Merge pull request #60 in HDFFV/hdf5 from ~NFORTNE2/hdf5_nf:hdf5_1_8 to hdf5_1_8

* commit '4fe02fbc51944fc9fa392c8ce7e229b8781d70ab':
  Replace assertion in H5O_dtype_decode_helper for number of array dimensions with a check and error. The assertion was inappropriate because it is operating on data read from the file, which the library does not always have direct control of.
