Message:

Add support for the extended-join capability

This simple implementation only advertises extended-join to downstreams
when all upstreams support it.

In the future, it could be modified so that soju buffers incoming
upstream JOINs, sends a WHO, waits for the reply, and sends an extended
join to the downstream; so that soju could advertise that capability
even when some or all upstreams do not support it. This is not the case
in this commit.
