The router id "router_id" is only evaluated based on the
router_netif table. If the corresponding entry in the router
table is missing, an error occurs.
To deal with that, we now use the "olddata" variable for ifs,
which is initialized based on the router table. If nothing is
found there, we trigger delete_router to get rid of fragments
in other tables.
The latter is necessary, as we identify routers by MAC addresses
and thus old entries will keep to be a problem if just a new
entry is added to router_netif.

This is much easier to maintain and prevents from having a
wrong average if e.g. w2mesh and w5mesh are present, but only
the better one is used.

This patch aims at showing the client-caused traffic. We use
bat0 for this, at this seems to be the easiest way which does not
require router-specific ifs etc.
This patch distinguishes between routers and gateways:
- For routers, we just use the bat0 data
- For gateways, we aggregate eth0.1, eth1.1, w2ap and w5ap
This requires changes to the MySQL database!

This introduced a boolean gateway field, which is set based on
the gateway connections sent via alfred.
If a device provides no gateways which it is connected to, it is
assumed to respresent a gateway.

This change the behavior concerning the displayed netif name in
the legend of the neighbor stats plot. Previously, the netif name
of the device was shown, now we show the netif name corresponding
to the neighbor. This is necessary, as we do not log netif names
for neighbors.

(quick run)

The data for each netif is only loaded when the respective row
is clicked.
Correspondingly, br-mesh is loaded initially.
So far, it is unclear how big the impact of the netif filter in
MySQL transactions is, as those have no key of their own.

Sometimes two queries want to insert the same entry into the
router stats table, although we check for that right before the
query is made. One can suppress this by using ON DUPLICATE KEY UPDATE
to ignore the second (redundant) entry.
This is no fix, but will work until this is examined more thoroughly.

Since the gaps between alfred calls have been fixed, we can
reduce the waiting time before a router gets offline.
We now only tolerate a single missing data point, but not two
like before.

With router_rate_limit_list, routers were not processed if the
time difference between calls was less than 5 minutes for the
same MAC address.
While this is generally not bad, there are some drawbacks:
- Not having been aware of this fact, we have established other
mechanisms to dilute data density, which might have interfered
- With KeyXchangeV2, two gateways will send data with less than
5 min. difference. As gateways are not connected, we know that
we alternately receive newer and older data. With
router_rate_limit_list, some of this data has been discarded
before its "age" was evaluated. This caused an unwanted additional
dilution of data which might have caused "offline" routers not
being actually offline (for a short period)
- With KeyXchangeV1, if the second call was a little earlier, the
a big share of the data would not be "new enough" and just be
discarded
- With KeyXchangeV1, the same would happen for the order of records
varying between alfred calls, were some records would have more and
some less than 5 minutes time difference
To get rid of these issues, we remove router_rate_limit_list and
test whether the newer measures to dilute data are effective.
