This pull request includes a series of features
1) two-sided, peer-to-peer OOB implementation;
2) new data structure for sst's completion polling thread;
3) fixes to 'sst/lf.cpp' and 'rdmc/lf_helper.cpp' to filter out invalid fi_info objects returned from fi_getinfo(), which failed to respect the domain requirement in hints.
