Fix bug#23293 "readline detection broken on NetBSD":

Browse source 
Its root cause is a difference between the "readline" and "libedit" (header files)
definitions of "rl_completion_entry_function", where the "libedit" one is wrong anyway:
This variable is used as a pointer to a function returning "char *",
but "libedit" declares it as returning "int" and then adds casts on usage.

Change it to "CPFunction *" and get rid of the casts.
