[PATCH v2 0/6] secnet: Do resolution on peer-initiated key setup too

[Ian Jackson]

This is a revised version of my series to improve secnet's behaviour
when one end is multihomed and not configured to bind to a particular
IP address, particularly when mobile peers are involved.

There were reentrancy bugs in v1 of the series, ultimately relating to
the fact that resolver->request might make the callback reentrantly.

 + 1/6 site: Document some reentrancy hazards in comments
   2/6 site: Fix bugs when resolver request submission fails
 * 3/6 site: Explicitly track name resolution status
   4/6 site: Make local_mobile be a site state variable
 + 5/6 site: Log when resolution completes
 * 6/6 site: Do name resolution on peer-initiated key setup too

+ means new patch in this version of the series
* means modifed since previous version of the series
