Merge pull request #901 in HDFFV/hdf5 from ~BMRIBLER/version_bounds_bmr:develop to develop

tests for version bounds.

* commit 'f05f9d4cffab5e008c67e19034c1b248e1b01b3c':
  Miscellaneous test fixes Description:     - dtypes.c: added the use of highest version of nested datatypes to       verify the datatype's version.     - miscellaneous typos Platforms tested:     Linux/64 (jelly)     Darwin (osx1010test)
  Added h5repack tests Description:     Added tests SUPERBLOCK and INVALIDBOUNDS, composed by ADB. Platforms tested:     Linux/64 (jelly) - cmake
  Added bounds_latest_latest.h5
  Misc improvement Description:     - Added test file for h5repack test VERIFY_INVALIDBOUNDS     - Updated MANIFEST     - Removed unnecessary header file in test     - Update h5repack script to copy the new file to the test location Platforms tested:     Linux/64 (jelly)     Darwin (osx1010test)
  Improving tests Description:     - Added test for version bounds with nested datatypes     - Added script for additional version bound test in h5repack     - Cleaned up tests for consistency     - Removed extra included header files Platforms tested:     Linux/64 (jelly)     Linux/64 (moohan)     Darwin (osx1010test)
