release plan for 0.17

[David Bremner]

I have pushed a tag 0.17_rc2 which has a couple of bug fixes from
0.17_rc1.  Unless some serious bug turns up I'd like to release 0.17
next week.  People are encouraged to look at

     git shortlog 0.16..0.17_rc2

and look for missing NEWS items.  My (subjectively) edited version
follows.  (P.S. congrats to Mark Walters, who moves in to #4 in the
overall commit race, #1 for this release ;) )
