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.

It relies on flutter copy of clang distribution, same one that is used to build flutter/engine.
It addressed several deprecated warnings from clang compiler for functions like strdup, unlink, etc.
It allows few warnings still since they are triggered in third_party sources.

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.

When VM starts, it will try to find kernel service snapshot which is located together with exe file. However, if symbolic link is provided, the directory to search will become the parent directory of link but not the actual target.
This cl will resolve the symbolic link to find the kernel service snapshot.

Fuchsia requires the ability to sandbox Isolates w.r.t. file IO.
When a new Isolate starts, Fuchsia will pass the Isolate an object
called a namespace. We can translate the namespace object into a
file descriptor suitable for passing to the *at() family of
POSIX file system calls. The file system calls will then
have visibility only into the specified namespace.
We also plumb Namespaces through on all the other platforms as well to
make the change easier to test and so that in the future we can
implement e.g. per-isolate cwds.
This change adds a new internal class to dart:io called _Namespace,
which is implemented in a patch file. See:
sdk/lib/io/namespace_impl.dart
runtime/bin/namespace_patch.dart
The embedder can set up a non-default namespace by calling
_Namespace._setupNamespace during Isolate setup.
Instances of _Namespace have a native field that holds a pointer
to a native Namespace object. See:
runtime/bin/namespace.h
Calls from e.g. file_impl.dart are now also passed a
_Namespace object. The implementations in e.g. file.cc and
file_linux.cc then extract the namespace, and use it to compute a
file descriptor and path suitable for passing to e.g. openat().

This CL changes File::Write on Windows to call directly to WriteFile()
instead of using _write(). This avoids a number of complexities:
1. Don't need to bother with text vs. binary mode.
2. Don't need to check both errno and GetLastError if _write() fails.
3. Don't need to convert to a wchar_t* for console output since we've
already set the code page to UTF8.

Like HOST_ARCH_*, HOST_OS_* describes the OS the VM is running on, which may be different from the OS the VM is generating code for during AOT compilation.
Currently we conflate the two when emitting AOT as assembly, and we get away with it because Flutter only uses assembly for targeting iOS and one can only target iOS from a Mac, but we expect to use assembly for Android as well so native tools can unwind Dart frames.

This change has two pieces.
- Set the console code page to UTF8.
- This makes strings printed with print() display correctly
- Set the file translation mode to _O_WTEXT when writing to a
stdout or stderr that is connected to a console.
- This makes strings printed with e.g. stdout.writeln()
display correctly.
