Features and Bug fixes in updates

MPT 4.0.0
Features:
* The MPICH2 version which this MPI is based was upgraded from version
1.0.6p1 to 1.1.1p1 and contains the following main features:
- MPI 2.1 Standard support (except dynamic process management)
- MPI-IO supports MPI_Type_create_resized and
MPI_Type_create_index_block datatypes
- Many bug fixes from ANL

* Faster MPI_Allgatherv below 2KB msgs
(10x - 2000x faster based on runs up to 96K pes)

* Faster MPI_Scatterv above 2KB msgs (20% - 80% faster)

* Improved shmem_clear_lock (4x improvement)

* Added SHMEM_ABORT_ON_ERROR env variable for SHMEM programs

* Medium Memory Model is now supported when using the shared libraries
(exception is for the CCE compiler which is planned for a future
release)

* Intel MPI header file compatibility - Initial step in providing
binary compatibility with Intel MPI built applications

* The Process Manager Interface (PMI) which is used to launch MPI
and SHMEM applications is now released as a separate product
