New POSIX shared memory component and other common sm enhancements. NOTE: mmap is still the default. Some highlights: o Silent component failover. o The sysv component will only be queried for selection if it is placed before the mmap component (for example, -mca mpi_common_sm sysv,posix,mmap). In the default case, sysv will never be queried/selected. o Per some on-list discussion, now unlinking mmaped file in both mmap and posix components (see: "System V Shared Memory for Open MPI: Request for Community Input and Testing" thread). o Assuming local process homogeneity with respect to all utilized shared memory facilities. That is, if one local process deems a particular shared memory facility acceptable, then ALL local processes should be able to utilize that facility. As it stands, this is an important point because one process dictates to all other local processes which common sm component will be selected based on its own, local run-time test. o Addressed some of George's code reuse concerns. This commit was SVN r23633.
