nutscan_scan_avahi - Scan network for NUT services via mDNS

The nutscan_scan_avahi() function tries to detect the NUT service via mDNS, and its associated devices. It uses the Avahi library to do so. You MUST call nutscan_init(3) before using this function. This function can query perspective IP addresses using NUT protocol, and in this case it waits up to usec_timeout microseconds before considering an IP address to be unresponsive.
