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.

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.)

On Windows `_NativeSocket.nativeWrite` returning to caller does
not mean that the data was flushed into OS buffer. Overlapped
operation might still be in progress - and it will be cancelled
with data loss if we close the handle.
This means _SocketStreamConsumer should take such pending writes
into account and not issue `done` event until pending write
completes.
This change prevents data loss when communicating with
subprocesses on Windows. Previously even doing
`await process.stdin.flush()` would not guarantee data
delivery.

This adds [sendMessage] and [receiveMessage] methods to [RawSocket] class. They are only supported on Linux at the moment as they require connection opened as unix domain socket connection.
This introduces [SocketControlMessage] class that represents a message sent via socket and also introduces [ResourceHandle] class that wraps [RandomAccessFile], [Socket]/[RawSocket]/[RawDatagramSocket], [Stdin]/[Stdout] for
marshalling/unmarshalling purposes.
Underlying OS implementation supports various kinds of control messages that can be passed via sockets, this CL only adds support for sending/receiving opened file description handles.
When receiving a message recipient can attempt to extract handles out of it via [tryExtractHandles]. It returns [null] if message has no handles to extract.

than Linux/Android. So it has not been supported in the initial design.
This cl will enable users to use abstract UDS.
As long as InternetAddress has a path starting with '@', it will be
interpreted as abstract UDS on Linux/Android.
For abstract UDS, checkout unix man page for more information.

Prior to this CL, the signal handler finalizer passes a file descriptor
where a signal number is expected.
This went uncaught for awhile since it is innocuous in most cases.
Clearing a signal handler just involves setting it back to the
default. It is not innocuous where the VM chose to override the
default, for example in the case of SIGPIPE. When setting signal
handlers with the dart:io API, if the finalizer for a _NativeSocket
for a signal handler runs, some time later the VM may be killed by
SIGPIPE instead of getting EPIPE from an IO call.
This CL replaces the call in the finalizer with a new call that
expects a file descriptor, and uses the file descriptor to look
up the signal handler that needs to be cleaned up.

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.

Crashes come from assertion in ReturnTokens() and new_mask() in Eventhandler.
Another issue is when multiple serversockets bind to the same address, Socket will be reused to all Dart_Ports. But Socket didn't keep track of corresponding Dart Port.
When one of isolates is killed, finalizer wakes up and close most recent Dart Port that sends data.
After this cl, Socket may not be reused by different Dart Sockets. All Dart socket will has its own Socket object. But Sockets can have same fd.
This will guarantee finalizer will close right Dart Port.

This allows developers to have more fine grained control over socket
options supported by their platforms, particularly when there is not a
nice way to encapsulate differences between IPv4 and IPv6 options (as
with IP_MULTICAST_IF and IPV6_MULTICAST_IF). It also begins the work
of exposing socket level and option values, although keeping it for now
only to a minimum necessary to assist with setting the multicast
interface for datagram sockets.
This CL also marks `multicastInterface` as deprecated.
