[svn-r1210] Changed parameters for function calls which figure out the buffer size for
H5Dread/H5Dwrite to use to allow the I/O calls to break up a user's buffer into pieces that are at least as large as the sequence of bytes being written in the fastest changing dimension. Also fixed a hard-to-find bug in the hyperslab I/O routines which could cause data to be corrupted when writing out fields to compound datatype data with background preservation turned on and hyperslabs which were large enough to require two I/O passes on a hyperslab block. A pretty obscure situation, but it would be worthwhile for users to upgrade to this code in order to be certain that correct data is being written.
