fuzz: add fuzzer testing nDPI (initial) configurations (#1830)
The goal of this fuzzer is to test init and deinit of the library, with
different configurations. In details:
* random memory allocation failures, even during init phase
* random `ndpi_init_prefs` parameter of `ndpi_init_detection_module()`
* random LRU caches sizes
* random bitmask of enabled protocols
* random parameters of `ndpi_set_detection_preferences()`
* random initialization of opportunistic TLS
* random load/don't load of configuration files
This new fuzzer is a C++ file, because it uses `FuzzedDataProvider`
class (see
https://github.com/google/fuzzing/blob/master/docs/split-inputs.md).
Note that the (existing) fuzzers need to be linked with C++ compiler
anyway, so this new fuzzer doesn't add any new requirements.
