When invoked by inetd, ctlstat -P will now produce output suitable for
ingestion into Prometheus.

It's a drop-in replacement for https://github.com/Gandi/ctld_exporter,
except that it doesn't report the number of initiators per target, and
it does report time and dma_time.

Rewrite CTL statistics in more simple and scalable way.

Instead of collecting statistics for each combination of ports and logical
units, that consumed ~45KB per LU with present number of ports, collect
separate statistics for every port and every logical unit separately, that
consume only 176 bytes per each single LU/port. This reduces struct
ctl_lun size down to just 6KB.

Also new IOCTL API/ABI does not hardcode number of LUs/ports, and should
allow handling of very large quantities.

Bunch of improvements to ctlstat.

Add -p option to allow filtering by ports.
Make -l and -p options work in all modes as filters.
Improve output formatting to better fit columns.

Catch up with HEAD (r280229-r284686).
