028696c4cc Remove the SQLITE_CONFIG_WORKER_THREADS configuration parameter. The number
of worker threads in the sorter is now determined only by the
PRAGMA threads=N setting.

fad9f9a8a6 When sorting data for a CREATE INDEX statement in single-threaded mode, assume that keys are delivered to the sorter in primary key order. Also fix various comments that had fallen out of date.

578e1ca8d7 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.
