RFR 8056249 Improve CompletableFuture resource usage

[Martin Buchholz]

Looks fine.
Instead of using Contributed-by: for Doug's work, you should make him the
hg "user", as is done in previous changesets.  E.g. hg import has a --user
flag.

All of jsr166 CVS src/main is ready for sync'ing with openjdk9, i.e. there
are no known bugs, even though some future improvements are on the TODO
list.
