* Support debugging using native MACH primitives on hppa*-*-osf*.

	* configure.in: hppa*-*-osf* != hppa*-*-bsd* anymore.
	* config/pa/hppaosf.mh: New file.
	* config/pa/nm-hppao.h: Likewise.
	* hppam3-nat.c: Likewise.
	* config/pa/tm-hppao.h (PSW_SS): Define for single-stepping.
	(MACHINE_CPROC_*_OFFSET): Define.
	(TRACE_*): Define.
	(START_INFERIOR_TRAPS_EXPECTED): Delete definition.
