	* 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.
