IPv6 protocol is enabled on all gre interfaces, but gre(v6)tap
interfaces are usually added to a bridge interface, in which case
IPv6 should be enabled only on the bridge interface.

It is not always necessary to add a host route for the gre peer address.
This introduces a new config option 'nohostroute' (similar to the
option introduced for wireguard in d8e2e19) to allow to disable
the creation of those routes explicitely.

There are two problems with this behaviour that the zone is set to wan
if no zone config option is defined in the interface section.
* The zone for the interface is "normally" specified in the firewall
config file. So if we have defined "no" zone for this interface zone
option is set now to "wan" additonaly if we add the interface in the firewall
config section to the "lan" zone, the interface is added to lan and wan at once.
iptables-save | grep <iface>
This is not what I expect.
* If I do not want to set a zone to this interface it is not possible.
Remove the default assigment to wan if no zone option is defined.
If some one need the option it stil possible to define this option.

Make inclusion of the destination option header containing the tunnel
encapsulation limit configurable for IPv6 GRE packets.
Setting the uci parameter encaplimit to ignore; allows to disable the
insertion of the destination option header in the IPv6 GRE packets.
Otherwise the tunnel encapsulation limit value can be set to a value
from 0 till 255 by setting the encaplimit uci parameter accordingly.

The split-up into packages gre, grev4 and grev6 causes confusion for the
users as reported in FS#1399.
As IPv4 and IPv6 are considered now as bundled; squash the grev4 and grev6
packages into the gre package and let gre provide both grev4 and grev6.

This commit modifies the /lib/netifd/proto/gre.sh script so that, when
GRE-TAP tunnels are created, either IPv4 or IPv6, the prefix before the chosen
interface name contains the "tap" substring, to differentiate them from non-TAP
GRE tunnels.
Right now, both GRE and GRE-TAP tunnel (either IPv4 or IPv6) interfaces defined
in /etc/config/network are named equally ("gre-"+$ifname or "grev6"+$ifname)
upon creation. For instance, the following tunnels:
config interface 'tuna'
option peeraddr '172.30.22.1'
option proto 'gre'
config interface 'tunb'
option peeraddr '192.168.233.4'
option proto 'gretap'
config interface 'tunc'
option peer6addr 'fdc5:7c9e:e93d:45af::1'
option proto 'grev6'
config interface 'tund'
option peer6addr 'fdc0:6071:1348:31ff::2'
option proto 'grev6tap'
are named, respectively, "gre-tuna", "gre-tunb", "grev6-tunc" and "grev6-tund".
The current change makes that each GRE tunnel interface of the four different
types available (gre, gretap, grev6 and grev6tap) gets a different prefix.
Therefore, the abovementioned tunnels will be named, respectively:
"gre4-tuna", "gre4t-tunb", "gre6-tunc" and "gre6t-tund".
This is coherent with other types of virtual interfaces (i.e. PPP, PPPoE, PPPoA)
where the whole protocol name is used. For instance, a PPPoA interface named
"p1" and a PPPoE interface named "p2" will respectively appear as "pppoa-p1"
and "pppoe-p2", not as "ppp-p1" and "ppp-p2").
Since Linux interfaces names are limited to 15 characters, these prefixes leave,
for the worst case (TAP tunnels), 9 characters for the actual name.

Build seems to fail with:

After adding an empty install rule, the failure goes away.

UCI paramater multicast is added which allows to toggle multicast support on gre interfaces.
By default multicast support is enabled as gre tunnels are often used in combination with
routing protocols using multicast.
