68a494c06f Fix a problem causing SQLite to return false "foreign key violation" errors 
when there is a partial (i.e. WHERE constrained) UNIQUE index on the parent
key columns. This bug did not cause SQLite to allow illegal data to be
inserted into the database, only to reject legal operations.

d76a902c87 Further changes to the date/time functions to suppress harmless signed

3edb157e23 The documentation says that the built-in date-time functions give undefined 
results for dates before 0000-01-01 and after 9999-12-31.  Change the
actually implementation so that the answer given is really NULL.  This also
avoids unnecessary hand-wringing over an signed integer overflow that might
otherwise occur when processing out-of-bound dates.
