8b174f2916 Fix integrity_check so that it verifies NOT NULL constraints even for tables 
that have no indexes.  Enhance quick_check so that it verifies NOT NULL and
CHECK constraints.

33bec3f5e8 Enhance the Index and Table objects so that they remember if their stats come 
from the sqlite_stat1 table.  Make the "PRAGMA stats" an SQLITE_DEBUG only
pragma.  Add the flags column to "PRAGMA stats".  These are all preliminary
steps toward a "PRAGMA analyze_ifneeded;" feature.

external data sources that do not have a convenient way of computing a unique
rowid.  The current check-in almost works, but there are still serious issues.
