Set the protocol tree item for IPSEC-over-UDP to the length of the
IPSEC-over-UDP header - i.e., don't include the actual ISAKMP or ESP
data in that item.

Clear the Info column before dissecting.
Use "proto_tree_add_item()" to create the top-level entry - the string
used in the "proto_tree_add_protocol_format()" call was the protocol's
long name, so "proto_tree_add_item()" would use it.
Don't register the dissector by name - nobody uses it.
