This patch is provided by Tahsin Kurc, which upgrades ADIOS file format from BP4 to BP5. Additionally, there are some code changes to use a subset of tasks as ADIOS I/O nodes along with buffer merging to improve the write performance of ADIOS type. MPI_COMM_NULL (instead of NULL) is now utilized to initialize or free those MPI comms used by ADIOS type.

PIO_MAX_ADIOS_DECOMPS: maximum number of decompositions registered with ADIOS type (default value is 64K) PIO_MAX_CACHED_STEPS_FOR_ADIOS: maximum number of cached application steps for ADIOS type (default value is 128) Until ADIOS end step is called, data will be cached in memory. It may be necessary to reduce PIO_MAX_CACHED_STEPS_FOR_ADIOS for large runs on machines with relatively small amount of memory.
