(4) Fix #ifs on SQLITE_EXTRA_DURABLE so that directory syncs on journal
unlink are off by default.

81028a455d The former sqlite3ResetInternalSchema() routine was really two different 
routines, selected by parameter, each with a confused mission.  So split
this routine up into three separate smaller routines, calling each
separately as needed.  Hopefully this will make further refactoring and
schema reset collateral damage containment easier.

c7792fa052 Begin a series of changes designed to reduce the scope and frequency of 
invalidating schemas.  Design goals are that the internal schema should
never be deleted out from under a prepared statement that is running and
that all prepared statements should be expired if the schema is invalidated.
At the same time, minimize the number of schema invalidations.  This change
merely revises the sqlite3ResetInternalSchema() function to use -1 as the
wildcard for "all" rather than 0, so that we can reset the main schema
independently of all the others.
