* Merge in HPPA/BSD patches from Utah:

	* defs.h:  Add const to 2nd arg of psignal prototype.
	* hppah-tdep.c:  Renamed to hppa-tdep.c 'cuz it's common code with
	BSD now.
	* hppab-core.c:  Deleted.  No longer useful.
	* hppab-nat.c:  #include more files.  Use PT_WUREGS, not
	PT_WRITE_U.
	* hppab-tdep.c:  Deleted.  Supplanted by hppa-tdep.c.
	* config/pa/hppabsd.mh (NATDEPFILES):  Remove hppab-core.o.
	* config/pa/hppabsd.mt (TDEPFILES):  hppab-tdep.o => hppa-tdep.o
	* config/pa/hppahpux.mt (TDEPFILES):  hppab-tdep.o => hppa-tdep.o
	* config/pa/xm-hppab.h:  #define SET_STACK_LIMIT_HUGE.
