Subject: libremessages: add a few more message routines, and make them
 gettext-aware.

 - Don't set LANG=C in common.sh
 - Move TEXTDOMAIN stuff into common.sh; so devtools stuff will use it.
 - Add _(): Basically an alias for `gettext`, but falls back if gettext is
   not available.
 - Add panic(): First showed up in `distcc-tool`, does what it sounds like.
 - Add prose(), bullet(), and flag(): they do word wrapping and such to
   make it easy to internationalize `--help` text.
 - Teach common.mk how to make .pot files based on these routines.
