copyright updates for 2016

Using the 'update-copyright' script from gnulib[1]:

  git ls-files | UPDATE_COPYRIGHT_HOLDER='all contributors' \
      UPDATE_COPYRIGHT_USE_INTERVALS=2 \
      xargs /path/to/gnulib/build-aux/update-copyright

We're also switching to 'GPL-3.0+' as recommended by SPDX
to be consistent with our gemspec and other metadata
(as opposed to the longer but equivalent "GPLv3 or later").
