Right now, using external libgcrypt, nDPI is not linked to libgpg-error
because configure script never checks for it.
```

Make both libgcrypt and libgpg-error mandatory if
`--with-local-libgcrypt` is used.
Technically speaking, libgpg-error might be optional, because it is used
only for debug messages. However having both libraries mandatory
slightly simplified the logic.
In most environments, libgpg-error is a dependency of libgcrypt anyway,
so having both libraries should be the standard case.
* Testing more code in CI environments.
* Added strict option checking for `./configure' in CI environments.

* As there is now a builtin, lightweight libgcrypt
there is no need to disable tls-clho decryption.
* It is still possible to use a host libgcrypt
with `--with-local-libgcrypt'.

* 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)

Addedd macro AM_PROG_CC_C_O in configure.ac, needed to have autogen.sh
manage the error:
C objects in subdir but `AM_PROG_CC_C_O' not in `configure.ac'
Modified case instance in example/ndpi_util.c, since DLT_LINUX_SLL
isn't defined in OpenBSD pcap.h.
- Improved detection code for json-c package to use pkg-config
with custom search path that includes /usr/local
- Added optional option --disable-json-c to disable json-c package for
reducing runtime dependencies.
