	* elf32-hppa.c: Second half of major cleanup.  More comments,
	PARAMize and staticize rest of functions.  Delete unused
	functions.  Delete unused/unnecessary arguments to some functions.
	Group static vars together.  Abort for bad errors until we have
	error code propogation working.  Work on spacing and indention.
	Add FIXMEs for unresolved problems.  Use enums rather than
	#defines for lots of things.  Merge two functions which build
	linker stubs into a single function (so they can easily share a
	ton of common code).
