Even if compile time option SQLITE_MAX_WORKER_THREADS is set to one or greater, set the default number of worker threads to zero. Distribute data more evenly between threads in sqlite3VdbeSorterWrite() to improve performance when sorting large amounts of data. Add new test file sort2.test.

The "x IN (?)" optimization in check-ins [2ff3b25f40] and [e68b427afb] is
...
incorrect, as demonstrated by the in4-5.1 test case in this check-in.
The "COLLATE binary" that was being added to the RHS of IN was overriding
the implicit collating sequence of the LHS. This change defines the EP_Generic
expression node property that blocks all affinity or collating sequence
information in the expression subtree and adds that property to the expression
taken from RHS of the IN operator.
