Merge pull request #2451 in HDFFV/hdf5 from ~VCHOI/my_third_fork:bugfix/develop_seg_fault_sel_compat to develop
* commit '81b1ed4e1724b8a6a731ab2b8fb03234a8b49d15': Fix issues when deserializing point/all/none selection with version beyond the library's supported version: (1) Verify the decoded version before proceeding further with deserialization (2) Close the dataspace if errors occurred after opening the dataspace
