(report_overlay_modification): Renamed from verify_overlay_modification.

(call_overlay_mod_hooks): New args AFTER, ARG1, ARG2, ARG3.
Args START, END deleted.  Pass each function AFTER, ARG1 and ARG2,
and ARG3 if ARG3 is not nil.
(verify_overlay_modification): New args AFTER, ARG1, ARG2, ARG3.
Pass them to call_overlay_mod_hooks.
