This adds an additional parameter to perl's dtrace probes with the stash name of the subroutine. This generally looks nicer than the filename but gives a similar level of context. As this is an additional parameter this will not have an impact on existing DTrace scripts. (Also due to the way DTrace works I believe it does not break binary compatibility and would be safe to backport to maint-5.12 if desired, but I'm not a DTrace expert.)
