(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.
(target_notice_signals): new macro to cover new field.
* target.c (cleanup_target): default to_notice_signals to ignore.
