* coffread.c (coff_sym_fns): Add default_symfile_segments.
* dbxread.c (start_psymtab): Check HAVE_ELF. (aout_sym_fns): Likewise. * elfread.c (elf_symfile_segments): New. (elf_sym_fns): Add elf_symfile_segments. * mipsread.c (ecoff_sym_fns): Add default_symfile_segments. * remote.c (get_offsets): Use symfile_map_offsets_to_segments. Skip if there is no symfile_objfile. Handle TextSeg and DataSeg. * somread.c (som_sym_fns): Use default_symfile_segments. * symfile.c (find_sym_fns): Take a BFD and return the sym_fns. (init_objfile_sect_indices): Call symfile_find_segment_sections. (default_symfile_segments): New function. (syms_from_objfile): Update call to find_sym_fns. (symfile_get_segment_data, free_symfile_segment_data): New. (symfile_map_offsets_to_segments): New. (symfile_find_segment_sections): New. * symfile.h (struct symfile_segment_data): New. (struct sym_fns): Add sym_segments. (default_symfile_segments, symfile_get_segment_data) (free_symfile_segment_data): New prototypes. (symfile_map_offsets_to_segments): Likewise. * xcoffread.c (xcoff_sym_fns): Add default_symfile_segments. * Makefile.in (COMMON_OBS): Remove elfread.o. (elf_internal_h): New. (elfread.o): Update. * configure.ac: Add elfread.o to COMMON_OBS if bfd/elf.o was compiled. * config.in, configure: Regenerated. * NEWS: Mention qOffsets changes. * gdb.texinfo (General Query Packets): Document qOffsets changes. * Makefile.def: Add dependency from configure-gdb to all-bfd. * Makefile.in: Regenerated.
