- Added `Dart_SetDartLibrarySourcesKernel` to the Dart embedding API.

`profile_period` has been added to the list of flags which can be

cause the ThreadInterrupter to be shutdown, reinitialized, and started with the

Ryan Macnak 7b9fb893d2 [vm] Add a service method for 'invoke' as the dual to 'eval'.
Refactor the implementation of 'invoke' for sharing between the embedding API, mirrors, and the VM service. The fixes various issues in the embedding API:
 - Dart_Invoke, Dart_GetField and Dart_SetField now generate the same NoSuchMethodErrors as dart:mirrors and ordinary Dart code.
 - Dart_GetField and Dart_SetField now accept a null receiver.
 - Dart_GetField now handles closurization.
 - Dart_Invoke now handles calls through function-typed getters.
In mirrors, it also changes:
 - LibraryMirror.invoke/getField/setField now see members in the export namespace, not just local declarations. I.e., invocation with a LibraryMirror behaves the same ways as invocation against a library prefix in ordinary Dart code.

Moved the responsibility to provide MaxRSS and CurrentRSS from the VM to

The embedder can opt-it by setting a Dart_GetEmbedderInformation
callback using the public Dart_SetEmbedderInformationCallback API.

The implementation of the Dart_GetEmbedderInformation should mandatory
fill the version field and the ones it is able to fill.
The name field must reference a constant C style string, it will not be

Carlo Bernaschina df8bf384eb Introduce external services registration
A new RPC is introduced `_registerService` which allow clients to
register new services that are accessible from all the other clients.

Each registered endpoint is identified by 3 strings:

 - `service`
   a non empty string which identifies the provided service
   (e.g. `HotReload`, `OpenFile`)
 - `alias`
   an alias for that particular endpoint used by clients to identify it
   (e.g. `Flutter`, `IntelliJ`)
 - `method` __generated__
   the RPC method that should be invoked from a client to request it

A new _stream_ `_Service` is introduce, and two related events:

 - `ServiceRegistered`
   which is triggered when a new client is registered.
   All the related information (`service`, `alias`, `method`) are sent.

 - `ServiceUnregistered`
   which is triggered when a client, which previously registered a
   service, disconnects.
   Just `service` and `method` are sent.

- [x] Add `Service` class to dart:developer.
- [x] Add `Service.getInfo` static method to dart:developer.
- [x] Add `Service.controlWebServer` static method to dart:developer.

API:

```dart

/// Information about the service protocol.
class ServiceProtocolInfo {
  /// The major version of the protocol.
  final int majorVersion;
  /// The minor version of the protocol.
  final int minorVersion;
  /// The Uri to access the service. If the web server is not running, this
  /// will be null.
  final Uri serverUri;
}

/// Access information about the service protocol and control the web server.
class Service {
  /// Get information about the service protocol.
  static Future<ServiceProtocolInfo> getInfo();

  /// Control the web server that the service protocol is accessed through.
  static Future<ServiceProtocolInfo> controlWebServer({bool enable: false});
}
```

... and add a randomly generated authentication token path prefix that must be passed in to access the service protocol.

Old base url:

Observatory listening on http://127.0.0.1:54804/

New base url:

Observatory listening on http://127.0.0.1:54804/<token>/

For example:

- Add GrowableServiceIdZone which uses a growable array.
- Unit tests for ServiceIdZones.
- JSONStream has a service id zone.
- Default service id zone is ring with eager id allocation.
- All service RPCs can include a _serviceIdZone parameter.
- Value of _serviceIdZone can be Ring.NewId or Ring.ExistingId.
- All ObjectIdRing usage in object.cc has been replaced with `jsobj.AddServiceId("id", *this);`
- Add a policy for id reuse to ObjectIdRing::GetIdForObject
- ObjectIdRing can dump its contents to JSON.
- Add _dumpRingRequests RPC which dumps the isolate's ring.
- _getCrashDump includes complete object id ring.

turnidge@google.com d9f65329c3 Do not JSON encode the 'result' of a service rpc.
Before a response looked like this...

{ result:<string> id:* }

...where result was always a json encoded string.  This meant that
users of the service protocol had to json decode both the outer
message and the result, which was silly.

Now a response looks like this:

{ result:<map> id:* }

This means that users of the service protocol only need to decode once.

We have changed event formats as well.  Previously, an event looked like this:

{ result:<string> }

(Essentially a result without an id.)  The result was json encoded,
requiring the user to double-decode.

Now an event looks like this:

{ event:<map> }

This allows us to distinguish events from rpc results and avoids
double-decoding.  It also avoids having an id-less rpc result mistaken
for an event.

------------

Some details and associated changes:

- Unify GCEvent and ServiceEvent in the VM.

- Move sequence number handling out of dart code and into JSONStream
  in the VM.  Plumbing.  I needed to do this to avoid double-encoding.
  Some of the dart code gets a bit simpler.

- Update C++ tests to have a sequence number.

- Change format of method/params used in Error responses to be more json-y.

- Strip out double decoding in the service lib.

- Improvements to tests.  I was running into some races and other issues.

- Fail fast when we run into a message decoding problem.  Instead of
  returning a service exception, we now disconnect from the vm.

- VMDisconnected => ConnectionClosed.

- Add some support for a reason string when disconnecting from the vm
  in the service library.
