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

  $ hg init
  $ mkdir a
  $ echo a > a/b
  $ hg ci -Am m
  adding a/b

  $ hg rm a
  removing a/b (glob)
  $ hg ci -m m a

  $ mkdir a b
  $ echo a > a/b
  $ hg ci -Am m
  adding a/b

  $ hg rm a
  removing a/b (glob)
  $ cd b

Relative delete:

  $ hg ci -m m ../a

  $ cd ..
