b3cee0a981 * aoutx.h (NAME(aout,canonicalize_reloc)): Don't error out if

4002f18a05 Made sure that every call to bfd_read, bfd_write, and bfd_seek
checks the return value and handled bfd_error correctly.  These
	changes are not itemised.

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_get_symtab_upper_bound, and changed it and
	_bfd_canonicalize_symtab and _get_reloc_upper_bound and
	_bfd_canonicalize_reloc to all return long.

34dd8ba311 Eliminate "int8_type", "int16_type", "int32_type", and their
variants from the BFD universe.  Leave the 64-bit types for now,
since they are in flux.

* aoutx.h, hp300hpux.c:  Eliminate needless (int32_type) casts.
* libaout.h (GET_SWORD):  Convert (int32_type) to (int).
* ieee.c:  Convert uint8e_type => unsigned char.
* oasys.c:  Extensive changes to eliminate obsolete types.
These depend on changes in ../include/oasys.h as well.
