Lots of changes from gas-bfd work. Includes:
* working reloc lookup support * better support for creation of COFF files from scratch * misc doc changes, macro tweaks, "const" additions, typo fixes, etc. * one or two ugly kludges that should get cleaned up (but what's one or two more, in BFD?) See ChangeLog for details.
