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.

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.

Tos support is added as a generic grev4/grev6 parameter which can have the following values :
-inherit (outer header inherits the tos value of the inner header)
-hex value

The package supports Generic Routing Encapsulation support by registering following protocol kinds:
-gre
-gretap
-grev6
-grev6tap
Following options are valid for gre and gretap kinds:
-ipaddr
-peeraddr
-df
-mtu
-ttl
-tunlink
-zone
-ikey
-okey
-icsum
-ocsum
-iseqno
-oseqno
The gretap kind supports additionally the network option
Following options are valid for grev6 and grev6tap kinds:
-ip6addr
-peer6addr
-weakif
-mtu
-ttl
-tunlink
-zone
-ikey
-okey
-icsum
-ocsum
-iseqno
-oseqno
The grev6tap kind supports additionally the network option
Typical network config for a GREv4 tunnel :
config interface 'gre'
option peeraddr '172.16.18.240'
option mtu '1400'
option proto 'gre'
option tunlink 'wan'
option zone 'tunnel'
Typical network config for a GREv4 tap tunnel :
config interface 'gretap'
option peeraddr '195.207.5.79'
option mtu '1400'
option proto 'gretap'
option zone 'tunnel'
option tunlink 'wan'
option network 'wlan_ap'
I added myself as maintainer for the moment; feel free to change.
