Make the readline.c functionality reusable. Instead of calling monitor_printf() and monitor_flush() directly, invoke function pointers provided by the user. This way readline.c does not know about Monitor and other users will be able to make use of readline.c. Note that there is already an "opaque" argument to the ReadLineFunc callback. Consistently call it "readline_opaque" from now on to distinguish from the ReadLinePrintfFunc/ReadLineFlushFunc "opaque" argument. I also dropped the printf macro trickery since it's now highly unlikely that anyone modifying readline.c would call printf(3) directly. We no longer need this protection.
