(target_bfd_xfer_partial): Adjust to get at the section table from the new structure. (target_bfd_get_section_table): Ditto. (target_bfd_xclose): Ditto. Get the bfd pointer from the target_bfd_data structure, from the section table. (target_bfd_reopen): Store a struct target_bfd_data in the target_ops to_data field, instead of a target_section_table.
