Since we can't use maxuid for remote externals, automatically
maintaining the last time we got results and appending a dt:
range to the query will prevent HTTP(S) responses from getting
too big.

We could be using "rt:", but no stable release of public-inbox
supports it, yet, so we'll use dt:, instead.

By default, there's a two day fudge factor to account for MTA
downtime and delays; which is hopefully enough.  The fudge
factor may be changed per-invocation with the
--remote-fudge-factor=INTERVAL option

Since different externals can have different message transport
routes, "lastresult" entries are stored on a per-external basis.
