lib/parse-sexp: support actual date queries.

Browse source 
The default argument processing overlaps somewhat with what is already
done in _notmuch_date_strings_to_query, but we can give more specific
error messages for the s-expression context.

The extra generality of _sexp_parse_range will be useful when we
implement additional range prefixes (at least 'lastmod' is needed).
