Jira TRILAB-45

* commit 'f54fb420d08ea0a7e7b026150c0ab559803e0acd': (34 commits)
  Specify variable type. Remove unnecessary whitespace.
  OHDR tests now accept h5_fileaccess() fapls. Formatting, informative comments, and minor renaming.
  Fix some CMake listings
  Add error checking to the minimized dset header size calculation. Update printf->HDprintf statements.
  Remove `#if 0` block of deprecated code.
  Fix mistake with H5E_BEGIN_TRY {...} H5E_END_TRY block containing ERROR-raising macros. Formatting tweaks.
  Add "compact" storage test to relative header size comparisons.
  Formatting adjustments.
  Formatting adjustments
  Move H5Fset_dset_no_attrs_hint VOL operations to native. Move minimzied object header tests from separate file to test/ohdr.c Some formatting changes.
  Re-format test/ohdr_mindset.c Fix a few transcription errors in other test files.
  formatting adjustments
  Reformat to be more consistent with existing code. Fix a few typos.
  add missing paramter - macro seemingly unused, but absence results in compiler complaint
  fix reference; move declaration in file
  Remove unused debugging print in '#if 0' block
  Fix typo. Fix CHECK of wrong ID (dset[2|3]_id).
  change test file name and apply 'h5_fixname' to it
  Sidestep and hide&flag minor issues causing test failures.
  Incorporate minimized dset ohdr tests into extant suite.
