Add frontend for fuzzing
Use the following configure command: $ ./configure --with-fuzzer --with-fuzzer-lib=/path/to/libFuzzer.a \ CC=clang CXX=clang++ Places an irssi-fuzz in src/fe-fuzz/ after build. Also can specify SANFLAGS to override the chosen sanitizer flags (defaults to "-g -fsanitize=address -fsanitize-coverage=trace-pc-guard").
