An incorrectly named variable caused all pml variables to disappear
from ompi_info. This commit fixes the typo. We may add some logic into
the MCA base to catch these sorts of things in the future.

This commit fixes a segfault in mtl-portals4 finalize(). The segfault
occurs if finalize() is called without any calls to add_procs(). This
commit resolves the segfault by skipping the progress() loop in
finalize() if the Portals was not initialized.

This commit fixes a segfault in btl-portals4 add_procs(). The segfault
occurs if add_procs() is called after a del_procs() call that reduces
the proc count to zero which would cause PT and NI resources to be
freed. This commit resolves the segfault by using a common
initiailization boolean and only freeing module resources in
finalize().

Have Open MPI's PMIx component to set PMIx's "show_load_errors" to do
the same thing that Open MPI's "show_load_errors" does.

Some of the show_help() messages that were added in 40afd525f8 were
really normal / expected behavior (e.g., if 2 peers connect in the TCP
BTL more-or-less simultaneously, one of them will drop the connection
-- no need to show_help() about this; it's expected behavior). Roll
back these messages to be opal_output_verbose() kinds of messages.

This is a separate commit from the commit where the block was removed
from configure.ac because this NEWS bullet will almost certainly not
cherry-pick cleanly to release branches.

We thought there was a silent data corruption issue on POWER 7/BE
systems, so we blocked building on POWER 7/BE systems altogether. We
later figured out that it was just data hangs -- not silent data
corruption. So in hindsight, the configure block probably wasn't
necessary -- but we didn't know it at the time.
Regardless, the hangs have now been fixed, and we're removing the
POWER 7/BE block in configure.

Per 0ab6b201fed, 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 strtoul function returns the pointer to the first non-digit character, which is a '.' in this case. Calling strtoul at that point will always yield a zero - you have to move past it to get the remaining number

the ompio module resets the amode from WRONLY to RDWR in order
to accoomodate data sieving in the two-phase fcoll componet. This
leads however to an error if MPI_MODE_SEQUENTIAL has been requested
by the user, since MODE_SEQUENTIAL is incompatible with MODE_RDWR.
SInce the change to the amode was done after opening the file for
individual file pointers but before opening the file for shared filepointers,
this lead to an error message in the sharedfp component.
Note, that data sieving is never necessary if MODE_SEQUENTIAL is set,
so this should not be a problem for any scenario.

The html man page builder creates a web page for every
man page generated by our releases. We then check all
those pages into the ompi-www repo. Force the build
to skip case-conflicting pages (ie, mpiCC because it
conflicts with mpicc), even if building on Linux, so that
ompi-www continues to be sane when cloned onto MacOS.
