Samuel Gutierrez 2fb7c344fc Added a new System V (sysv) shared memory component for Open MPI.
Configure Option:
--enable-sysv

MCA Parameter:
mpi_common_sm

mpi_common_sm accepts a comma delimited list of: [sysv],mmap (order
dependent).  The first component that is successfully selected is used. For
example, -mca mpi_common_sm sysv,mmap will first try sysv. If sysv is not
successfully selected, then mmap will be used.  mmap will be used if 
mpi_common_sm is not provided.

Notes:
Please make certain that your system's shmmax limit, or equivalent, is larger
than mpool_sm_min_size.  Otherwise, shmget may fail.
