Merge of recent develop work to 1.10 branch:

* H5FD_FEAT_DEFAULT_VFD_COMPATIBLE VFD feature flag (HDFFV-10214)
* H5FDdriver_query() API call (HDFFV-10215)
* Fix to skip SWMR tests that when the current VFD is not compatible
  with the default VFD (HDFFV-10197)
* Removed obsolete compiler versions from config/gnu-flags (HDFFV-9937)
* Many warning fixes
