Back to work on Issue 4752: Add ly:one-page-breaking

[Paul]

Hi all,

I have some time to work again on ly:one-page-breaking.  Ideally I'd 
like to land it before 2.20 is released.  I've just updated the patches 
so they apply to current master.

James (or anyone), one possible complication was different gcc versions 
on different machines giving different results.  If you have a chance, 
would you mind testing the patches to see if this is the case?  Assuming 
there are still problems can you save and post the full log?  For me 
make still succeeds on current LilyDev (gcc 4.9.2, g++ 4.9.2, Debian 
4.9.2-10).
