threading: enable filtering of server-side threads

This patch enables the filtering of a threaded view which uses
server-built threads. Filtering is done server-side, in order to
preserve the use of server-built threads.

In adding this feature, the filtering of notmuch folders was brought up
to feature parity with the other workers. The filters function the same
(ie: they can be stacked). The notmuch filters, however, still use
notmuch syntax for the filtering.

 Others are slightly different in semantics and mentioned below:
 
 *cf* <notmuch query>
-	The change folder command allows for arbitrary notmuch queries and should
-	usually be preferred over *:filter* as it will be much faster if you use

+*filter* <notmuch query>
+	The filter command for notmuch backends takes in arbitrary notmuch queries.
+	It applies the query on the set of messages shown in the message list. This
+	can be used to perform successive filters/queries. It is equivalent to
+	performing a set of queries concatenated with "and"
