[svn-r22735] Purpose:
HDFFV-8143 Provide a routine(s) for telling the user why the library broke collective data access Description: Added H5Pget_mpio_no_collective_cause() function that retrive reasons why the collective I/O was broken during Read/Write IO access. Reasons to break collective I/O: - SET_INDEPENDENT - DATATYPE_CONVERSION - DATA_TRANSFORMS - MPIPOSIX - NOT_SIMPLE_OR_SCALAR_DATASPACES (NULL Space) - POINT_SELECTIONS - NOT_CONTIGUOUS_OR_CHUNKED_DATASET (Compact or External-Storage) - FILTERS Tested: jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE)
