avahi_simple_poll_iterate isn't using the provided timeout

[michaelrsweet]

When I call avahi_simple_poll_iterate with a timeout of 2500 milliseconds, it calls poll() with a timeout of 0. Similarly, if I set a poll function it gets 0 for the timeout.

Avahi 0.6.30-3.fc15.x86_64 on Fedora 15 (yeah, I know that's "old"...)
