drh 04f2e3403f Fix an incorrect assert in the virtual table logic - it could fire following 
an I/O error after sqlite3_close_v2() was added.

drh 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.

drh e485522462 Do not invoke the xRollbackTo or xRelease methods of a virtual table without 
having first invoked an appropriate xSavepoint method.  Add assert() statements

drh 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.

drh 22645842a4 The changes to fix [f7b4edece25c9948] mean that the schema is always loaded 
whenever a prepared statement is running.  This means that a couple of
branches can be eliminated and one operand of OP_ParseSchema can be removed.
