Request approval: 8030681 & 8038435 & 8039990 & 8041151 & 8042417: hgforest.sh sync to Java 9

[Mike Duigou]

Hello;

I would like to request approval to backport a number of updates to the hgforest.sh script from JDK9. Other than expected changes related to the repositories included in the forest the result is identical to the JDK9 version.
