[svn-r7400] The vc overridden probe function is blocking.  Unless internally the allfunc mutex is released, this could lead to a deadlock.  Instead, we call iprobe in a loop, and release the mutex in the loop.

RESTART_FAIL, PROCS_DEAD.

perfectly valid flattened representations end up with one big block and do not
need an additional upper bound or lower bound.   Thanks Michael Raymond

and the unexpected callback might be called and set a NULL vc ptr to the ADI request.
This test fixes this case. Ideally, connecting to the remote endpoint and attaching
the vc ptr info should be atomic.

[svn-r7378] finally, after far too many years, map PVFS error codes to something like MPI error codes

On Blue Gene (and some other platforms) the compiler occasionally generates
suboptimal code if it guesses the likelihood of a branch incorrectly.
These macros allow us to help the compiler out in cases that it guesses
poorly.

[svn-r7366] fixed bug in spawn where a bad port caused non root processes to hang.  reviewed by goodell@

This will hopefully be helpful once MPI-3 is official.

This isn't a good test, it just helps to make sure that all 17 new
nonblocking collective functions have sensible function prototypes,
exist in the library, and don't explode when you call them with simple
arguments.

The test is currently disabled in the testlist since we will currently
always fail at runtime.

These functions build but will yield an error at runtime if invoked.
They will correctly call any collective function overrides specified in
comm_ptr->coll_fns, permitting devices to experiment with NBC
implementation before a complete implementation is available above the
ADI.

Prior to this commit, the time that MPI_Group_translate_ranks took was
dependent on the _values_ of the input ranks, the size and pattern of
group2, as well as the number of input ranks.  Now for comm_world's
group (and simple subsets thereof) the translation time only depends on
the number of ranks that are translated.

The MPI_COMM_WORLD use case is essential for tools like Scalasca that
must translate communicator ranks to canonical ranks in MPI_COMM_WORLD.

The error threshold ratio, NUM_LOOPS, or number of processes may need to
be tweaked in order to make this test pass/fail reliably on different
systems.
