to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
Replace calls to builtin functions with macros or functions that call the
Windows-equivalents when targeting windows and call the original
builtin functions everywhere else.
This change makes more parts of libFuzzer buildable with MSVC.

Summary:
Port libFuzzer to windows-msvc.
This patch allows libFuzzer targets to be built and run on Windows, using -fsanitize=fuzzer and/or fsanitize=fuzzer-no-link. It allows these forms of coverage instrumentation to work on Windows as well.
It does not fix all issues, such as those with -fsanitize-coverage=stack-depth, which is not usable on Windows as of this patch.
It also does not fix any libFuzzer integration tests. Nearly all of them fail to compile, fixing them will come in a later patch, so libFuzzer tests are disabled on Windows until them.

This is a fix for bug 37047.
https://bugs.llvm.org/show_bug.cgi?id=37047
Implemented by basically reversing the logic. Previously all strings
were considered, with some operations excluded. Now strings are excluded
by default, and only strings during the CB considered.

By adding a ctor to create fuzzer_allocator<T> from fuzzer_allocator<U>.
This mimics construcotrs of std::allocator<T>.
Without the constructors, some versions of libstdc++ can't compile
`vector<bool, fuzzer_allocator<bool>>`.

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.

Summary:
This code already works and passes some number of tests.
There is need to finish remaining sanitizers to get better coverage.
Many tests fail due to overly long file names of executables (>31).
This is a current shortcoming of the NetBSD 8(beta) kernel, as
certain functions can fail (like retrieving file name of executable).
