[issue20525] Got compiler warning when compiling readline module

[Vajrasky Kok]

New submission from Vajrasky Kok:

On Fedora 20, I got this compiler warning:

/home/sky/Code/python/cpython3.4/Modules/readline.c: In function ‘flex_complete’:
/home/sky/Code/python/cpython3.4/Modules/readline.c:962:5: warning: passing argument 1 of ‘completion_matches’ discards ‘const’ qualifier from pointer target type [enabled by default]
     result = completion_matches(text, *on_completion);
     ^
/home/sky/Code/python/cpython3.4/Modules/readline.c:40:15: note: expected ‘char *’ but argument is of type ‘const char *’
 extern char **completion_matches(char *, rl_compentry_func_t *);
               ^

Here is the patch using Christian Heimes' strategy in silencing compiler warning in dbm module.
