[PATCH 0/8] secnet: Log peer address on timeout

[Ian Jackson]

While debugging a problem with my secnet installations, I found that
the usual logs were rather inadequate.  Hence this series.

I intend to push this to master shortly after 0.3.1 is released.

 1/8 log: Introduce slilog_part; abolish log_if->logfn
 2/8 Makefile.in: introduce -Wunused-function
 3/8 site logging: Break out event_log_priority
 4/8 site logging: Use [v]slilog_part in slog
 5/8 site logging: introduce vslog
 6/8 site logging: Break out logtimeout
 7/8 comm: Introduce comm_addr_to_string
 8/8 site logging: Log peer addresses on timeout
