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
