* commit '3f081c99376ad562dcb6bbf7d6c11216f682aca7':
Modifications based on PR review feedback.
Add two routines gen_ref_files() and gen_sel_files() to generate test files related to references and selections. These test files will be copied to 1.12, 1.10 and 1.8 for compatibility testing.
* commit '4830a1796441abbb5a4fbd2cff9a651f2a0d066e':
Updated tools dump output when dataset offset is undefined.
Added checks for native optional call support in some of the tools.
Misc changes for h5dump VOL changes.

* commit 'bae05235a2d87acb0d6b3a2e1c32f3b6f48cf203':
Changed default dataset shared struct to initialize hid_t IDs to H5I_INVALID_HID.
A fix in the cleaning up code for datatype when datatype initialization via H5D__init_type() fails. This is triggered by the tests for revised references when the libver bounds setting does not allow version 4 datatype message to be created. The test failure is abort core dumped. This is due to the datatype initialization fails before the datatype ID is registered. The datatype cleanup code should provide for the above situation. The code to fix the problem is the same as what is done in H5D__open_oid().
Remove tongue-in-cheek credit for Rusty Shackleford and Dale Alvin Gribble.
