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
