[svn-r9101] Purpose:
Bug fix Description: 1 - Dataset contiguous storage cache information had a bug where it was possible to try to access invalid cache information if the cache wasn't filled the first time it attempted to loop through the list of offset/length vectors. 2 - Additionally, the contiguous storage cache information was being used in certain circumstances from the chunked dataset I/O code path, which was generally fatal since the chunk storage and contiguous storage information were stored together in a union. Solution: 1 - Avoid special case of first trip through loop over offset/length I/O vectors and always check for the contiguous storage sieve buffer buffer being NULL. 2 - Change the union containing the chunk and contiguous storage cache information into a struct, allowing both to be used at the same time. Platforms tested: FreeBSD 4.10 (sleipnir) h5committested
