Subject:         * symtab.c (multiple_symbols_ask, multiple_symbols_all)      
   (multiple_symbols_cancel): New constants.         (multiple_symbols_modes,
 multiple_symbols_mode): New static globals.        
 (multiple_symbols_select_mode): New function.         (_initialize_symtab):
 Add new set/show multiple-symbols commands.         * symtab.h
 (multiple_symbols_ask, multiple_symbols_all)        
 (multiple_symbols_cancel, multiple_symbols_select_mode): Declare.         *
 ada-lang.c (user_select_syms): Add handling of new multiple-symbols        
 setting.         * linespec.c (decode_line_2): Likewise.
