stop_signal.

	* inferior.h (stop_signal): Delete.
	* gdbthread.h (save_infrun_state, load_infrun_state): Remove
	stop_signal argument.
	* thread.c (load_infrun_state, save_infrun_state): Remove
	stop_signal argument.  Don't reference it.

	* infcmd.c (stop_signal): Delete.
	(program_info): Adjust.
	* infrun.c (resume): Clear stop_signal.
	(proceed): Adjust.  Pass the last stop_signal to the thread we're
	resuming.
	(context_switch): Don't context-switch stop_signal.
	(handle_inferior_event, keep_going): Adjust.
	(save_inferior_status, restore_inferior_status): Adjust.

	* fbsd-nat.c: Include "gdbthread.h".
	(find_signalled_thread, find_stop_signal): New.
	(fbsd_make_corefile_notes): Use it.
	* fork-child.c (startup_inferior): Adjust.

	(linux_nat_do_thread_registers): Adjust.
	(find_signalled_thread, find_stop_signal): New.
	(linux_nat_do_thread_registers): Add stop_signal parameter.
	(struct linux_nat_corefile_thread_data): Add stop_signal member.
	(linux_nat_corefile_thread_callback): Pass stop_signal.
	(linux_nat_do_registers): Delete.
	(linux_nat_make_corefile_notes): Use find_stop_signal.  Assume
	there's always a thread.

	* procfs.c (find_signalled_thread, find_stop_signal): New.
	(find_stop_signal): New.
	(procfs_do_thread_registers): Add stop_signal parameter.
	(struct procfs_corefile_thread_data): Add stop_signal member.

	(procfs_make_note_section): Find the last stop_signal.

	* solib-irix.c: Include gdbthread.h.
	(irix_solib_create_inferior_hook): Adjust.
	* solib-osf.c: Include gdbthread.h.
	(osf_solib_create_inferior_hook): Adjust.
