We previously attempted to use the ESCAPE clause to set the escape delimiter to
a backslash.  Unfortunately, this does not universally work on all databases,
since on databases which natively use the backslash as a delimiter, the
backslash itself needs to be delimited, but on other databases that have no
delimiter, backslashing the backslash causes an error.

So the only solution that I can come up with is to create an option in res_odbc
that explicitly specifies whether or not backslash is a native delimiter.  If
it is, we use it natively; if not, we use the ESCAPE clause to make it one.
