Merge pull request #1111 in HDFFV/hdf5 from hdf5_1_10.sync to hdf5_1_10

* commit '57f64b92d19fed2879ee9bafe1d29bfac865d54c': (30 commits)
  HDFFV-10405: Using h5fget_obj_count_f with a file id of H5F_OBJ_ALL_F does not work properly
  HDFFV-10405: Using h5fget_obj_count_f with a file id of H5F_OBJ_ALL_F does not work properly
  HDFFV-10405: Using h5fget_obj_count_f with a file id of H5F_OBJ_ALL_F does not work properly
  Cleaned up H5Fmount/unmount code.
  Normalization with vol_integration branch.
  Add fortran MPI to test and example
  Add mpi include folders for fortran C objects
  Normalization with the vol_integration branch.
  Fixed MANIFEST
  Fix usage of compression lib in shared tests
  Fix jni function call version
  Fix the error found after earlier checkin.
  H5O_info fixes for java and examples
  Added a RELASE.txt entry for HDFFV-10505.
  Changed 'deprecated' to indicate 'no longer supported' in the --enable-debug/production configure flags.
  (1) Made the change according to the pull request feedback. (2) Removed the performance test form test/th5o.c: will decide on what needs to be done to show speedup via HDFFV-10463.
  Normalize with vol_integration.
  Removed unused H5MF functions and updated FUNC_ENTER macros and naming in H5MFsection.c.
  Restored some unused #defines to the deprecated section of H5Dpublic.h.
  Changes made based on feedback from pull request #1039.
