bbde018230 Code simplification: ALTER TABLE ADD COLUMN always upgrades the file_format 
to 4 if is not there already.  No need to upgrade to only 2 or 3 since format
4 has now been supported for over 10 years.

2fade2f791 Make sure every co-routines has its own set of temporary registers and does 
not share temporaries, since a co-routine might expect the content of a
temporary register to be preserved across an OP_Yield.
Proposed fix for ticket [d06a25c84454a].

6d258995e6 Refinements to synchronous logic:

(3) Count xDelete syncs during testing
(4) Fix #ifs on SQLITE_EXTRA_DURABLE so that directory syncs on journal
unlink are off by default.
