Datagram Type Identification
----------------------------
The four datagram types do not share a common header with the protocol
version in the same place. Packets cannot be identified by type
based on their content. When using multiple types on the same session,
or a single type together with streaming, applications must use
protocol numbers and/or I2CP/SAM ports to route incoming packets to the
right place. Using standard protocol numbers will make this easier.
Leaving the protocol number unset (0 or PROTO_ANY), even for a datagram-only
application, is not recommended as it increases the chance of routing
errors and makes upgrades to a multi-protocol application harder.
Version fields in Datagram 2 and 3 are provided only as
an additional check for routing errors and future changes.
