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

* commit '2412158ed8326a3f3d62fbd947e470667d0b5951':
  Add new file COPYING_LBNL_HDF5.
  Revert "Clear hdf5 1.10 entries from RELEASE.txt in the develop branch.  Entries"
  Add LBNL license file and modify COPYING file accordingly.
  Omnibus checkin for several relatively minor modifications:
  Clear hdf5 1.10 entries from RELEASE.txt in the develop branch.  Entries in this branch version of RELEASE.txt should be intended for the future 1.12.0 release.
  Fix HDFFV-8089 Description:     Some code within an "ifdef H5D_CHUNK_DEBUG" block was using outdated     data structure but not caught because the case of H5D_CHUNK_DEBUG being     defined was never tested.  It was commented out.     I defined H5D_CHUNK_DEBUG, tested, and commented out again. Platforms tested:     Linux/32 2.6 (jam)     Linux/64 (platypus)     Darwin (osx1010test)
