Ryan Macnak afdbce7b13 [vm, isolate] Send large TypedData as ExternalTypedData in isolate messages.
Be careful to free external data when reading or writing a message is interrupted, or releasing messaging without reading on shutdown.

Ryan Macnak 3f40488ec4 [vm, isolate] Refactor isolate message snapshotting to centralize construction of the Message.
Remove unused special case in ApiMessageWriter for lists of int.

This is in preparation for ensuring we always free any external data that ends up in an isolate message.

Regis Crelier 7f57ebcfa1 Remove signature classes from the VM.
They were used as the class of closure instances and as the type class of
function types.
All closure instances now have class _Closure and function types are represented
by a new class FunctionType extending AbstractType.
Fix issue 24567 and add regression test.

John McCutchan 9c4d06a4f2 Make sure that Dart_Ports are printed safely in the service protocol
- A Dart_Port is a random 64-bit integer.
- On 32-bit architectures we were silently truncating the isolate id when printing.
- Parsing in JavaScript would also have issues.

johnmccutchan@google.com 2f7cff7170 Display isolate message queue in Observatory debugger
- Log the parameters to RPCs
- Display messages like stack frames
    - handler function and script visible
    - message preview instead of local variables
- Expanded and previewed messages do not collapse when stepping within the existing message
- Mark patch classes as finalized to avoid ASSERT on class_finalizer.cc:2358 **
- Support iterating over message queues
- Support printing the message queue as JSON
- Inhibit OOB messages from being handled if we are iterating over the message queue
    - avoids dead lock when looking up port handler (done in Dart code with message handler locked) and a stack overflow trigger to handle OOB messages
- make getObject understand message ids
- Fix dartbug.com/23355

ager@google.com 6e945a2578 Optimize the message queue for many active ports with few messages.
The current message queue implementation is very inefficient if you are using
many active ports with few messages. This happens when you use 'call' a lot
on ports which is currently done in dart:io.

This patch does not remove messages from the queue when closing a port. Instead
it drops messages for closed ports when it processes them. This dramatically
speeds up dart:io benchmarks that enqueue tons of writes on a file output
stream.

turnidge@google.com 9d72035ce5 Use the ThreadPool for all isolates and native ports. Previously,
each isolate or native port had a dedicated thread.

Refactored the MessageHandler api...

- Added a Run function to allow a MessageHandler to run on a
  ThreadPool.  These functions take a start and end callback to allow for
  isolate initialization and shutdown.

- Made the queue private to the MessageHandler and moved all message
  processing code inside the MessageHandler (got rid of all of the
  different flavors of RunLoop).  This helps remove some code
  duplication and hides the details of how messages are handled.

- Moved all locking and notification out of MessageQueue and moved it
  up to MessageHandler.  Moved OOB support out of MessageQueue and up
  to MessageHandler.  These changes make the MessageQueue much
  simpler.

- Refactored native port and isolate MessageHandlers to share more code.

- Improved --trace_isolates output.

- Added tests for MessageHandler.

Refactored lib/isolate code...

- Use the new MessageHandler::Run api.

- Got rid of the LongJump stuff in RunIsolate.  No longer needed.

- Use the new StartIsolateScope/SwitchIsolateScope to make the code
  less verbose and less error-prone.

- Store top-level isolate errors in the sticky_error.

Added StartIsolateScope/SwitchIsolateScope classes.

turnidge@google.com 1f5364cd3b Add support for native ports in the vm.
Dart_NewNativePort creates a port associated with a C handler
function.  When messages come in on this port, they are forwarded to
the C function for processing.

To support this, refactored PortMap so that it operates on a new
MessageHandler type instead of directly on Isolates.

For now, native ports have a dedicated single thread.  Eventually we
will back native ports (and possibly Isolates as well) by a shared
thread pool.
