This commit adds a new optional function to the BTL module:
btl_flush. This function takes an optional BTL endpoint. When called
this function completes all outstanding RDMA and atomic operations
started prior to the call to btl_flush.

Fixed the desync of job-nodelists between mpirun and orted
daemons. The issue was observed when using RSH launching because user
can provide arbitrary order of nodes regarding HNP placement.
The mpirun process propagate the daemon's nodelist order to nodes.
The problem was that HNP itself is assembling the nodelist based on
user provided order. As the result ranks assignment was calculated
differently on orted and mpirun.
Consider following example:
* User launches mpirun on node cn2.
* Hostlist is cn1,cn2,cn3,cn4; ppn=1
* mpirun is passing hostlist cn[2:2,1,3-4]@0(4) to orteds
So as result mpirun will assing rank 0 on cn1 while orted will assign
rank 0 on cn2 (because orted sees cn2 as the first element in the node
list)

This header file was meant to be autogenerated, and for
some reasons, was never removed from the repository.
Update .gitignore as well

If component selection fails, then module->bases might be unallocated
when ompi_osc_sm_free() in invoked, so test it before trying to free()
module->bases[0].
Thanks Martin Binder for the report.

Since open-mpi/ompi@47fd2313ab
the backing file is now in /dev/shm by default. As a consequence,
the backing file name has to include the jobid so more than one job
can run at a time.

When too much data is available on stdin, it might not be
forwarded immediatly to the task (write() might fail with -EAGAIN),
so when stdin is terminated, there might be some remaining data
to be pushed to the task. In this case, delay the release of the sink
so no data is discarded.

this option was only used by the iof/mr_hnp (aka Map/Reduce)
component that is no more part of master nor v3 branches.

an erroneous return statement has creeped in commit 1885d99
which leads to some processes not resetting stripe_size
and stripe_count correctly. This can lead in 3.0.x to different
fcoll modules being selected. The impact is not that dramatic on
master and 3.1.x, but could lead to problems as well.
