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

* Protects us from segv when ROMIO 314 is selected and one of the
following operations is called:
- MPI_File_iread_at_all
- MPI_File_iwrite_at_all
- MPI_File_iread_all
- 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.

Cleanup the way we look for matching OFI addresses by using the opal_net_samenetwork helper function. This now works for multi-network environments, but only using the socket provider

According to Section 6.4.4.1 of the C, we do not need to prepend a type
to a constant to get the right size. The compiler will infer the type
according to the number of bits in the constant.
