(almost-)freezing current master

[address@hidden]

Hey all,

To prepare for 2.18, I think we can get it out fastish, but we need to more or 
less freeze current master aside from bug fixes and documentation.  I have a 
lot of stuff on the countdown or on patch push that I'm not gonna push for a 
few months until we get 2.18 out (Ferneyhough hairpins, repeat slurs, etc.).

Is everyone comfortable adopting a similar policy?  David has suggested 
2-months as a possible time frame, which I think is possible (there are no 
egregious, unfixable bugs).  I can hold off this long on pushing big patches.  
Any longer and it starts to become tedious w/ rebasing and further work and 
whatnot, so I am way-for an almost-freeze of current master.

Cheers,
MS
