H5Ztrans: (feature) Improved H5Z_xform_noop() and H5Z_xform_create() … (#933) (#1008)
* H5Ztrans: (feature) Improved H5Z_xform_noop() and H5Z_xform_create() function - Made a small improvement for H5Z_xform_noop() function. Now, the function will also return TRUE if the data transform function expression = "x". For this case, the HDF5 library behaves in a similar fashion as the case when no data transform function has been specified. - Improved the inline documentation of the function H5Z_xform_create() such it is more inline with the rest of the code. * Committing clang-format changes * H5Ztrans: (feature) Added 3 tests for improved H5Z_xform_noop() function - Added serial test with data transform expression = "x" to verify the improved H5Z_xform_noop() function behaves as expected. - Added 2 parallel tests with data transform expression = "x" in combination with a filter. Before, these tests will fail but with the improved H5Z_xform_noop() function they work and result in the expected behavior. - Small bug fix for one of parallel filter tests. * Committing clang-format changes * H5Ztrans: (feature) Added release note about detection of the simple data transform function "x". - Added a brief explanation about the implemented improvement of the detection of the simple data transform function "x" to the RELEASE.txt file.
