* hppa.c (hppa_object_setup): Get rid of all knowledge of stabs 

debug info.  Setup info about linker symbols only, and use
	standard bfd fields to hold the info.
	* (hppa_object_p):  Remove unneeded decls.
	* (hppa_new_section_hook):  Get rid of most of this.
	* libhppa.h (struct hppadata):  Remove ten pounds of useless ugly
	fat.  Remove all knowledge of stabs, remove redundant knowledge of
	linker symbols.
	* Remove macros for accessing fields which are now gone.
