turnidge@google.com bd995a345e Avoid trusting the length encoded in the Snapshot if there is an
external length available.  We now pass a length with all messages in
the vm and verify that there is no mismatch with the length from the
Snapshot.

Fixed a bug in the use of ApiMessageReader.  We were always manually
adding Snapshot::kHeaderSize to the data, but neglecting to subtract
kHeaderSize from the message length.

Added FullSnapshotWriter and MessageWriter classes.

turnidge@google.com 2803d78dfd Change the zone allocation api.
Instead of passing a size in bytes to the allocation function, we now
have a templatized Alloc function:

  zone->Alloc<Type>(len)

This is better for security, as we can check for integer overflow in
the size computation before performing the allocation.  Before, we
often failed to check this.

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.

sgjesse@google.com 3481c5661a Decode the Dart message into a Dart_CMessage structure before calling the native port callback
The native port callback is now passed the message as a decodes
Dart_CMessage structure. The Dart_CMessage structure is allocated
in a zone and the callback receiving it should expect the
lifetime to be controlled by the caller.

Added support for zones which do not require a current
isolate. Changed the GrowableArray to support allocating in
aprovided zone instead of the zone for the current isolate.

sgjesse@google.com 42b70dcddb Change the thread interface in runtime/platform and use it starting all threads
The platform thread interface (dart::thread) is now refactored to an
all static interface as suggested by iposva@ and asiva@. Use this
interface for running all threads in the VM.

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.
