RFR Mercurial trees extension: Fixes for hg 4.2-4.5

[Martin Buchholz]

Hi Mark,

These changes to trees have not made it into
http://hg.openjdk.java.net/code-tools/trees/
This is becoming a problem because mercurial 4.5.3 is the default on Ubuntu
18.04 LTS (and debian testing).

Upstream mercurial API churn continues, and there is an additional recent
upstream commit that will have to be dealt with (Google might contribute a
fix)
https://www.mercurial-scm.org/repo/hg/rev/54435fd09f1d

trees is less useful than it used to be, given that jdk10+ will not need
it.  But we'll have to deal with jdk8u for another few years.

Thanks.
