different processes have requested different levels of thread support. This
verification is restricted to MPI_COMM_WORLD.
In case one ore more processes have requested support for MPI_THREAD_MULTIPLE,
the cid selection algorithm will fall back to the original, thread safe
approach. Else, it uses the block-algorithm.
For dynamic communicators, we always fall back now to the original algorithm.
This has been tested for homogeneous and heterogeneous settings for
MCW. However, I could not test yet the dynamic comm scenario for technical
reasons, and that's why I don't close yet ticket 1949.

- removed OTF python bindings
(a working version of the OTF python bindings are available in the latest stand-alone release;
see http://www.tu-dresden.de/zih/otf/)
- incremented OTF version number

- poll FIFO occasionally even if just sending messages
- retry pending sends more often
- just before trying a new send
- as part of mca_btl_sm_component_progress
Maintain two new mca_btl_sm_component variables, num_outstanding_frags
and num_pending_sends, to keep overhead low.
Drain only one message fragment from the FIFO per btl_sm_component_progress
call (rather than drain until empty, which in retrospect everyone considers
to have been a mistake).

prepare the send buffer, and post the collective order to the local daemon. It
then register the callback and return fromthe modex exchange. It will only
wait for this modex completion when the modex_recv is called. Meanwhile, the
daemon will do the allgather.
This commit was SVN r21543.
Add two options for plm process module, i.e. remote_env_prefix for getting OMPI prefix on remote computer by reading its user environment variable (OPENMPI_HOME), and remote_reg_prefix is similar, but it reads the registry on the remote computer. Reading remote env prefix has a higher priority than reading reg prefix, so that user can use their own installation of OMPI.
