Merge pull request #21 in ~VCHOI/my_third_fork from develop to bugfix/HDFFV-10585-investigate-slowness-of-regular

* commit '0ea77179d507bd2c29f3b9b357a0c35d4077b29c': (39 commits)
  Fix the errors when updating the versions in the new 1.13 develop branch.
  add missing version to list
  Add new versioned filename to list
  Update N_FSINFO_VERSION_BOUNDS to H5F_LIBVER_NBOUND.
  Remove file script
  Update versioning to next major version
  Update develop branch version to 1.13.0 after creation of hdf5_1_12 branch.
  Merge Binh-Minh's changes for code improvement to chunk_info.c (PR #1942) to develop branch.
  Update to current external file population.
  Revert else-if to single line.
  Fix missing option and incorrect close
  Revert "Moved NDEBUG guards to H5EA_DEBUG in H5EA package."
  Revert "Fix for H5EA debug package when built in release mode."
  Change print calls to HD-wrapped. Minor formatting tweaks (inc. regressions and in-file style-matching).
  Refactor h5repackgentest to have more modular internals, for easier addition of new tests. Update manifest and test script for new hdf5 external-storage .h5 files.
  Remove obsolete symbol
  small syntax changes
  Renamed get/set_time() calls in the tools library to avoid name clash when building static parallel HDF5 w/ static linking to OpenMPI.
  Change unused variable to generic form
  Whitespace cleanup
