When the debugger agent terminates the used port can be stuck in TIME_WAIT for some time depending on the OS and the state of the socket. With this change will allow the debug agent to start listening on a port still in TIME_WAIT. During development of both V8 and embedding applications this makes it much easier to restart an application using the debugger agent.
This also makes it possible to run the tests involving the debugger agent multiple times without failure.

This makes it possible to remote debuggers to just add commands to the queue without having to request a break as well. As soon as any JavaScript executes the debugger commands will be processed and the response send to the remote debugger.
Currently hide this behind a flag (--debugger-auto-break) as the current command line debugger in Chrome is not designed for this new behaviour, whereas the new Chrome developer tools will use it.

of an empty handle in case of an exception. This problem can break
C++ programs that are not interested in catching exceptions and just
want to propagate them out by testing for empty handles.
The issue is that exceptions are not rescheduled if they are
externally caught. Externally caught exceptions have to be
rescheduled if there is a JavaScript frame on the way to the C++ frame
that holds the external handler.

Changed the script break points to be able to handle both break points based on script names and script ids. When break points are set through a script id the position is relative to the script itself. This is different from the script break points set through script names where the line/coulmn offset is taken into account.
This has the side effect that function break points are not converted into script break points for named scripts.

This is mainly to avoid these scripts showing up in the debugger when showing normal scripts.
Removed the check for the empty script in the debugger function returning loaded scripts as this check only filtered out the empty script from the debugger context and not empty scripts in all other contexts. Also this filter did not take the script for the empty function into account.

JavaScriptFrameIterator is templatized on the iterator type and renamed to JavaScriptFrameIteratorTemp.
The original JSFI is now a typedef for JavaScriptFrameIteratorTemp<StackFrameIterator>. Because of templatizing, JSFI code is moved to frames-inl.h
StackTraceFrameIterator moved to frames.*
Implemented SafeStackFrameIterator which wraps StackFrameIterator and have the same interface. It performs additional checks of stack addresses prior to delegating to StackFrameIterator. SafeSFI is used in an another specialization of JavaScriptFrameIteratorTemp template to perform safe JS frames iteration on sampler ticks.

On Mac OS only the option SO_REUSEADDR is set to true for server sockets. Running the test required it as the bound listener socket would sometimes end up in TIME_WAIT. On Windows and Linux this has never been observed (given the client end of the socket is closed before the server end).

Add the ability to have the host embedding V8 receive a callback in the V8 thread while V8 is processing a debug callback. When V8 is processing a debug callback the thread where V8 is executing is sitting in a tight loop processing debug commands until the continue command has been executed. In some embedding situations it is beneficial to be able to call back into the embedding host from the thread where V8 is sitting. The might have functions which needs to be called to complement the JavaScript debugging.
