[PATCH] Include application_name in "connection authorized" log message

Good afternoon, all.

In trying to troubleshoot the source of a recent connection storm, I was
frustrated to find that the app name was not included in the connection
messages. It is there in the log_line_prefix on the disconnection messages
but I would prefer it be directly visible with the connection itself. With
some guidance from Stephen Frost I've put together this patch which does
that.

It adds a new application_name field to the Port struct, stores the
application name there when processing the startup packet, and then reads
from there when logging the "connection authorized" message.

Thanks,
Don.
