Summary: This patch adds the initial support for Fuchsia. - LIBFUZZER_FUCHSIA is added as an OS type in FuzzerDefs.h - Fuchsia is, by design, not POSIX compliant. However, it does use ELF and supports common POSIX I/O functions. Thus, FuzzerExtFunctions.h and FuzzerIO.h are implemented by extending the header guards in FuzzerExtFunctionsWeak.cpp and FuzzerIOPosix.cpp to include LIBFUZZER_FUCHSIA. - The platform-specific portions of FuzzerUtil.h are implemented by FuzzerUtilFuchsia.cpp, which makes use of exception ports, syscalls, and the launchpad library. - The experimental equivalence server is not currently supported, so FuzzerShmem.h is implemented by stub methods in FuzzerShmemFuchsia.cpp. Any future implementation will likely involve VMOs. Tested with ASAN/SanCov on Fuchsia/x86-64 with the canonical toy fuzzer.
