ResultSet move incorrectly closes input clob

[mrotteveel]

A ResultSet move (e.g. next()) closes the current clob of FBLongVarcharField, even if it was returned to the caller. Same probably goes for clobs returned from CallableStatement. That behaviour is incorrect, a clob that was returned to the caller should live until explicitly freed or until transaction end. Only output clobs, or clobs used internally for other methods of the field should be closed.

Earlier this ticket said it affected blobs as well, but that is not entirely correct. Blobs from fields that are not SUB_TYPE TEXT are explicitly detached before they are returned, only columns of SUB_TYPE TEXT are affected, both getClob and getBlob, when auto-commit is disabled.
