misc: update year in copyright lines

This patch also makes some expected output lines in tests glob-ed for
persistence of them.

BTW, files below aren't yet changed in 2017, but this patch also
updates copyright of them, because:

    - mercurial/help/hg.1.txt

      almost all of "man hg" output comes from online help of hg
      command, and is already changed in 2017

    - mercurial/help/hgignore.5.txt
    - mercurial/help/hgrc.5

      "copyright 2005-201X Matt Mackall" in them mentions about
      copyright of Mercurial itself

#require test-repo

Enable obsolescence to avoid the warning issue when obsmarker are found

  $ . "$TESTDIR/helpers-testrepo.sh"

Go back in the hg repo

  $ cd $TESTDIR/..

  $ for node in `hg log --rev 'not public() and ::. and not desc("# no-check-commit")' --template '{node|short}\n'`; do
  >    hg export $node | contrib/check-commit > ${TESTTMP}/check-commit.out
  >    if [ $? -ne 0 ]; then
  >        echo "Revision $node does not comply with rules"
  >        echo '------------------------------------------------------'
  >        cat ${TESTTMP}/check-commit.out
  >        echo
  >   fi
  > done
