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 ds-lite connectivity.
Therefore drop the default encaplimit value for ds-lite 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 ds-lite 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.

Quote resolveip hostname argument to avoid bad shell injections.
While at it fix pattern match logic in case multiple IPv6 addresses
are returned for a hostname as they're seperated by newline by
resolveip and not a white space

If the first resolveip call will fail, peeraddr will be now empty, and
the subsequent resolveip call will try to resolve an empty string.
Fix this by storing the result in a temporary variable.
