Some more cleanups of symfile.c, using bfd access methods instead of
accessing private bfd data fields.  In several cases (those that 
would require touching more than one source file) I've just added
a FIXME comment and deferred doing the actual work.

2002-01-11  Michael Snyder  <msnyder@redhat.com>

	* symfile.c (build_section_addr_info_from_section_tab):
	Use bfd access method instead of manipulating bfd directly.
	(syms_from_objfile): Ditto.
	(simple_overlay_update_1): Ditto.
	(simple_overlay_update): Ditto.
	(generic_load): Ditto.
	(overlay_unmapped_address): FIXME comment, bfd access methods.
	(sections_overlap): FIXME comment, bfd access methods.
	(pc_in_mapped_range): FIXME comment, bfd access methods.
	(pc_in_unmapped_range): FIXME comment, bfd access methods.
	(section_is_mapped): FIXME comment, bfd access methods.
	(section_is_overlay): FIXME comment, bfd access methods.

Michael, there are some typos in your patch. I get the following errors:

Maybe you wanted asection instead of osection?

Modulus that, the patch is ok.
