892ffcc7fc Fix the query planner so that it is able to use the integer primary key 
from an index as part of a multi-column constraint.

f9c8ce3ced Standardize the error messages generated by constraint failures to a format 
of "$TYPE constraint failed: $DETAIL".  This involves many changes to the
expected output of test cases.

3f4d1d1b02 Attempt to use a covering index even on a full table scan, under the theory 
that the index will be smaller and require less disk I/O and thus be faster.

21de2e755c When using an index to scan a database table, read column data from the index in preference to the table. This increases the likelihood that the table will not be required at all. (CVS 4580)

ed717fe3b2 Enhance the "PRAGMA integrity_check" command to verify that all indices are 
correctly constructed.  New calls to integrity_check are made in the test
suite. These changes are intended to prevent any future problems such
as seen in ticket #334. (CVS 1024)

e1e68f4974 When an attempt is made to insert an explicit NULL into an INTEGER 
PRIMARY KEY column, automatically convert the NULL value into a unique
integer key.  This was already happening when an implied NULL was
inserted - when the INTEGER PRIMARY KEY column was omitted from the
list of columns being inserted.  Patches from Christian Werner. (CVS 510)
