[svn-r8488] Purpose:
Bug fix. Description: Fixed handling of trivial data transform expressions (like 5/3 + 3) and some data coversion fixes. Also added more tests to dtransform.c Solution: Added some more checks in the H5Z_xform_reduce_tree function to see if perhaps the transform expression is complicated and is a non-trivial reduction. Added tests for data conversion to dtransform as well as tests for a trivial data transform expression. Platforms tested: h5committest'ed, except used arabica instead of sol and didn't do on copper b/c no logon there. Problem noted with mtime test...doesn't appear to be related to anything having to do with data transforms.
