* target.h: Add enum target_waitkind, enum target_signal, and

	struct target_waitstatus.  Change status argument to target_wait to
	be struct target_waitstatus * instead of int *.
	* target.h, infrun.c, all targets: Change type of signal arguments
	to resume(), proceed(), and target_resume() from int to enum
	target_signal.
	* All targets (*_wait, *_resume): Change accordingly.
	* infcmd.c (program_info, signal_command), throughout infrun.c,
	* fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
	* convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
	signal code stuff right with the new signals would be non-trivial).
	* inferior.h (stop_signal): Make it enum target_signal not int.
	* target.c, target.h (target_signal_to_string, target_signal_to_name,
	target_signal_from_name): New functions.
	* inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
	store_waitstatus): New functions.
	* procfs.c (procfs_notice_signals): Use them.
	* i960-tdep.c (i960_fault_to_signal): New function, to replace
	print_fault.
	* config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
