When TLS-over-FTP is used, the credentials are encrypted. So we must not
wait for the username and the password commands, otherwise we elaborate a
lot of packets for nothing.
Decoding of ipv6 traffic with extension headers was completely broken,
since the beginning of the L4 header was always set to a wrong value.
Handle the ipv6 fragments in the same way as the ipv4 ones: keep the first
one and drop the others.

Zeroing large structures (i.e. size > KB) is quite costly (from a CPU point
of view): we can safely avoid doing that for a couple of big structures.
Standard and Valgrind tests have been diverging quite a lot: it is time
to re-sync them. Use the same script and enable Valgrind via an
enviroment variable:
NDPI_TESTS_VALGRIND=1 ./tests/do.sh
Fix all the warnings.
Getting rid of "-Wno-unused-parameter" is quite complex because some
parameters usage depends on compilation variable (i.e.
`--enable-debug-messages`).
The "-Werror" flag has been added only in Travis builds to avoid
breaking the builds to users using uncommon/untested
OS/compiler/enviroment.
Tested on:
* x86_64; Ubuntu 20.04; gcc 7,8,9,10,11; clang 7,8,9,10,11,12
* x86_64; CentOS 7.7; gcc 4.8.5 (with "--disable-gcrypt" flag)
* Raspberry 4; Debian 10.10; gcc 8.3.0
* Added ARM build and unit test run for SonarCloud-CI.

* Fixed Mingw64 build.
* adapted to SonarCloud-CI workflow
* removed broken and incomplete Windows example (tested on VS2017/VS2019)
* removed unnecessary include (e.g. pthread.h for the library which does not make use of it)

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.
Simplified the process of adding lines to AC_AUTOMATA_t.
Use the ndpi_string_to_automa() function to add patterns with domain names.
For other cases can use ndpi_add_string_value_to_automa().
ac_automata_feature(ac_automa, AC_FEATURE_LC) allows adding
and compare data in a case insensitive manner. For mandatory pattern comparison
from the end of the line, the "ac_pattern.rep.at_end=1" flag is used.
This eliminated unnecessary conversions to lowercase and adding "$" for
end-of-line matching in domain name patterns.
ac_match_handler() has been renamed ac_domain_match_handler() and has been greatly simplified.
ac_domain_match_handler() looks for the template with the highest domain level.
For special cases it is possible to manually specify the domain level.
Added test for checking ambiguous domain names like:
- short.weixin.qq.com is QQ, not Wechat
- instagram.faae1-1.fna.fbcdn.net is Instagram, not Facebook
If you specify a NULL handler when creating the AC_AUTOMATA_t structure,
then a pattern with the maximum length that satisfies the search conditions will be found
(exact match, from the beginning of the string, from the end of the string, or a substring).
Added debugging for ac_automata_search.
To do this, you need to enable debugging globally using ac_automata_enable_debug(1) and
enable debugging in the AC_AUTOMATA_t structure using ac_automata_name("name", AC_FEATURE_DEBUG).
The search will display "name" and a list of matching patterns.
Running "AHO_DEBUG=1 ndpiReader ..." will show the lines that were searched for templates
and which templates were found.
The ac_automata_dump() prototype has been changed. Now it outputs data to a file.
If it is specified as NULL, then the output will be directed to stdout.
If you need to get data as a string, then use open_memstream().
Added the ability to run individual tests via the do.sh script
* RTSP is no subprotocol of HTTP (most of the time)
* detection patterns should stay in rtsp.c
* set detected HTTP protocol only if at least a valid HTTP method detected
