This now passes the loop test, and so we believe it resolves the random hangs in finalize.
Changes in PMIx master that are included here:
* Fixed a bug in the PMIx_Get logic
* Fixed self-notification procedure
* Made pmix_output functions thread safe
* Fixed a number of thread safety issues
* Updated configury to use 'uname -n' when hostname is unavailable
Work on cleaning up the event handler thread safety problem
Rarely used functions, but protect them anyway
Fix the last part of the intercomm problem
Ensure we don't cover any PMIx calls with the framework-level lock.
Protect against NULL argv comm_spawn

make NBC_Handle (almost) an internal structure created
by NBC_Schedule_request()
use a local variable instead of what was previously handle->tmpbuf

update the cartesian communicator based grouping strategy to match the other
algorithms used in the aggregator selection process.
Signed-off-by: Edgar Gabriel <egabriel@central.uh.edu>
the cart_based_grouping aggregator strategy was not correctly updated
during the last major rewrite of the aggregator selection algorithm.
It is also not supposed to be called from file_open (but from
file_set_view).

the 'hostname' command might not be available on some platforms
such as Fedora Core 26, so mimick config/libtool.m4 and fallback
to 'uname -n' if needed

* Add work around support for the following missing ops in ROMIO 3.1.4

- `MPI_File_iwrite_all`

This commit adds code to allow support for the info assertions added
by mpi-forum/mpi-issues#11. The assertions added are:
mpi_assert_no_any_tag, mpi_assert_no_any_source,
mpi_assert_exact_length, and mpi_assert_allow_overtaking.
This commit also adds support for the mpi_assert_no_any_source and
mpi_assert_allow_overtaking info keys to the ob1 pml.

Hostname and PID are output as a message prefix in many places in
our code. Their printf-formats were either `[%s:%d]` or `[%s:%05d]`.
This commit changes `[%s:%d]` to `[%s:%05d]`. The latter was more
widely used in our code (including OPAL output system and the signal
handler).

This commit expands the effect of the MCA parameter `opal_abort_delay`
to the OPAL signal handler. This allows attaching of a debugger on
segmentation fault etc. before quitting the job.
The sleep code is moved to the `opal_delay_abort` function from the
`ompi_mpi_abort` and `oshmem_shmem_abort` functions for code cleanup.

Example (using MPI_ORDER_C so the below has 6 rows of 4 ints to parcel out)
size = 4;
rank = 0;
ndims=2;
gsizes[0] = 6;
gsizes[1] = 4;
distribs[0] = MPI_DISTRIBUTE_CYCLIC;
distribs[1] = MPI_DISTRIBUTE_BLOCK;
dargs[0] = 2;
dargs[1] = 2;
psizes[0] = 2;
psizes[1] = 2;
MPI_Type_create_darray(size, rank, ndims,
gsizes, distribs, dargs, psizes,
MPI_ORDER_C, MPI_INT, &mydt);
Expectation for the layout:
inner dimension (1) is
4 items (ints) distributed block over 2 ranks with 2 items each
eg for rank 0: [ x x . . ]
outer dimension (0) is:
6 items (the above [ x x . .]) cyclic over 2 ranks with 2 items each
eg for rank 0:
[ x x . . ] : offset=0 bytes=8
[ x x . . ] : ofset=16 bytes=8
[ . . . . ]
[ . . . . ]
[ x x . . ] : offset=64 bytes=8
[ x x . . ] : offset=80 bytes=8
Or more specifically a stream of ints 0,1,2,3,4,5,6,7 sent into that
type should be
[ 0 1 . . ]
[ 2 3 . . ]
[ . . . . ]
[ . . . . ]
[ 4 5 . . ]
[ 6 7 . . ]
The data was laying out though as
[ 0 1 2 3 ]
[ . . . . ]
[ . . . . ]
[ . . . . ]
[ 4 5 6 7 ]
[ . . . . ]
because the recursive construction inside the block() function (which
creates the smaller row datatype [ x x . . ]) wasn't setting the extent
of that type.
