This is a small daemon that was originally part of autowifi. It will be
a depend or optdepend on the next netcfg's auto-wireless mode. This will
be a reliable wireless roaming mode.
The daemon is somewhat similar to wpa_cli -a $script, but adds logging
and avoids race conditions by adding a timeout on disconnection, an idea
stolen from ifplugd.
Is it okay to bring this to core? Dependencies are only glibc and
wpa_supplicant, makedepends just gcc. Package is in testing for review.
