Merge pull request #770 in HDFFV/hdf5 from ~NFORTNE2/hdf5_naf:develop to develop
* commit 'bca20b40b4966552a844051c3d912d6aec50592f': Initialize hid_t variables in test_Attr_bug9. Fix HDFFV-10274. When deleting all (or almost all) of the messages in an object header chunk, where the total amount deleted was greater than 64K, an error would occur due to an off by one error in the code that handled that case. Fixed this and added a test case.

/****************************************************************
**
+** test_attr_bug9(): Test basic H5A (attribute) code.
+** (Really tests object header code).
+** Tests adding several large attributes to an object until
+** they convert to dense storage. The total size of all
+** attributes is larger than 64K, causing the internal
+** object header code to, after merging the deleted
+** messages in to a NULL message, shrink the object header
+** chunk. Do this twice: once with only attributes in the
+** object header chunk and once with a (small) soft link in
+** the chunk as well. In both cases, the shrunk chunk will
+** initally be too small and a new NULL message must be
+** created.
