Updating VERSION for shared libs for v4.0.0

This was done after discussions with core developers about any
  potential ABI breakage for any of the libs the user directly
  links against.  Also compaitiblity tests were done using the
  ibm test suite and building with v3.1.x and running with v4.0.x
