Instead of just giving up try to give as much information as possible
including error code, error returned by Dart_StringFromUtf8 and
ascii portion of the OS error message.
We are making this change because we are getting reports of
ProcessException being thrown with "OS error message was a
not a utf8 string." message. There is no way to reproduce
these situations so instead we are going to add additional
information into the fallback message to aid the investigation.

In order to reduce confusion, if a VM instance detects that it will be
running a dartdev snapshot it will ignore all VM flags and print a
warning message to stderr informing users that the flags are being
ignored and that they should be passed immediately after the 'dart run'
command. This will prevent the dartdev snapshot from being run with
incompatible flags in addition to preventing users from accidentally
setting flags for the dartdev VM when they meant to set those flags for
the target process.
As usual, passing --disable-dart-dev will allow for the user to bypass
this behavior and run their dart program directly.

- Removes the load port functionality from the service isolate, this was
used to load sources in Dart 1 and is pretty much dead code in Dart 2
- Moves resolution of URIs and Package URI (based on package map) to the
individual isolates instead of sending a request to the service isolate
- Setups the package map lazily as it is needed only if resolveURI is
called in Dart code, it is not needed for loading/compiling sources
(this is now done in the front end).
- Removed Dart_ServiceWaitForLoadPort() methods from the Dart C API as
it is not used anywhere.

Given a source file that starts with '#@dill' on a new line, then if the rest of the lines are full paths to the kernel dill files, all kernel dill files will be loaded and executed as single program.
So, for example, given `mytest.dillref` with following content:
```
/projects/mytest/build/bin/main.vm.dill
/projects/mytest/build/packages/mytest/lib.vm.dill
```
invocation of `dart mytest.dillref` will result in loading two dill files and starting combined app.

Fuchsia's Dart and Flutter content handlers share the implementation of
dart:io with the command line embedder, but would like to disable
some operations that don't make sense for them, like exiting thoe whole
process, which may be hosting multiple unrelated Isolates.

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().
