[svn-r12252] Purpose: Maintenance

Description: Brought VMS changes back (very minor):
             In tfile.cpp file some tests for open and creation should fail on UNIX,
             but this is not true on VMS since it has versioning of the files.
             In dsets.cpp std::count was used, but it is not available on VMS; also
             VMS didn't like "bogus" name for the filter function.


Solution: Used H5_HAVE_FILE_VERSIONS and H5_VMS variables to control the tests;
          replaced "bogus" function with "filter_bogus" function

Platforms tested: VMS server, heping
