Merging in latest from upstream (HDFFV/hdf5:refs/heads/develop)

* commit '66a94df13b3801547523f1ea90bc84fe2ee6824b':
  Removed UIUC from copyright, added helpful comment.
  Updated MANIFEST
  Added a config file for ARM (Tested on a Raspberry Pi 3B+ w/ gcc 6).
  Tidying from code review.
  Fixed stack and frame size warnings. Not complete, but fixes most of the easier cases.
