IBProvider now supports free ways of NULL-processing

In new IBProvider release three ways of NULL processing are supported:

  1. using special NULL flag
  2. using type DBTYPE_NULL
  3. using Variant with VT_NULL type

Previous versions of IBProvider support only first way of NULL-processing. If client set NULL using other ways (DBTYPE_NULL, VARIANT_WITH_NULL) IBProvider raise error conversion.
