Mips bringup and general cleanup

Browse Source 
* cplus-dem.c:  Move CPLUS_MARKER define to after defs.h.
        * infptrace.c (PT_WRITE_D, PT_READ_D):  Use correct values.
        (This still doesn't seem to make MIPS bkpts work.)
        * mipsread.c:  Remove dup "Reading symbol data..." msg.
        (symbol_file_command, add_file_command):  Remove, obsol.
        * printcmd.c (ptype_command):  Say "an enum" rather than "a enum".
        Wrap output appropriately.
        * stack.c (locals_info, catch_info, args_info):  Check
        selected_frame rather than target_has_stack or coredumping.
        * valprint.c (type_print_varspec_suffix):  Wrap "ptype" output of
        enums appropriately.
