Add debugging aid "bmsToString(Bitmapset *bms)".
This function has no direct callers at present, but it's convenient formanual use in a debugger, rather than having to inspect memory and dobit-counting in your head.In passing, get rid of useless outBitmapset() wrapper around_outBitmapset(); let's just export the function that does the work.Likewise for outToken().Ashutosh Bapat, tweaked a bit by meDiscussion: <CAFjFpRdiht8e1HTVirbubr4YzaON5iZTzFJjq909y4sU8M_6eA@mail.gmail.com>
