Replace function copy_dataset_except_data() with function create_resized_duplicate_dataset.
    Files were found with fixed dimensions causing H5Sset_extent_simple to fail when attempting
    to increase the size of a fixed size dataset.  The new function creates a dataset in the 
    output file duplicating the characteristics of the dataset in the input file with the 
    appropriate size for the number of granules in the new aggregation. 
Remove local function reset_dataspace_extent which is no longer used.

Tested jam & koala, gcc and icc.
