The structure consists of all current context - arguments,
open sockets, current family and so on.
Pass this structure as a first argument to most of the af_ menthods.
This allows to propagate and update shared data without using
global variables.
The diff is pretty large, but de-facto mechanical. All changes
except the structure setup in ifconfig[_netlink].c are one-line
mechanical changes.

The setvlantag() and setvlanproto() functions are used in two scenarios:
when we create a new vlan interface and when we update an existing
interface.
These are distinguished by the getvlan() at the end of the functions. If
this fails we assume that is because the interface doesn't exist (so
we're creating a new one). We only update the 'params' struct, and
expect the settings to be applied when we vlan_create().
However, if we're updating an existing interface we do not retrieve the
current settings, and can end up invalidating settings.
Fix this by using the settings we retrieved while checking which
scenario we're in.
Note that we do not address this for setvlandev(), because if_vlan does
not allow the vlan parent device to be changed without disassociating it
first (with ifconfig vlanX -vlandev).

If multiple threads are invoking "ifconfig XXX create" a race may occur
which can lead to two different error messages for the same error.
a) ifconfig: SIOCIFCREATE2: File exists
b) ifconfig: interface XXX already exists
This patch ensures ifconfig prints the same error code
for the same case.

802.1ad interfaces are created with ifconfig using the "vlanproto" parameter.
Eg., the following creates a 802.1Q VLAN (id #42) over a 802.1ad S-VLAN
(id #5) over a physical Ethernet interface (em0).
ifconfig vlan5 create vlandev em0 vlan 5 vlanproto 802.1ad up
ifconfig vlan42 create vlandev vlan5 vlan 42 inet 10.5.42.1/24
VLAN_MTU, VLAN_HWCSUM and VLAN_TSO capabilities should be properly
supported. VLAN_HWTAGGING is only partially supported, as there is
currently no IFCAP_VLAN_* denoting the possibility to set the VLAN
EtherType to anything else than 0x8100 (802.1ad uses 0x88A8).

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.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
Initially, only tag files that use BSD 4-Clause "Original" license.

o change vlan cloning to use callback and pass all vlan parameters
on create using the new SIOCREATE2 ioctl
o update vlan set logic to match existing practice
as both have been read from the command line. Still use the callback,
but this time only to verify that both vlan and vlandev have been
found on the command line.
This should allow for control over the relative order of processing
parameters, which is needed to satisfy some caveats of the if_vlan
driver. E.g., MTU cannot be changed on a vlan interface until it's
attached to its parent.

special-purpose code to display status for an interface for
state that was not address-oriented. This status reporting
was merged in to the address-oriented status reporting but
did not work for link address reporting (as discovered with
fwip interfaces). Correct this mis-merge and eliminate the
bogus kludge that was used for link-level address reporting.
o add an af_other_status method for an address family for
reporting status of things like media, vlan, etc.
o call the af_other_status methods after reporting address
status for an interface
o special-case link address status; when reporting all
status for an interface invoke it specially prior to
reporting af_other_status methods (since it requires the
sockaddr_dl that is passed in to status separately from
the rtmsg address state)
o correct the calling convention for link address status;
don't cast types, construct the proper parameter
This fixes ifconfig on fwip interfaces.
o break per-address family support out into separate files
o modularize per-address family and functional operations using
a registration mechanism; this permits configuration according
to which files you include (but beware that order of the files
is important to insure backwards compatibility)
o many cleanups to eliminate incestuous behaviour, global variables,
and poor coding practices (still much more to fix)
The original motivation of this work was to support dynamic addition
of functionality based on the interface so we can eliminate the various
little control programs and so that vendors can distribute ifconfig
plugins that support their in-kernel code. That work is still to be
completed.
o Update 802.11 support for all the new net80211 functionality; some
of these operations (e.g. list *) may be better suited in a different
program
