Subject: Inform UTCP when a node is offline, so it will start connection timeouts.
X-Git-Url: http://git.meshlink.io/?p=meshlink;a=commitdiff_plain;h=cb8aedb0d1da7fc93299d8fd5005b9631364b7ee

Inform UTCP when a node is offline, so it will start connection timeouts.

When there are open channels to a node that is offline for longer than the
connection timeout, the channels will be marked closed, and callbacks will
be fired.
