* build: update m4/ax_pthread.m4 from serial 23 -> serial 31
Update ax_pthread.m4 to the latest version from the autoconf-archive
project.

* build: properly detect AR, CC, RANLIB
It's necessary to be able to override choice of AR/CC/RANLIB and other toolchain
variables/tools for cross-compilation, testing with other toolchains, and
to ensure the compiler chosen by the user is actually used for the build.
Previously, GNU_PREFIX was kind-of used for this but this isn't a standard
variable (at all) and it wasn't applied consistently anyway.
We now use the standard autoconf mechanisms for finding these tools.
(RANLIB is already covered by LT_INIT.)

* build: use $(MAKE)
This ensures that parallel make works correctly, as otherwise, a fresh
make job will be started without the jobserver fd, and hence
not know about its parent, forcing -j1.
* build: respect CPPFLAGS, LDFLAGS
- CPPFLAGS is for the C preprocessor (usually for setting defines)
- LDFLAGS should be placed before objects for certain flags to work
(e.g. -Wl,--as-needed)

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)

* Switched to PKG_CHECK_MODULES to keep pkg-config checks more portable.
