Subject: lib/common.sh: Internationalize

2017-02-15: (070092d) Import from libretools.

2017-02-19: (7c55e79) Tidy formatting (2018-01-02: erroneously
            removing newlines that had been added to avoid confusing
            xgettext).

2017-05-05: (c4d5957) Don't say "local var" and "var=$(subshell)" in
            the same command (shellcheck complains about this).

2017-09-24: Update to work with loading the message
            functions from /usr/share/makepkg/util.sh

2018-01-02: Avoid confusing xgettext.
