Add configure option to disable readline.

Apparently the Gnulib readline module does not provide any obvious way
for users to disable it.  Setting the gl_cv_lib_readline cache variable
works but probably only Autoconfers will know how to discover that.

Add an explicit --with-readline (and --without-readline) option which
internally sets this.  Since this option shows up in configure's help
output it is hopefully more obvious.
