implemented entirely on top of the PML. This allows us to have a one-sided interface even when we are using the CM PML and MTLs for point-to-point transport (and therefore not using the BML/BTLs) * Old pt2pt component was renamed "rdma", as it will soon be having real RDMA support added to it. Work was done in a temporary branch. Commit is the result of the merge command: svn merge -r10862:11099 https://svn.open-mpi.org/svn/ompi/tmp/bwb-osc-pt2pt This commit was SVN r11100. The following SVN revisions from the original message are invalid or inconsistent and therefore were not cross-referenced: r10862 r11099
