- introduce CMake flag to enable building fuzzers
- add fuzzers based on LibFuzzer[1] to csv, http_parser and uri modules
[1] https://llvm.org/docs/LibFuzzer.html
Note: LibFuzzer requires Clang compiler
How-To Use:
$ mkdir build && cd build
$ CC=clang CXX=clang++ cmake -DENABLE_FUZZER=ON ..
$ make -j
$ ./Testing/test_csv corpus/ -max_total_time=60*60*60 -workers=4
...
Follows: #1809
