Per 0ab6b201fe, note in the MPI_Comm_spawn_multiple.3in man page that
the array_of_commands does not need to be terminated -- it just need
to have exactly "count" entries. In the Fortran binding, at least,
this is different than in prior released versions of Open MPI (it's
not a backwards incompatibility, since prior versions of Open MPI
required array_of_commands to be blank-string-terminated in Fortran --
this change makes Open MPI be *less* restrictive, and therefore still
backwards compatible).

MPI defines the "argv" param to Fortran MPI_COMM_SPAWN as being
terminated by a blank string. While not precisely defined (except
through a non-binding example, Example 10.2, MPI-3.1 p382:6-29), one
can infer that the "array_of_argv" param to Fortran
MPI_COMM_SPAWN_MULTIPLE is also a set of argv, each of which are
terminated by a blank line.
The "array_of_commands" argument to Fortran MPI_COMM_SPAWN_MULTIPLE is
a little less well-defined. It is *assumed* to be of length "count"
(another parameter to MPI_COMM_SPAWN_MULTIPLE) -- and *not* be
terminated by a blank string. This is also given credence by the same
example 10.2 in MPI-3.1.
The previous code assumed that "array_of_commands" should also be
terminated by a blank line -- but per the above, this is incorrect.
Instead, we should just parse our "count" number of strings from
"array_of_commands" and *not* look for a blank line termination.
This commit separates these two cases:
* ompi_fortran_argv_blank_f2c(): parse a Fortran array of strings out
and stop when reaching a blank string.
* ompi_fortran_argv_count_f2c(): parse a Fortran array of strings out
and stop when "count" number of strings have been parsed.

The various RMA functions need to have the asynchronous property on

As discussed on https://github.com/mpi-forum/mpi-issues/issues/77#issuecomment-369663119
the conversion to double in the MPI_Wtime decrease the range
and accuracy of the resulting timer. By setting the timer to
0 at the first usage we basically maintain the accuracy for
194 days even for gettimeofday.

Per MPI 3.1 chapter 13.3 :
"Derived etypes can be constructed by using any of the MPI
datatype constructor routines, provided all resulting typemap
displacements are non-negative and monotonically nondecreasing."
Same restriction applies to ftypes.
add the OMPI_DATATYPE_CHECK_FOR_VIEW() macro that is
check the underlying opal_datatype_t is monotonic, on top
of all checks performed in OMPI_DATATYPE_CHECK_FOR_RECV().
Since checking monotoniciy is expensive, check is only performed
when needed, but the result is cached by ompi_datatype_is_monotonic().
Thanks Wei-keng Liao for the valuable feedback.
Thanks George for the guidance.

They were incorrectly changed to subroutines in only `pmpi`
in 258d1aa160.
Strictly speaking, this change involves binary incompatibility.
But nobody used these subroutines and nobody will be affected because
these subroutines were useless (didn't return a calculated value).

The current versions of these functions have a fatal flaw. If a
errhandler set and free call is made by another thread while the
thread calling get is between the cmpset and retain then we will
retain an invalid object. Fixing this by just using locking. This is
not a critical path so this should be ok.

This commit renames the atomic compare-and-swap functions to indicate

The `ompi_comm_set` function never sets `NULL` to its first argument
`ncomm`. So `NULL` check is unnecessary in its callers. Furthermore,
`NULL` check may obscure a real return code when an error occurs
if the variable is initialized to a `NULL` value.
Also, `NULL` check is added in the `ompi_comm_set` function to
avoid segmentation fault in an out-of-memory condition.

we now have 12 cases to deal (4 writers and 3 readers) :
1. C `void*` is written into the attribute value, and the value is read into a C `void*` (unity)
2. C `void*` is written, Fortran `INTEGER` is read
3. C `void*` is written, Fortran `INTEGER(KIND=MPI_ADDRESS_KIND)` is read
4. Fortran `INTEGER` is written, C `void*` is read
5. Fortran `INTEGER` is written, Fortran `INTEGER` is read (unity)
6. Fortran `INTEGER` is written, Fortran `INTEGER(KIND=MPI_ADDRESS_KIND)` is read

Passed the below set of symbols into a script that added ompi_ to them all.
Note that if processing a symbol named "foo" the script turns
foo into ompi_foo
but doesn't turn
foobar into ompi_foobar
But beyond that the script is blind to C syntax, so it hits strings and
comments etc as well as vars/functions.
