[PATCH 2/6] lib: replace n_query_search_threads with status returning version

[David Bremner <david@tethera.net>]

This function was deprecated in notmuch 0.21. We finally remove the
deprecated API, and rename the status returning version to the simpler
name. The status returning is kept as a deprecated alias.
