
OPENFT, FASTTRACK, SHOUTCAST, THUNDER, AYIYA, STEALTHNET, FIESTA,
FLORENSIA, AIMINI, SOPCAST
PPSTREAM dissector works (...) only on UDP.
[*]: with do have an AIMINI test pcap but it was some trivial http
traffic detected only by hostname matching, on domains no more
available...

We already performed exactly these lookups in the generic code to
populate `flow->guessed_protocol_id_by_ip`: use it!
This code probably needs a deeper review, since it is basicaly a simple
matching on ip + port.

Tell "Advertised" ALPN list from "Negotiated" ALPN; the former is
extracted from the CH, the latter from the SH.
Add some entries to the known ALPN list.

These flows are classifed as `LINE_CALL`; another option was
`RTP/LINE_CALL`. No sure about the best solution...
Extend LINE domains list.
Remove RTP dead code.

* Standard support for LINE app
* Added test pcap for LINE app
* make check result for LINE app
* Make check success as 1kxun has LINE packets
* Added the ASN inc file for LINE
* Removed extra lines as its effecting make check
* Editing the SNI required a new pcap output file for TLS.Line format
* Run Configure with --with-pcre --with-maxminddb to enable the generation of h323-overflow.pcap.out
