[svn-r16286] - h5repack: When user doesn't specify a chunk size, h5repack now defines a default
chunk size as the same size of the size of the hyperslab used to read the chunks.
The size of the hyperslabs are defined as the size of each dimension or a
predefined constant, whatever is smaller. This assures that the chunk
read fits in the chunk cache. (PVN - 2008/11/21)
- H5Dset_extent: when shrinking dimensions, some chunks were not deleted.
Shrinking to a zero size dimension caused an assertion in the library.
