* Function: test_sohm_size2
*
* Purpose: Tests shared object header messages using size2_helper to
* create different kinds of big messages.
*
* If close_reopen is set, closes and reopens the HDF5 file
* repeatedly while writing.
*
* This test works by first creating FCPLs with various
* parameters, then creating a standard file that includes
* every kind of message that can be shared using the helper
* function size2_helper. The test measures the size of the
* file at various points. Once all of the files have been
* generated, the test compares the measured sizes of the files.
