Merge pull request #1676 in HDFFV/hdf5 from ~KOZIOL/hdf5:refactor_obj_create_params to develop

* commit '53ffbf4bf89350b5d6b90c11585f39af94209754':
  Cast enum to int, for strict varargs handling.
  Refactor group creation parameters to take them out of the group creation property list and pass them as normal function parameters.
  Warning cleanup
  Refactor link creation parameters from being passing as properties in the link creation property list to vararg function parameters.
  Minor cleanups
  Refactor attribute creation parameters to move parameters out of creation property list and into function parameters.
  A few minor cleanups
  Refactor dataset creation parameters out of the dataset creation property list and pass them as regular function parameters.
