Please review changes for JDK-8012975: Remove rhino from jdk8

[A. Sundararajan]

Hi,

Oracle JDK includes Rhino based javax.script implementation (which lives 
mostly in "closed" code). Rhino is being removed from Oracle JDK builds 
and there are the changes to the jdk open repository as well like 
com.sun.script.javascript package, makefiles etc. Please review the open 
jdk changes here:

Thanks,
