* symfile.h (struct section_addr_info ): Remove fields for special
treatment of .text, .data and .bss sections.
* solib.c (symbol_add_stub): The special field text_addr is not
available anymore. Search for the .text field the hard way.
* symfile.c (build_section_addr_info_from_section_table): Don't
fill in {text, data, bss}_addr any more.
(default_symfile_offsets): Don't use {text, data, bss}_addr fields
to fill in section_offsets for objfile.
(syms_from_objfile): Don't deal with {text, data, bss}_addr as a
special case anymore.
(add_symbol_file_command): Ditto.
