[Unbound-core] proposed diff to cli_loop()

[Jose N. <jo...@mo...>]

the attached diff changes the api in cli_loop to accepting two file
descriptors now, fd in (to read from) and fd out (to pass the prompt to).
tested on openbsd-current using test1.

the goal is to allow for the silent operation of a cli_loop() paarsing a
file, for example, by setting fd out to -1 (it just sets streamout to
/dev/null, w+).

feedback welcome.
