[RFA] JMTI Exception Events

[Kyle Galloway]

I've had one or another variation of this lying around for some time, 
but I have finalized it.  This patch adds notification of JVMTI 
Exception Events.  In the catch section of the debug interpreter, it 
grabs information about the exception, then creates a new ExceptionEvent 
object.  This object handles checking if the exception has already 
generated an event, as well as whether or not the exception will be 
caught.  It then calls it's native side to dispatch the method.

In order to clean up the code in the catch block of the interpreter, I 
added check_handler, which does exactly what was done before, but makes 
things alot cleaner and allows me to call check_handler to see if an 
exception will be caught further up the stack.

Before I commit this, I wanted to clear up which files I should commit. 
  Do I need to include more than sources.am and Makefile.am?  For 
example, should the changed Makefile.ins go in as well?

Questions/comments/concerns?

Thanks,
Kyle
