The name of the subcommand mirrors the same subcommand of systemd-analyze.

Verification before restarting would be useful. However, verification
requires the profile file to be readable by the current user. The current
user may be a regular user with permission to control systemd, so
restarting does not require the profile file to be readable. Therefore, we
do not attempt verification before restarting.

Connection types bond, bridge, dummy, vlan, and macvlan create their own
interface. Previously, only macvlan offered control over the MAC address of
the created interface. Now, this functionality is available to all these
connection types.

Distinguish between started profiles and online profiles in the output
of the list subcommand of netctl.
To be consistent in symbol usage, the wifi-menu flags have changed too.

The netctl@ service now yields before obtaining an IP address. This
prevents holding up network.target unnecessarily. Waiting for profiles
to obtain an IP address is possible through

1) The netctl-wait-online service
This service waits until all enabled profiles have obtained an address.
It is ordered before network-online.target so that this target is now
correctly implemented in netctl.

2) The wait-online <PROFILE> subcommand to netctl
This command waits for a started profile to obtain an address.

This adds the LinkOptions= variable for use with connection types that
add interfaces (bond, bridge, dummy, macvlan, vlan). This variable is
not portable in the event of moving away from iproute2, so common
options should still get their own variables.

Status getting commands are now uniform between netctl and netctl-auto.
Both support 'is-active' and 'is-enabled'. The 'current' command is
dropped from netctl-auto. Its use case is covered by the 'list' command.

The ppp chat messages in mobile_ppp connections need to be customized
for some services/devices.

Only relevant for GRE tunneling.

The previous wired automatic profile selection procedure was not
properly documented.

Now both wired and wireless automatic profile selection use
ExcludeAuto= and Priority=

Somehow, these have gone unnoticed for quite some time.

This option sets a frequency to use in ad-hoc mode for a newly created IBSS
(when it is going to be created).

Ifenslave is deprecated according to the kernel documentation:
https://www.kernel.org/doc/Documentation/networking/bonding.txt
It also added an additional, unnecessary dependency. I tried to update
the documentation to reflect this change.

This should at some point take care of most PPP use cases, but
currently is just a frontend to pppoe. The main difference is that the
new connection type keeps track of profiles by their 'dynamic' interface
name. Hence it is not wise to use both pppoe and ppp profiles.
