[libFuzzer] Add support for Fuchsia OS.
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.
