hausner@google.com 95be46105a Beginnings of a debugger wire protocol 
The debugger wire handler is implemented similarly to the io event handler.
A dedicated thread monitors the debugger port for incoming connection
requests. When a debugger is connected, the VM sends events messages
over the wire and handles debugger requests.

To start the VM with a debugger connection, use the option
--debug:<portnumber>. The VM pauses at the beginning of main()
and waits for a debugger to connect.

Subsequent changes will implement debugger commands one by one.
With this change, the VM only understands "resume" commands.

cshapiro@google.com 3a40c3eec6 Do not externalize Dart strings as C strings for "print()". 
Dart strings with embedded '\0' characters cannot be faithfully
represented as a C string.

This change adds Dart_StringToBytes to the Dart API.  This function
converts a Dart string to array of UTF-8 code units and returns a
length.  Builtin::PrintString now calls Dart_StringToBytes instead of
Dart_StringToCString and, for I/O, fwrite is called instead of fprintf
with the string format specifier.

asiva@google.com 3107319e40 Simplify representation of stack frames. Remove the special types DartFrame/StubFrame and instead use StackFrame with methods IsDartFrame and IsStubFrame for frames representing Dart or Stub Code. This eliminates all the complexity that was added to ensure that we always see only one stub frame before hitting a dart frame during iteration. 
Fixes bug 6380625 which was another case when we had two stub frames before hitting the dart frame.
