query: Rework querying/threading machinery

Browse Source 
Rewrite the query machinery in c++:
- use an MSet decorator instead of the mu-msg-iter stuff
- use mu-query-decider to mark duplicates/unreadable/related messages
- use mu-query-threader to replace the older container/thread code

Algorithm did not substantially change, but the implementation details
did.
