- Warn, don't exit, when SIOCSLAGGPORT returns an error.
When we exit with an error during lagg creation, a single
failed NIC (which no longer attaches) can prevent lagg
creation and other configuration, such as adding an IPv4
address, and thus leave a machine unreachable.
- Preserve non-EEXISTS errors for exit status from SIOCSLAGGPORT,
in case scripts are looking for it. Hopefully this can be
extended if other parts of ifconfig can allow a "soft" failure.
- Improve the warning message to mention what lagg and what

Introduce show_state structure to keep information about printed opcodes.
Split show_static_rule() function into several smaller functions. Make
parsing and printing opcodes into several passes. Each printed opcode
is marked in show_state structure and will be skipped in next passes.
Now show_static_rule() function is simple, it just prints each part
of rule separately: action, modifiers, proto, src and dst addresses,
options. The main goal of this change is avoiding occurrence of wrong
result of `ifpw show` command, that can not be parsed by ipfw(8).
Also now it is possible to make some simple static optimizations
by reordering of opcodes in the rule.

According to 802.1Q-2014, VLAN tagged packets with VLAN id 0 should be
considered as untagged, and only PCP and DEI values from the VLAN tag
are meaningful. See for instance
https://www.cisco.com/c/en/us/td/docs/switches/connectedgrid/cg-switch-sw-master/software/configuration/guide/vlan0/b_vlan_0.html.
Make it possible to specify PCP value for outgoing packets on an
ethernet interface. When PCP is supplied, the tag is appended, VLAN
id set to 0, and PCP is filled by the supplied value. The code to do
VLAN tag encapsulation is refactored from the if_vlan.c and moved into
if_ethersubr.c.
Drivers might have issues with filtering VID 0 packets on
receive. This bug should be fixed for each driver.

If the operation is not an update, if neither r/w nor r/o mode is
explicitly requested, if the error code hints at the possibility of the
media being read-only, and if the fallback is allowed, then we can try
to automatically downgrade to the readonly mode.
This is especially useful for auto-mounting of removable media that
sometimes can happen to be write-protected.
The fallback to r/o is not enabled by default. It can be requested on a
per-mount basis with a new mount option, 'autoro'. Or it can be
globally allowed by setting vfs.default_autoro.

Most sysctl nodes only return a single value, but some nodes return an
array of values (e.g. kern.cp_time). sysctl(8) understand how to display
the values of a node that returns multiple values (it prints out each
numeric value separated by spaces). However, until now sysctl(8) has
only been able to set sysctl nodes to a single value. This change
allows sysctl to accept a new value for a numeric sysctl node that contains
multiple values separated by either spaces or commas. sysctl(8) parses
this list into an array of values and passes the array as the "new" value
to sysctl(2).

The lookup_host() helper subroutine emits a struct in_addr value in network
byte order via caller passed pointer. However, the table value is expected
to be stored in host byte order. On little-endian machines, this produced a
reversed endian table value for Legacy or IPv4 table types when the value
was a hostname (instead of a plain IP address).
Fix by using ntohl() on the output 32-bit address.
While here, avoid some aliasing violations by storing the lookup_host()
output in an intermediate object of the correct type.

When dhclient first starts, if an old IP address exists in the
dhclient.leases file, dhclient(8) sends early DHCPREQUEST message(s)
in an attempt to re-obtain the old IP address again. These messages
contain the old IP as a requested-IP-address option in the message
body (correct) but also use the old IP address as the packet's source
IP (incorrect).
RFC2131 sec 4.1 states:
DHCP messages broadcast by a client prior to that client obtaining
its IP address must have the source address field in the IP header
set to 0.
The use of the old IP as the packet's source address is incorrect if
(a) the computer is now on a different network or (b) it is on the
same network, but the old IP has been reallocated to another host.
Fix dhclient to use 0.0.0.0 as the source IP in this circumstance
without removing any existing functionality. Any previously-used old
IP is still requested in the body of an early DHCPREQUEST message.
