Merge pull request #548 in HDFFV/hdf5 from ~DEROBINS/hdf5_der:compat_feature_flag to develop
* commit '13d3d4bd0e0b799aa9c3a9b45e445d1f52294d47':
Added feature flag checks for a few other VFDs in test/vfd.c.
* Added new public H5FDdriver_query() API call. * Changed return type of H5FD_driver_query() to herr_t. * Updated swmr.c to use H5FDdriver_query() instead of the private call. * Added some flags tests to vfd.c.
* Made H5FD_driver_query() a private function instead of static. * Moved H5FD_driver_query() to H5FDint.c. * Minor typo fixes in H5I.c. * Updated swmr.c to check the VFD feature flags and skip the retries test when the VFD is not compatible with H5P_DEFAULT.
Initialized IDs to -1 and minor code tidy.
Fixed HDFFV-10214: * Updated comments in the library to accurately reflect the semantics of the H5FD_FEAT_POSIX_COMPAT_HANDLE flag. * Removed the check for the POSIX compatible handle feature flag when determining if a VFD supports SWMR. Partial work for HDFFV-10197: * Added a new H5FD_FEAT_DEFAULT_VFD_COMPATIBLE feature flag that is set when a VFD creates output that is compatible with the default VFD. Will be used in the testing but might also be generally useful to users.
