d15f87ecfd Fix a bug in the whereRangeSkipScanEst() procedure (added by 
check-in [d09ca6d5efad3e4cfa]) where it fails to consider the possibility
of a ROWID column when computing the affinity of a table column.

6861b8a13f Ugh. Consecutive UNIQUE index entries are only distinct if the index is 
on NOT NULL columns.  So the previous version was not quite right.  This
check-in fixes the problem.

9296c18a50 Change the hex literal processing so that only the SQL parser understands 
hex literals.  Casting and coercing string literals into numeric values does
not understand hexadecimal integers.  This preserves backwards compatibility.
Also:  Throw an error on any hex literal that is too big to fit into 64 bits.

unnecessary cursor open requests sent to the B-Tree layer.

a45fdc7b1e The optimization of check-in [b67a6e33f2] does not work (it generates 
incorrect VDBE code) if an OR term is AND-ed with a constant expression.
So back that optimization out and add a test case to make sure it does not
get added back in.
