NOTICE_SIGNAL_HANDLING_CHANGE macro added to the target vector as
to_notice_signals. * inferior.h (proc_signal_handling_change): prototype removed. * infrun.c (NOTICE_SIGNAL_HANDLING_CHANGE): default removed. (handle_command): now calls target_notice_signals. * procfs.c (proc_signal_handling_change): renamed to procfs_notice_signals. Now static. Add prototype. All callers changed. * target.h (struct target_ops): new field, to_notice_signals.
