Liam Appelbe 6bd220f556 Reland "[vm] Fix some Fuchsia tests"
This reverts commit 17faf89d02.

The fix is in eventhandler_fuchsia.cc. Rather than changing the
condition on line 401, I've just weakened the assert.

Zichang Guo ed83a28d3e [dart:io] support Unix domain communications
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.

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().

Zachary Anderson 4b4b8e8783 [Fuchsia] Allows non-regular files to be opened.
Fuchsia has lots of different file types that aren't covered by all of
the things that stat() understands, so we have to switch to
blacklisting directories.

Zachary Anderson 8c9c54d833 [dart:io] Don't close stdin with a socket finalizer
If an Isolate touches the 'stdio' getter, a _NativeSocket with
attached finalizer is created for it. Previously, when such an
Isolate exited, the finalizer would close the underlying
file descriptor. This CL changes the finalizer for stdin such
that the native objects will be cleaned up, but the underlying
file descriptor will not be closed. The underlying file
descriptor will now only be closed if the stdin stream
subscription is explicitly canceled.

Accessing the stdin getter after the stream is explicitly
canceled will result in a FileSystemException.

Zach Anderson 141b6351ba [dart:io][windows] Use WriteFile instead of _write
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.

Ryan Macnak 877284947b Rename TARGET_OS_* to HOST_OS_*.
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.

Zach Anderson bc07953866 [dart:io][windows] Make unicode characters display correctly.
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.
