* objfiles.h (ImportEntry, ExportEntry): Remove types.

	(struct objfile): Remove import_list, import_list_size,
	export_list, export_list_size members.
	(is_in_import_list): Remove prototype.
	* objfiles.c (is_in_import_list): Remove.
	* somread.c (init_import_symbols, init_export_symbols): Remove.
	(som_symfile_read): Do not call init_import_symbols.  Do not
	set objfile->export_list and objfile->export_list_size.
