map: ip4-map-t more RFC compliant
When MTU is not set, ignore_df and mtu check
always returns true and packets are dropped.
This patch puts MTU checks after it was
compared with 0 and set to maximum if not set.
Added trace node.
If MTU is less than the total length value of
the IPv4 packet plus 20, the translator MUST
send an ICMPv4 "Fragmentation Needed" error message
to the IPv4 source address
