osc/rdma: fix regression introduced by eed7b45db59b356f6257f3b019e77643f14f84ce

The ompi_osc_signal_outgoing was moved from ompi_osc_rdma_frag_start to frag_send
which gave correct results for the bug reproducer but hangs with simple OSC
tests. Moved the ompi_osc_signal_outgoing back and it now passes all tests.

Closes #256

We only intended to bring over the "remove
--enable-ompi-progress-threads" stuff, but instead brought over all
the stuff to enable thread locking by default (which should only be on
master, not over here on the v1.8 branch).

Hence, this commit reverts all of the above-mentioned commit *except*
the --enable-ompi-progress-threads stuff (i.e., we still leave that
stuff deleted from the v1.8 branch).
