Changes for January 2015 CPU release (8u31) synced into FX 8u40

[Kevin Rushforth]

I have synced the OpenJFX changes from the just-released January 2015 
CPU release (8u31) into 8u40. I will sync them into 8u and 9 shortly.

Here is a webrev of the FX 8u31 changes for those who are interested in 
the changes, but don't want to wade through the 29 separate changesets I 
just pushed (most of which are tag or merge changesets).
