Misc: develop signal operations #94

SHMEM_PUT_SIGNAL
SHMEM_PUT_SIGNAL_NBI
SHMEM_SIGNAL_FETCH

Starting point

Section 9.8 Signaling Operations in OpenSHMEM v1.5 spec
Can use MPI_Accumulate(REPLACE) as put + MPI_FETCH_AND_OP as signal. Because MPI guarantees the ordering of accumulate operations, thus completion of FOP ensures completion of the former ACC.
