6976c2123b In the command-line shell, in CSV output mode, terminate rows with CRNL but 
do not expand NL characters in data into CRNL.  Provide the extra -newline
command-line option and the extra argument to .separator to designate an
alternative newline character sequence for CSV output.

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.

3526319b48 Add the OP_ReopenIdx opcode that works like OP_OpenRead except that it becomes 
a no-op if the cursor is already open on the same index.  Update the
OR-optimization logic to make use of OP_ReopenIdx in order to avoid
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.
