    Better fix for PR 20499, including preventing strlen from being called on
an uninitialised name field.

        PR gprof/20499
        * corefile.c (BUFSIZE): Define.
        (STR_BUFSIZE): Define.
        (read_function_mappings): Use BUFSIZE and STR)BUFSIZE.
        (num_of_syms_in): Move buf, address and name arrays out of
        function and declare as static BUFSIZE arrays.
        Use STR_BUFSIZE when scanning for name and address.
        (core_create_syms_from): Revert previous delta.  Instead
        short circuit the parsing of a symbol if all three fields
        could not be found.
