Fixes build with glibc 2.28.

As already done with other config mode texts, the altitude field now has
default texts that are used when they are not set in the site i18n files.
The altitude-help text has been removed from site i18n; instead, the
geo-location-help text now overrides the whole section description
including the part that mentions the altitude.

Do not show by default, delete old altitude value when a form without
altitude shown is saved.

Fixes #1493

Fixes #1491

Revert "gluon-core: make sure dns traffic leaves the correct interface when there is ipv6 wan uplink"

This reverts commit b3d70111.

with this change, DNS in batman-adv based networks is broken.
although the revert breaks babel based networks, this is not as big of a problem.

removes cryptic debug messages from kernel ring buffer and
also reduces memory usage by as much as 20-25 MiB.

This device is a dual 5GHz device. It is recommended to manually change the
radio of the first device to the lower 5GHz channels and the second radio
to the upper 5GHz channels.

The commit b3762fc6 ("gluon-client-bridge: move IPv4 local subnet route
to br-client (#1312)") moves the IPv4 prefix from the local-port interface
to br-client. A client requesting an IPv4 connection to the IPv4 anycast
address of the node (the device running gluon) will create following
packets:

1. ARP packet from client to get the MAC of the mac address of the anycast
   IPv4 address
2. ARP reply from node to client with the anycast MAC address for the IPv4
   anycast address
3. IPv4 packet from client which requires reply (for example ICMP echo
   request)
4. ARP request for the client MAC address for its IPv4 address in prefix4
   (done with the mac address of br-client and transmitted over br-client)
5. IPv4 packet from node (transmitted over br-client with br-client MAC
   address) as reply for the client IPv4 packet (for example ICMP echo
   reply)

The step 4 and 5 are problematic here because packets use the node specific
MAC addresses from br-client instead of the anycast MAC address. The client
will receive the ARP packet with the node specific MAC address and change
their own neighbor IP (translation) table. This will for example break the
access to the status page to the connected device or the anycast DNS
forwarder implementation when the client roams to a different node.

This reverts commit b3762fc6 and adds an
upgrade code to remove local_node_route on on existing installations.

The commit b3762fc6 ("gluon-client-bridge: move IPv4 local subnet route
to br-client (#1312)") moves the IPv4 prefix from the local-port interface
to br-client. A client requesting an IPv4 connection to the IPv4 anycast
address of the node (the device running gluon) will create following
packets:

1. ARP packet from client to get the MAC of the mac address of the anycast
   IPv4 address
2. ARP reply from node to client with the anycast MAC address for the IPv4
   anycast address
3. IPv4 packet from client which requires reply (for example ICMP echo
   request)
4. ARP request for the client MAC address for its IPv4 address in prefix4
   (done with the mac address of br-client and transmitted over br-client)
5. IPv4 packet from node (transmitted over br-client with br-client MAC
   address) as reply for the client IPv4 packet (for example ICMP echo
   reply)

The step 4 is extremely problematic here. ARP replies with the anycast IPv4
address must not be submitted or received via bat0 - expecially not when it
contains an node specific MAC address as source. When it is still done then
the wrong MAC address is stored in the batadv DAT cache and ARP packet is
maybe even forwarded to clients. This latter is especially true for ARP
requests which are broadcast and will be flooded to the complete mesh.

Clients will see these ARP packets and change their own neighbor IP
(translation) table. They will then try to submit the packets for IPv4
anycast addresses to the complete wrong device in the mesh. This will for
example break the access to the status page to the connected device or the
anycast DNS forwarder implementation. Especially the latter causes extreme
latency when clients try to connect to server using a domain name or even
breaks the connection setup process completely. Both are caused by the
unanswered DNS requests which at first glance look like packet loss.

An node must therefore take care of:

* not transmitting ARP packets related to the anycast IPv4 address over
  bat0
* drop ARP packets related to the anycast IPv4 when they are received on
  bat0 from a still broken node
* don't accept ARP packets related to the anycast IPv4 replies on local
  node when it comes from bat0
