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.
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.
* Add support for Snapchat voip calls
Snapchat multiplexes some of its audio/video real time traffic with QUIC
sessions. The peculiarity of these sessions is that they are Q046 and
don't have any SNI.
* Fix tests with libgcrypt disabled
* Fixed memory leaks caused by conditional free'ing for some TLS connections.
* Members of tls_quic struct should also free'd if the detected master protocol is IMAPS / POPS / SMTPS / etc.

* Prevent reader_util.c from exit()'ing if maximum flow count reached.
This confuses the fuzzer.
* Improved fuzz/Makefile.am to use LDADD for ../example/libndpiReader.a instead of LDFLAGS.
That way, fuzz_ndpi_reader re-links to ../example/libndpiReader.a if something changed there.

Some BSD APIs called in example/ return `struct bpf_timeval`, where nDPI
APIs expect `struct timeval`. These two structs, besides having
a different name, share the exact same set of fields.
