Refinements to synchronous logic:

Browse Source 
(1) Use PAGER_SYNCHRONOUS_FULL rather than the corresponding magic number.
(2) Honor SQLITE_NO_SYNC on xDelete calls with sync
(3) Count xDelete syncs during testing
(4) Fix #ifs on SQLITE_EXTRA_DURABLE so that directory syncs on journal
unlink are off by default.
