Only two interfaces are created eth0 and lo and they expose
the following properties:
address, addr_len, flags, ifindex, mty, tx_queue_len and type.

Initial patch developed by Carlos Neira in 2017 and finished by me.

There's no need to pre-malloc the number of handles. Instead call
LocateHandles twice, once to get the size, and once to get the
data.

This allows us to remove three nearly identical functions because the
differences don't matter, and the size difference is trivial.

Allow users to specify multiple dump configurations in a prioritized list.
This enables fallback to secondary device(s) if primary dump fails.  E.g.,
one might configure a preference for netdump, but fallback to disk dump as a
second choice if netdump is unavailable.

This change does not list-ify netdump configuration, which is tracked
separately from ordinary disk dumps internally; only one netdump
configuration can be made at a time, for now.  It also does not implement
IPv6 netdump.

savecore(8) is already capable of scanning and iterating multiple devices
from /etc/fstab or passed on the command line.

This change doesn't update the rc or loader variables 'dumpdev' in any way;
it can still be set to configure a single dump device, and rc.d/savecore
still uses it as a single device.  Only dumpon(8) is updated to be able to
configure the more complicated configurations for now.

As part of revving the ABI, unify netdump and disk dump configuration ioctl
/ structure, and leave room for ipv6 netdump as a future possibility.
Backwards-compatibility ioctls are added to smooth ABI transition,
especially for developers who may not keep kernel and userspace perfectly
synced.

Don't allow unprivileged users to set SGID on files to whose group they
don't belong.  This is slightly different than what POSIX says we should do
(clear sgid on return from a successful chmod), but it matches what UFS
currently does.

As Linux comment for this function point:
Signal to the system that the PCI device is not in use by the system
anymore. This only involves disabling PCI bus-mastering, if active.
