Update to latest gnulib with new copyright year. Run "make update-copyright" and then... * gnulib: Update included in this commit as copyright years are the only change from the previous gnulib commit. * tests/init.sh: Sync with gnulib to pick up copyright year. * bootstrap: Likewise. * tests/sample-test: Adjust to use the single most recent year.
