Add comprehensive fuzzing infrastructure for URL parser
This commit adds AFL++ (American Fuzzy Lop) fuzzing support to help find bugs,
crashes, and security vulnerabilities in the URL parser.
Changes:
- Add fuzz_afl.c: AFL++ fuzz target that tests all parser functions
- url_parse() with different flag combinations
- url_parse_ipv4() and url_parse_ipv6()
- url_serialize(), url_percent_decode(), url_remove_white_space()
- Add build_afl.sh: Build script with AFL++ compiler detection
- Add run_afl.sh: Automated fuzzing script with result reporting
- Add url.dict: Dictionary file to guide AFL++ mutations
- Add corpus/: Seed inputs covering various URL patterns
- Basic URLs, IPv4/IPv6, percent-encoding, relative paths
- Edge cases and special schemes (file://, mailto:, etc.)
- Add FUZZING.md: Comprehensive documentation
- Installation instructions
- Quick start guide
- Advanced usage (parallel fuzzing, sanitizers)
- Troubleshooting tips
- Add fuzz.c: Standalone mutation-based fuzzer (no AFL++ required)
- Useful for quick testing without installing AFL++
- Implements various mutation strategies
