This commit adds support for performing one-sided operations over supported hardware (currently Infiniband and Cray Gemini/Aries). This component is still undergoing active development. Current features: - Use network atomic operations (fadd, cswap) for implementing locking and PSCW synchronization. - Aggregate small contiguous puts. - Reduced memory footprint by storing window data (pointer, keys, etc) at the lowest rank on each node. The data is fetched as each process needs to communicate with a new peer. This is a trade-off between the performance of the first operation on a peer and the memory utilization of a window. TODO: - Add support for the accumulate_ops info key. If it is known that the same op or same op/no op is used it may be possible to use hardware atomics for fetch-and-op and compare-and-swap.
