The alfred server always needs interfaces to operate on. But these
interfaces might not exist at the moment when the daemon process is
started. This situation stopped the startup process after the init scripts
waited for a longer period of polling the system state.

But alfred is able to deal with interfaces which disappeared at runtime but
existed at startup. To force a similar behavior for the alfred startup, the
parameter "--force" or "-f" is used. The extra polling code is therefore no
longer needed in the init scripts.

Alfred can be stopped during a (re)start or reload when:

* disabled = 1
* batman-adv interface is missing
* MAC based EUI64 IPv6 link-local address not set

It is assumed that procd detects that the procd instance definition
disappeared and the currently running instance must be stopped. But all
these checks were triggering an "exit" which then stopped the alfred init
script and the wrapper from /lib/functions/procd.sh. And thus procd was
never informed about the instances which should be changed.

The correct handling is to return the result of the function instead of
directly killing the init scripts.

The OpenWrt routing feed was tried to be merged together with the OpenWrt
package feed. But they ended up being rejected due to formalities like the
slightly different package template. Just moving to the OpenWrt package
based one should simplify similar approaches in the future.

This changes the package version string so it does not start
with "openwrt", but with the base version we are modifying:

So far: openwrt-2019.4-1
Now:    2019.4-openwrt-1

Since it's us modifying version 2019.4 (in this case), this order
is more convenient (and also closer to what the kernel version
string does).

The batman-adv kernel module can be build without sysfs support. This will
stop the kernel module from creating the "mesh" directory. The alfred init
script must not depend on this folder to start the daemon up.

The alfred daemon allows to be started with multiple interfaces. The first
interface is used for communication and to calculate the source mac
address. The rest of the interfaces are only used for communication.

OpenWrt is using a modified version of the software and these modifications
may introduce extra bugs (or behavior changes). It is also patched for
stable releases instead of switching to new releases. The revision should
therefore be added to the version number to make it easier understandable
which modified version the user may have installed.

Occationally /proc/net/if_inet6 contains interface IDs with
three digits. In this case, the regex in wait_for_ll_address()
does not work anymore and alfred is not starting.

This patch changes the evaluation so that fields are used instead
of the mere position by counting characters.
