pf: make contents of struct pfsync_state configurable

Make struct pfsync_state contents configurable by sending out new
versions of the structure in separate subheader actions. Both old and
new version of struct pfsync_state can be understood, so replication of
states from a system running an older kernel is possible. The version
being sent out is configured using ifconfig pfsync0 … version XXXX. The
version is an user-friendly string - 1301 stands for FreeBSD 13.1 (I
have checked synchronization against a host running 13.1), 1400 stands
for 14.0.

A host running an older kernel will just ignore the messages and count
them as "packets discarded for bad action".

pfsync: Remove deletion of states using the full pfsync_state struct

State deletions are sent over pfsync using struct pfsync_del_c.

Remove the code for receiving state deletions using struct pfsync_state
as such deletions are never sent. Rename functions and constants so that
only the "compressed" versions remain.

pfsync: prepare code to accommodate AF_INET6 family

Work is ongoing to add support for pfsync over IPv6. This required some
changes to allow for differentiating between the two families in a more
generic way.

This patch converts the relevant ioctls to using nvlists, making future
extensions (such as supporting IPv6 addresses) easier.

sys: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

Remove more constants related to static sysctl nodes. The MAXID constants
were primarily used to size the sysctl name list macros that were removed
in r254295. A few other constants either did not have an associated
sysctl node, or the associated node used OID_AUTO instead.
