RFC: JDWP ExceptionEvent Notification

[Kyle Galloway]

This patch implements JDWP notification for Exception Events that occurr 
in interpreted code.  I uses a a manager class ExceptionManager to 
record exceptions and whether or not they are caught.  As the exception 
moves up the call stack, if it is caught the manager is notified and 
generates an appropriate JDWP event.  If the exception is never caught, 
the manager is notified and again send an appropriate JDWP event.  This 
code is ifdefed in so that the code is only executed inside 
_Jv_InterpMethod::run_debug and not when debugging is disabled.  
Comments, or can I commit this?

Thanks,

Kyle
