Replace ppp(4) removed since FreeBSD 8.0-RELEASE with vlan(4).
While here, remove commented out reference to non-existing "egress"
interface group hiding since initial import of interface groups
from OpenBSD in 2006.
Provide sticky ARP flag for network interface which marks it as the
"sticky" one similarly to what we have for bridges. Once interface is
marked sticky, any address resolved using the ARP will be saved as a
static one in the ARP table. Such functionality may be used to prevent
ARP spoofing or to decrease latencies in Ethernet networks.
The drawbacks include potential limitations in usage of ARP-based
load-balancers and high-availability solutions such as carp(4).
The implemented option is disabled by default, therefore should not
impact the default behaviour of the networking stack.

"ifconfig -g groupname" prints a list of interface names,
which could be confusing, because it differs from
the behavior of "ifconfig -a -g groupname".
While here, add two examples showing the difference between
"ifconfig -a -g groupname" and "ifconfig -g groupname".

This reference has been present in the manual page since the initial
import of BSD 4.4 Lite sbin Sources. It's time for it to be removed.

- Remove extraneous examples
- Apply "-compact" to the list macros so that it is possible to fit the
definitions of the types and formats in one terminal screen.

This change is about moving the -f documentation into the right place in
the manual. Also, document the IFCONFIG_FORMAT variable in the
ENVIRONMENT section.

In order to clean up the layout of the manual page, let's keep
parameters in the end of the DESCRIPTION section. This patch does not
change any content, it's meant to only move the content around before
refactoring.

- There is no need to mention in the synopsis that -f can be a list of
comma-separated type:format pairs. Let's keep it simple instead.
- Mention that -f can be supplied multiple times.
- Add -f to other entries in the synopsis where it can be used.

As documented, the -C flag can only be used on its own. Any other
command modifiers and flags are ignored when -C is used. Reflect that in
synopsis.

We document capability codes (the CAPS field of "ifconfig wlan0 scan")
in both ifconfig(8) and the handbook. The list is more complete in the
manual page, while the descriptions of individual capabilities are more
detailed in the handbook.
In order to reduce content duplication and bit rot, let's move
handbook's details to the manual page and reference the manual page
whenever necessary.

When we exposed the PFSYNCF_OK flag to userspace in 5f5bf88949 we
unintentionally caused defer mode to always be enabled.
The ioctl check only looked for nonzero, not for the PFSYNCF_DEFER flag.
Fix this check and ensure ifconfig sets the flag.
