RFE: Enhance `upsd` to `LISTEN host:port` with one colon-separated parameter token

[jimklimov]

For kicks, tried if it would just work - no, it does not; the whole single/first token is seen as an address, and the lack of second token causes an attempt to use the default port number:

:; rm -rf /tmp/nnnn ; mkdir -p /tmp/nnnn && touch /tmp/nnnn/{ups.conf,upsd.conf,upsd.users}
:; echo 'LISTEN :::3493' > /tmp/nnnn/upsd.conf
:; ALLOW_NO_DEVICE=yes NUT_STATEPATH=/tmp/nnnn NUT_CONFPATH=/tmp/nnnn ./server/upsd -DDDDDD ; echo $?
