Basic support for Unix domain sockets on Windows within
the limitations of the operating system itself: no
support for abstract addresses, datagram or
packet sockets and ancillary data.
This also fixes File::GetType on Windows to correctly
identify reparse points representing AF_UNIX sockets
as such, rather then identify them as links.
Finally, it is worth noting that there is an existing
discrepancy between POSIX OSes and Windows: on POSIX OSes
File(sockPath).existsSync() returns true, but on Windows the
same code returns false because Unix domain sockets are not
considered regular files by stat.
This CL does a bunch of refactoring around RawAddr class which
surves as a wrapper around various structures in sockaddr_* family.
Distinguishing anonymous AF_UNIX address from abstract AF_UNIX
address requires passing around the length of the address
structure. Thus we incorporate this information into
RawAddr. This will also make possible to properly support
full-range of abstract AF_UNIX addresses in the future because
supporting these requires properly handling embedded NUL bytes.
(See https://github.com/dart-lang/sdk/issues/46158).

* Fix `ToWinAPIFilePath` handling of UNC paths. This function did
not handle UNC paths correctly: it was prefixing them with
`\\?\` instead of `\\?\UNC\`;
* Fix issue in `File::Copy` forcing the wrong path to long form:
temporary files are created next to the destination, so it
is destination (`new_path`) that should be forced into long form and
not the source;
* Fix issue in `GetDirectoryPath` not preserving the path separator.
The newly added test should cover all these corner cases to prevent
future regressions.

When uploading CLs, the presubmit checks verify that the lines in the
diff are formatted correctly according to `git cl format runtime`.
However, when `buildtools/<os>-<arch>/clang/bin/clang-format` is
updated, it does not force reformatting of files that would be
reformatted.
This leads to two issues:
* Inconsistent style within the code base and within a single file.
* Spurious reformatting in CLs when (1) clang-format is used on the
whole file, or (2) the diff lines overlap.
`clang-format` doesn't change that frequently, so in general this is
not a large issue, but I've seen a bit too many "spurious formatting,
please revert" comments on CLs recently.
This CL formats the runtime to be in line with the current pinned
`clang-format`:
```
$ find runtime/ -iname *.h -o -iname *.cc | xargs buildtools/mac-arm64/clang/bin/clang-format -i
```
`git cl format` (which only formats changed lines, and does so with
`clang-format`) seems to not agree with itself, or clang-format, or
cpplint in a handful of places. This CL adds `// clang-format off`
for these. (See previous patchsets for the specific instances.)

* Switch to `std::unique_ptr<wchar_t[]>` to represent a

`StringRAII` and `Utf8ToWideScope`;
* Avoid back and forth conversion between UTF8 and UTF16:
convert to UTF16 first then work on that. This also simplifies
code - previously it tried to work with strings allocated in
different ways uniformly, which is actually unnecessary if
resulting string needs to be converted to UTF16 (and allocated
with `malloc`) anyway;
* Fix a bug in `File::CreateLink`: it was handling relative
links with long paths incorrectly. Change file_long_path_test
to cover this case and make it run on non-Windows systems as

Upstreamed changes from cl/579854752.
The cross-compiler checks some things that are check on Windows.
* Correct capitalization of filenames in includes.
* Field initialization order in constructors.
In the cross compilation process, some binaries are run on the host.
This unveiled missing `UnwindingRecords::GenerateRecordsInto`.
Finally, when emitting blob data with a symbol in assembly, the
`.type` directive is not supported but the format should still be
unix style assemble. So this CL introduces "win_gnu". This tool is
directly invoked from the build-rules in cl/579854752, and will not be

This is a reland of 391d3bcdd8
The root cause of the failure is that the destination path uses forward
slashes as path separator.
This fix checks for forward slashes as a potential path separators.
If both forward and back slashes exist, the one closer to the end of the
path will be used to get the destination directory.
If any step fails, it will fall back to original copy.

Support Unix domain sockets communication on Linux, MacOS and Android.
Changes:
1. Add a field for InternetAddressType named unix.
2. Constructor of InternetAddress gains one more optional field: type. InternetAddress(String address, {InternetAddressType type});
3. Add another constructor to InternetAddress which taks raw address/path for ip/unix addresses as an argument. InternetAddress.fromRawAddress(Uint8List rawAddress, {InternetAddressType type});
The operation for unix domain sockets communication is basically the same as normal sockets except an InternetAddress with type unix should be passed.
