the gluon-announced package installs a hotplug script
that uses announce.lua from the gluon-announce package.

So we need to include gluon-announce as dependency.

This should reduce memory consumption a little.

gluon-ebtables-filter-multicast: allow hop-by-hop options as ICMPv6 is sometimes prefixed by an HBH header

the ports were interchanged, see the following packet flow:

client:546 --> [ff02::1:2]:547
server:547 --> client:546

therefore we need to allow outgoing multicast packets with dst-port 547
and unicast packets from bat0 to clients with dst-port 546 and 547 in the other direction

gluon-authorized-keys: add keys from site.conf

This package will run as invariant script after each upgrade and copy
all keys from site.conf's authorized_keys entry to
/etc/dropbear/authorized_keys.

Existing keys will be preserved.

The site.conf entry 'authorized_keys' is required (if this package is
selected) and must contain a list of strings, each representing a line
of the resulting file.

gluon-neighbour-info: query direct neighbours

IGMP snooping causes serious trouble with IPv6 neighbour discovery.

mesh-vpn-fastd: enable from site.conf

This patch allows fastd's enabled flag's default value to be set from
site.conf.

As the (removed) comment said, this was a one-time-hack that was obsoleted long ago.

This is a simple client for gluon-announced.

gluon-cron: Fix endless loop parsing invalid lines

Using the line
```
* * * * echo "foobar"
```
(notice the missing fifth time field) in a crontab causes gluon-cron
to enter an endless loop while parsing it, thus it won't even execute
the other, valid crontabs.

This is caused by the loop in [line 138] where `begin - min`
substracts the unsigned `min` from the signed `begin`. If now `begin`
is invalid, `strict_atoi` returns -1 and the loop starts at
`(-1)-1=MAX_INT` and runs while `i <= MAX_INT` which is always true.

The real culprit lies in [line 134] where exactly this case
`begin < min` is checked - but because of the signedness, this check doesn't
work as expected either.

The easiest solution is to make `min` a signed integer instead of an unsigned
one, as we do not require it to be very large and only pass the constants 0 or
1 to it.

To avoid other similar problems, this patch makes the input variable `n` a
signed integer as well.
