A recent update documented extension headers; although none currently exist, it documents the semantics for extension headers that don't exist, allowing some to be skipped while requiring that others cause the connection to be closed. Humboldt does not currently support these, and unknown protocol numbers cause the connection to be closed. It should be updated to accept and discard unknown extension headers that are ignorable.

A binary YAML node may be used for storing the Humboldt node ID in the state file in the future.

Right now, we make no attempt to detect duplication for endpoint configuration, endpoint advertisements, or networks; this should at least be attempted and duplicates warned about.

Humboldt needs to know exactly what addresses it has opened sockets for, so it can generate proper advertisements for peers. Right now, if someone specifies no endpoints, Humboldt is unable to generate a reasonable default. Additionally, if someone were to specify an all-zeros IPv4 or IPv6 address, Humboldt would gladly open them directly. This should be substituted with behavior that determines what addresses are available on the system at runtime and opens individual ports for each. This should also result in appropriate modifications to the endpoint advertisements to be distributed.

Right now, configuration is read directly with no attempt made to handle duplications or the case of reloading the configuration. We should support reloading the configuration and appropriately handling deltas between the original configuration and the new configuration, such as opening added endpoints, removing removed endpoints, etc.
