reused. This prevents leaving the cursor in an initialized state which
could cause problems for a subsequent OP_SeekScan opcode.
Fix for ticket [6dcbfd11cf666e21] and the OP_SeekScan optimization
of check-in [4a43430fd23f8835].

(and ticket [e39d032577df6942]) as it causes difficult affinity problems
as demonstrated by ticket [dbaf8a6820be1ece] and the original assertion fault
is no longer a factor due to countless other changes of the previous 5 years.

faster queries in some cases, for example when the RHS of the IN operator
changes for each row of a large table scan.

incorrect, as demonstrated by the in4-5.1 test case in this check-in.
The "COLLATE binary" that was being added to the RHS of IN was overriding
the implicit collating sequence of the LHS. This change defines the EP_Generic
expression node property that blocks all affinity or collating sequence
information in the expression subtree and adds that property to the expression
taken from RHS of the IN operator.

as "x==?" do to collation and affinity issues. The correct converstion should
be to "x==(+? COLLATE binary)". The current check-in fixes this problem and
provides test cases. Ticket [e39d032577df69]

statements work correctly on this corner case.
