Hooks and interface scripts are now sourced more systematically.
Settings of wireless profiles that depend on hooks are now picked up
correctly by netctl-auto.

The same functionality is provided by wpa_supplicant, so we do not need
an extra and Arch Linux specific dependency.

Inside double quotes, backslash is an escape character. Hence, it is
cleaner to use single quotes where backslashes may occur. This includes
pattern strings for print, grep, and sed.

Reported by Michaël Cadilhac <michael@cadilhac.name>

A generated config file could be left behind.
This occurs for instance when a removable interface is removed when used
or when an interface is blocked by rfkill, but netctl is not instructed
to utilize its rfkill routines.

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.

netctl-auto/wpa_actiond will hang on startup, if wpa_supplicant creates
an additional control interface and with the -W switch waits for a
connection on all control interfaces on startup.

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

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

Instead of using systemctl to manage the netctl-auto service, some users try to
invoke the start/stop commands of netctl-auto directly. Although this behaviour
is explicitly discouraged in the man page, this seems to be a source of
confusion.

The changes introduced in de8c80f6 will cause other netctl-auto commands to fail
if the netctl-auto service was not spawned by systemd. Therefore, this change
emits an error message if netctl-auto [start|stop] is invoked from an
interactive terminal.

Instead of searching for wpa_actiond pid files, the netctl-auto
utility now looks for running systemd netctl-auto units.

Testing whether transmission is blocked at all is now possible through

    [[ -n $(rf_status "$Interface" "$RFKill") ]]

This adds a command line interface to the netctl-auto script to
allow users more control over the automatic profile selection.

Use 'wpa' to refer to the 802.11i and 802.1x client side software
(wpa_supplicant) in general.

wpa_supplicant would not immediately terminate with an attached ctrl monitor.

This settles a style for 'case' statements:
The label and closing colons are indented with two spaces,
The body is indented with two more, totalling four spaces.

Curtis Shimamoto noted it did not work.

This commit contains the refactoring and rewriting of code.

This commit contains the moving of files.

Prepare for the 3.0 release.

The command argument to timeout_wait cannot reference positional parameters (they would become the positional parameters to timeout_wait).
We kill wpa_actiond if it does not die with wpa_supplicant.

wpa_actiond kills itself when wpa_supplicant propagates its termination.

This may be set in a custom supplicant configuration file. All this is needed to cater for that.
The new name of the tracking variable is WPA_CTRL_DIR, conform the environment variable of wpa_cli -a.

The previous commit alters the config file (/etc/conf.d/netcfg), marking the right moment for this change.

Configuration is done through /etc/conf.d/netcfg.
Compatibility with configuration through /etc/rc.conf is dropped.

It needs to be quoted when used as an argument. Putting the name in curly braces is unnecessary.

-i is not a very cool parameter for downing an interface. Change it to -D so that it mirrors -R in the sense that a capital is used for interface-based actions.
The old behaviour is kept (undocumented) for backward compatibility.

Also a typo (iface-recont should have been iface-recon) is fixed.

Lastly some restrictions on profile naming are included in the documentation. The "should not start with '@'" is only for usage with net-profiles.

The use of cat in a subshell is distractive.
This makes the code more beautiful.

This is what you get when Dave Reisner points you at some bash anti-patterns.
Also in this commit:
- updated documentation
- bugfix revision of the IPv6 SLAAC address/route bug

It is now possible to reconnect based on the name of the interface.
