this commit syncs ompio related directories in v4.1.x to master. The efforts to bring the lustre performance fixes and support for external32 data representation over were too overwhelming when dealing with every single pr individually. There are a very few minor modification that had to be done for syncing: - v4.1.x does not have opal/mutex.h - v4.1.x does not have opal_atomic_int32_t datatype - the io module structure has two fewer function pointers (related to info_set/get) compared to the version on master. Tested so far with the ompio testsuite as well as hdf5-1.10.5 testsuite (testphdf5, t_shapesame, t_bigio) on an XFS file system. More tests on Lustre and BeeGFS to follow.
