Subject: [PATCH 02/19] Performance fix for FriendFeed sup interface: MySQL
 query optimizer was doing a table scan on notice; explicit subquery makes it
 run much more efficiently, only scanning items within the period under
 consideration. Standard subquery should be PostgreSQL-compatible.

Subject: [PATCH 03/19] OStatus PuSH fixes: - hub now defers subscription state
 updates until after verification, per spec - hub now supports synchronous
 verification when requested (if async is not requested after) - client now
 requests synchronous verification (it's a bit safer) - cleanup on
 subscription logging/error responses
