[svn-r14349] This is the first commit after branching out the feature of the filter for modifying dataset's
datatype. There seems a lot of changes. Basically, this feature allows an application to
change the datatypes of datasets. If the dataset is chunked and this filter is enabled, the
modification of the data is until new data is written to the file. If the dataset is contiguous
or compact, the data is converted immediately when H5Dmodify_dtype is called.
I've tested it on 3 platforms. But there'll be some more changes coming. There'll be more
thorough test later.
