Merge pull request #2145 in HDFFV/hdf5 from ~DEROBINS/hdf5_der:hdf5_1_12 to hdf5_1_12 * commit 'd1c07a5a6f1653ed9abd37b319e210853be9b68d': Minor tweaks noticed while going over VOL documentation. Yanked -Wc++-compat from the flags used to build the C library in both the Autotools and CMake. Fixed missing blob callbacks in test VOL connectors. Trivial parameter renaming in VOL API calls.
