netconsole: validate a target's IP address configuration

This series adds two validations to the target configuration when the
user tries to enable it: first whether remote_ip was set, and second
whether local_ip and remote_ip address families match. Refuse to enable
the target if any of those validations fail.

These validations are already done for the target passed on the
command-line, so this aligns dynamic targets with the command-line
behavior.

The first two patches replace the per-target 'ipv6' flag with a
per-address 'family' field, which makes it easier to detect these error
conditions. Patches 3 and 4 implement the actual validations.

Patches 5-7 are follow-ups from previous reviews: move inet_addr from
netpoll.h into netconsole.c, show an unset address as an empty string
rather than "0.0.0.0", document local_ip auto-selection.
