Remove 12.x ABI compat for kernel dump ioctls
This code was marked gone_in(14), so it can now be removed.
The only consumer of this interface is dumpon(8). We do not maintain
strict backwards compatibility for this utility because a) it
can't/shouldn't be used from a jail or chroot and b) it is highly
specific interface unique to FreeBSD. The host's (presumably more
up-to-date) copy of dumpon(8) should be used to configure kernel dump
devices.

Add ddb(4) 'netdump' command to netdump a core without preconfiguration
Add a 'X -s <server> -c <client> [-g <gateway>] -i <interface>' subroutine
to the generic debugnet code. The imagined use is both netdump, shown here,
and NetGDB (vaporware). It uses the ddb(4) lexer, with some new extensions,
to parse out IPv4 addresses.
'Netdump' uses the generic debugnet routine to load a configuration and
start a dump, without any netdump configuration prior to panic.
