[OpenJDK 2D-Dev] RFR: 8078331: Upgrade JDK to use LittleCMS 2.7

[Phil Race]

These changes are all directly from upstream LCMS.
It takes us from 2.6 plus a couple of patches to the 2.7 release with the
upstream version of those patches. Modulo 'white space' we will be
100% in sync with the LCMS current release, for perhaps the first time.

I'm running a full JPRT job to validate my local builds.
