/***************************** Utility Functions ****************************/
/****************************************************************************/
/*-------------------------------------------------------------------------
* Function: construct_test_file()
*
* Purpose: This function attempts to mimic the typical "poor man's
* parallel use case in which the file is passed between
* processes, each of which open the file, write some data,
* close the file, and then pass control on to the next
* process.
*
* In this case, we create one group for each process, and
* populate it with a "zoo" of HDF5 objects selected to
* (ideally) exercise all HDF5 on disk data structures.
*
* The end result is a test file used verify that PHDF5
* can open a file with a cache image.
*
* Cycle of operation
*
* 1) Create a HDF5 file with the cache image FAPL entry.
*
* Verify that the cache is informed of the cache image
* FAPL entry.
*
* Set all cache image flags, forcing full functionality.
*
* 2) Create a data set in the file.
*
* 3) Close the file.
*
* 4) Open the file.
*
* Verify that the metadata cache is instructed to load
* the metadata cache image.
*
* 5) Create a data set in the file.
*
* 6) Close the file. If enough datasets have been created
* goto 7. Otherwise return to 4.
*
* 7) Open the file R/O.
*
* Verify that the file contains a metadata cache image
* superblock extension message.
*
* 8) Verify all data sets.
*
* Verify that the cache image has been loaded.
*
* 9) close the file.
*
* Return: void
