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.
Fixes: 45db0e60d2 ("alfred: use procd")

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.

The commit 45db0e6 introduced curly brackets which are not correct
syntax and thus broke the script.

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.

kmod-ipv6 is obsolete.
The symbol IPV6 is a global config symbol, don't select it because it
will override the user decision of IPV6 as all other package in base do
it. A select (+) will also create a recursive dependency error.

This reverts commit bcaa87776f.
Caused circular dependencies; reverted for now. (kmod-ipv6 explicit
dependencies _should_ be eliminated though, but this is clearly not
the way.)
Changes between alfred 2015.0 and 2015.1 cause alfred to print an error
and exit when the interface to bind to is not completely set up (has no
non-tentative link-local address). As a workaround, wait for such an
address by reading /proc/net/if_inet6 before alfred is started.
In the long term, it would be nice to make alfred more robust against
missing interfaces (allowing alfred to start without the interface
existing, and keeping it working even when the interface is removed and
re-added while alfred is running).
