Merging in latest from upstream (HDFFV/hdf5:refs/heads/develop)
* commit 'a7fb4ede8601e135433ef2d23bf4bbb466d9f58d':
Fix bug in "nooptype" decode in fix for TALOS-0177.
Change check for number of dimensions for old-style arrays in datatype decoding routine from an assertion to an if/HGOTO_ERROR check, since it is inappropriate to assert the contents of a file will be what we expect.
Fix issues in H5Znbit.c where the decompression algorithm would not check the compressed data for validity, potentially causing a buffer overflow.
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.
