Changes to let BFD return an error indication from
	get_symtab_upper_bound, bfd_canonicalize_symtab,
	bfd_get_reloc_upper_bound, and bfd_canonicalize_reloc.  They now
	return long instead of unsigned int, and use -1 to indicate an
	error.  Along the way, rename get_symtab_upper_bound to
	bfd_get_symtab_upper_bound.

	* targets.c (bfd_target): Renamed _get_symtab_upper_bound to

	_bfd_canonicalize_symtab and _get_reloc_upper_bound and
	_bfd_canonicalize_reloc to all return long.

9783e04a64 Make all callers of malloc or realloc (including via obstacks)
