turnidge@google.com c48496b873 Refactor isolate startup code in preparation for making isolate spawning more truly non-blocking. 
Instead of passing a startup message to the new isolate, pass all
necessary information in to _startIsolate directly.  The new isolate
sends its control port and capabilities back to the parent.

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.
