Setting encaplimit to a numerical value results into the value being
included as tunnel encapsulation limit in the destination option header
for tunneled packets.
Several users have reported interop issues as not all ISPs support the
destination option header containing the tunnel encapsulation limit
resulting into broken map connectivity.
Therefore drop the default encaplimit value for map tunnels so
no destination option header is included by default.

Be compatible with ISPs which don't support the destination option header containing
the tunnel encapsulation limit as reported in FS#1501.
Setting the uci parameter encaplimit to ignore; allows to disable the insertion
of the destination option header in the map-e packets.
Otherwise the tunnel encapsulation limit value can be set to a value from 0 till 255
by setting the encaplimit uci parameter accordingly.
If no encaplimit value is specified the default value is 4 as before.

Delete the map-t device when tearing down the map-t interface; as such
there's no conflict when the map-t interface comes up again when trying
to add the map-t device as the map-t device was still present
(Can not add: device 'map-wan6_4' already exists!).
Only call ifdown in teardown for map-e and lw6o4 map interfaces types
in order to suppress the trace "wan6_4 (6652): Interface wan6_4_ not found"
