75f3ef7a63 * ecoff.c, libecoff.h, ecoffswap.h, coff-alpha.c, coff-mips.c, 
elf32-mips.c: Renamed all externally visible ECOFF routines which
	are local to BFD to start with _bfd_ecoff instead of just ecoff.

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

	the debugging information if it has already been read.
	(ecoff_indirect_link_order): Handle _cooked_size being different
	from _raw_size.  Don't reread the contents or the relocs if they
	have already been read in.

	18 to 16.
	(PCREL16_EXPANSION_ADJUSTMENT): Define.

	used_by_bfd field.  Call mips_relax_pcrel16 to handle details of
	expanding an out of range PCREL16.  Keep trace of adjustments
	required by expansions.  Set s and unset h when converting a reloc
	from undefined to section.  Change handling of PC relative relocs:
	if against a section, they are correct in the object file, if
	against an external symbol they are pcrel_offset.
	(mips_relax_section): New function.
