* mach-o.h (BFD_MACH_O_SEGNAME_SIZE): New macro. (BFD_MACH_O_SECTNAME_SIZE): Ditto. (bfd_mach_o_section): Use them. Add next field. (bfd_mach_o_segment_command): Replace sections array by sect_head and sect_tail. (bfd_mach_o_get_mach_o_section): New macro. (bfd_mach_o_lookup_section): Remove. (bfd_mach_o_new_section_hook): New function. * mach-o.c (bfd_mach_o_normalize_section_name): Use strncmp instead of strcmp. (bfd_mach_o_convert_section_name_to_bfd): Replaces section parameter with segname and sectname parameters. Adjust. (bfd_mach_o_append_section_to_segment): New function. Use a linked list for Mach-O sections. (bfd_mach_o_write_segment_32): Adjust. (bfd_mach_o_write_segment_64): Ditto. (bfd_mach_o_build_commands): Fix comment. Adjust. (bfd_mach_o_flatten_sections): Adjust. (bfd_mach_o_print_section_map): Adjust. (bfd_mach_o_set_section_flags_from_bfd): Ditto. (bfd_mach_o_new_section_hook): New function. (bfd_mach_o_init_section_from_mach_o): Ditto. (bfd_mach_o_read_section_32): Remove section parameter. Return a section instead. (bfd_mach_o_read_section_64): Ditto. (bfd_mach_o_read_section): Ditto. (bfd_mach_o_make_bfd_section): Adjust. (bfd_mach_o_read_segment): Adjust for new profile of bfd_mach_o_read_section. (bfd_mach_o_lookup_section): Remove. * mach-o-target.c (bfd_mach_o_new_section_hook): Remove.
