calcite git commit: Various tweaks

Repository: calcite
Updated Branches:
  refs/heads/master 939c9a62b -> 310eaa001


Various tweaks

They are:
* Plug some resource leaks
* Add tests for SELECT DISTINCT ... GROUP BY (they already work)
* Fix OsAdapterTest on Windows; the 'files', 'vmstat' and 'ps' tables do not work on Windows
* In checkstyle, LICENSE and NOTICE don't need header

A pull request we forgot to close in CALCITE-1959:

Close apache/calcite#529
