lib/parse-sexp: support saved s-expression queries

It turns out there is not really much code in query-fp.cc useful for
supporting the new syntax. The code we could potentially factor out
amounts to calling notmuch_database_get_config; both the key
construction and the parsing of the results are specific to the query
syntax involved.
