Zachary Anderson d0295c873c [dart:io] Namespaces for file IO 
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().

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.

Zachary Anderson 7308e58c3f Really remove io support when dart:io is unsupported. 
Previously we would compile in implementaitions of native calls for
IO functions that would never be used. This CL provides implementations
that throw a Dart exception if they're called by mistake. It also uses
a DART_IO_DISABLED preprocessor define to clean up the build files and
check that we're not including code we shouldn't.

and not used on Windwsm. Removed and call directly to FDUtils when needed.

In Socket::Accept setting close on exec was missing on OS X and Android.

ajohnsen@google.com 79cf8dc61f Don't report file-system move events on Mac OS, and use no-defer to avoid past events. 
Mac OS does not have a proper way to report 'from' and 'to', thus making it impossible to reason the move direction, as other events may shuffle the order, events are received in.
