* Implement support for loading of Virtual File Drivers as plugins Fix plugin caching for VOL connector and VFD plugins Fix plugin iteration to skip paths that can't be opened * Enable dynamic loading of VFDs with HDF5_DRIVER environment variable * Temporarily disable error reporting during H5F_open double file open * Default to using HDstat in h5_get_file_size for unknown VFDs * Use macros for some environment variables that HDF5 interprets * Update "null" and "ctl testing" VFDs
