A component with implementation of R. Rabenseifner's algorithm for Reduce and Allreduce.
This algorithm is a combination of a reduce-scatter implemented with recursive vector halving
and recursive distance doubling, followed either by a gather or an allgather.
Current limitations:
-- count >= 2^{\floor{\log_2 p}}
-- commutative operations only
-- intra-communicators onl

coll/spacc: Modify implementation to use `ompi_coll_base_sendrecv()`
Replace irecv() + isend() + ompi_request_wait() to ompi_coll_base_sendrecv().
