Address syslog issues on OSX 10.13 with gcc 7.x
gcc 7.[1,2] (at least) fails to correctly parse the OSX 10.13 sys/syslog.h
header. As a results we need to potect syslog support in OPAL, PMIX and
ORTE.

abbe2ffb9f util: Fix graph allocation size
Fix an allocation bug that could occur on non-LP64 platforms.
match_edges_out is an array of integers representing the
edges of the graph (where vertices are ints), with two ints
for every edge.  The previous code allocated enough space
for num_dges * sizeof(int*), which happens to be the same
as num_edges * 2 * sizeof(int) on LP64 platforms, but would
be wrong on all other platforms.

bffcc3bca0 util: move graph solver from usnic to util
Cisco wrote a bipartite graph solver to properly solve
interface pair selection for usNIC.  Using the reachable
framework, the TCP BTL (and possibly the runtime network
code) can use the graph solver to make more optimal pair
selection.  Jeff was happy to have the code more broadly
used, but didn't have time to do the move, hence this
commit.

There are a couple of minor changes to the code compared
to the usNIC version.  Obviously, the functions have
been renamed to match naming convention for their new
home.  Since it's easier to write unit tests for
util/ code, the unit tests have been made first class
tests run at "make check" time.  This last bit required
moving some of the definitions into a new header,
bipartite_graph_internal.h, so that they could be
included in both the library code and the test code.

552216f9ba scripted symbol name change (ompi_ prefix)
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.

d9ad918a14 orte/iof: Address the case when output is a regular file
Regular files are always write-ready, so non-blocking I/O does not
give any benefits for them.
More than that - if libevent is using "epoll" to track fd events,
epoll_ctl will refuse attempt to add an fd pointing to a regular
file descriptor with EPERM.
This fix checks the object referenced by fd and avoids event_add
using event_active instead.

In the original configuration that uncovered this issue "epoll"
was used in libevent, it was triggering the following warning
message:
"[warn] Epoll ADD(1) on fd 0 failed.  Old events were 0; read
change was 1 (add); write change was 0 (none): Operation not
permitted"
And the side effect was accumulation of all output in mpirun
memory and actually writing it only at mpirun exit.

482d84b6e5 fixes for Dave's get/set info code
The expected sequence of events for processing info during object creation
is that if there's an incoming info arg, it is opal_info_dup()ed into the obj
at obj->s_info first. Then interested components register callbacks for
keys they want to know about using opal_infosubscribe_infosubscribe().

Inside info_subscribe_subscribe() the specified callback() is called with
whatever matching k/v is in the object's info, or with the default. The
return string from the callback goes into the new k/v stored in info, and
the input k/v is saved as __IN_<key>/<val>. It's saved the same way
whether the input came from info or whether it was a default. A null return
from the callback indicates an ignored key/val, and no k/v is stored for
it, but an __IN_<key>/<val> is still kept so we still have access to the
original.

At MPI_*_set_info() time, opal_infosubscribe_change_info() is used. That
function calls the registered callbacks for each item in the provided info.
If the callback returns non-null, the info is updated with that k/v, or if
the callback returns null, that key is deleted from info. An __IN_<key>/<val>
is saved either way, and overwrites any previously saved value.

When MPI_*_get_info() is called, opal_info_dup_mpistandard() is used, which
allows relatively easy changes in interpretation of the standard, by looking
at both the <key>/<val> and __IN_<key>/<val> in info. Right now it does
  1. includes system extras, eg k/v defaults not expliclty set by the user
  2. omits ignored keys
  3. shows input values, not callback modifications, eg not the internal values

Currently the callbacks are doing things like
    return some_condition ? "true" : "false"
that is, returning static strings that are not to be freed. If the return
strings start becoming more dynamic in the future I don't see how unallocated
strings could support that, so I'd propose a change for the future that
the callback()s registered with info_subscribe_subscribe() do a strdup on
their return, and we change the callers of callback() to free the strings
it returns (there are only two callers).

Rough outline of the smaller changes spread over the less central files:
  comm.c
    initialize comm->super.s_info to NULL
    copy into comm->super.s_info in comm creation calls that provide info
    OBJ_RELEASE comm->super.s_info at free time
  comm_init.c
    initialize comm->super.s_info to NULL
  file.c
    copy into file->super.s_info if file creation provides info
    OBJ_RELEASE file->super.s_info at free time
  win.c
    copy into win->super.s_info if win creation provides info
    OBJ_RELEASE win->super.s_info at free time

  comm_get_info.c
  file_get_info.c
  win_get_info.c
    change_info() if there's no info attached (shouldn't happen if callbacks
      are registered)
    copy the info for the user

The other category of change is generally addressing compiler warnings where
ompi_info_t and opal_info_t were being used a little too interchangably. An
ompi_info_t* contains an opal_info_t*, at &(ompi_info->super)

Also this commit updates the copyrights.

50aa143ab6 Major structural changes to data types: .super infosubscriber
ompi_communicator_t, ompi_win_t, ompi_file_t all have a super class of type opal_infosubscriber_t instead of a base/super type of opal_object_t (in previous code comm used c_base, but file used super).  It may be a bit bold to say that being a subscriber of MPI_Info is the foundational piece that ties these three things together, but if you object, then I would prefer to turn infosubscriber into a more general name that encompasses other common features rather than create a different super class.  The key here is that we want to be able to pass comm, win and file objects as if they were opal_infosubscriber_t, so that one routine can heandle all 3 types of objects being passed to it.

MPI_INFO_NULL is still an ompi_predefined_info_t type since an MPI_Info is part of ompi but the internal details of the underlying information concept is part of opal.

An ompi_info_t type still exists for exposure to the user, but it is simply a wrapper for the opal object.

Routines such as ompi_info_dup, etc have all been moved to opal_info_dup and related to the opal directory.

Fortran to C translation tables are only used for MPI_Info that is exposed to the application and are therefore part of the ompi_info_t and not the opal_info_t

The data structure changes are primarily in the following files:

    communicator/communicator.h
    ompi/info/info.h
    ompi/win/win.h
    ompi/file/file.h

The following new files were created:

    opal/util/info.h
    opal/util/info.c
    opal/util/info_subscriber.h
    opal/util/info_subscriber.c

This infosubscriber concept is that communicators, files and windows can have subscribers that subscribe to any changes in the info associated with the comm/file/window.  When xxx_set_info is called, the new info is presented to each subscriber who can modify the info in any way they want.  The new value is presented to the next subscriber and so on until all subscribers have had a chance to modify the value.  Therefore, the order of subscribers can make a difference but we hope that there is generally only one subscriber that cares or modifies any given key/value pair.  The final info is then stored and returned by a call to xxx_get_info.

The new model can be seen in the following files:

    ompi/mpi/c/comm_get_info.c
    ompi/mpi/c/comm_set_info.c
    ompi/mpi/c/file_get_info.c
    ompi/mpi/c/file_set_info.c
    ompi/mpi/c/win_get_info.c
    ompi/mpi/c/win_set_info.c

The current subscribers where changed as follows:

    mca/io/ompio/io_ompio_file_open.c
    mca/io/ompio/io_ompio_module.c
    mca/osc/rmda/osc_rdma_component.c (This one actually subscribes to "no_locks")
    mca/osc/sm/osc_sm_component.c (This one actually subscribes to "blocking_fence" and "alloc_shared_contig")

information.

This commit also adds the example of usage of this framework by annotating
rte_init function. The result is not used anywhere for now. It will be

19e5d15491 mpirun --help output revamp
This commit modifies the output from the mpirun --help
command.  The options have been split into groups, to
make the output smaller and more readable.  The groups
are: general, debug, output, input, mapping, ranking,
binding, devel, compatibility, launch, dvm, and
unsupported. There is also a special "full" command
that can be used to get the old behaviour of printing
out all of the options.  Unsupported options may only
be seen with this full output.

This commit also adds a special case for the help
argument.  It makes it possible for the user to
enter 0 or 1 arguments instead of having to always
enter an argument.  This defaults to printing out
the "general" help options so the user can then
see what help arguments there are.

6d98559be9 stacktrace: Add flexibility in stacktrace ouptut
- New MCA option: opal_stacktrace_output
   - Specifies where the stack trace output stream goes.
   - Accepts: none, stdout, stderr, file[:filename]
   - Default filename 'stacktrace'
     - Filename will be `stacktrace.PID`, or if VPID is available,
       then the filename will be `stacktrace.VPID.PID`
 - Update util/stacktrace to allow for different output avenues
   including files. Previously this was hardcoded to 'stderr'.
 - Since opal_backtrace_print needs to be signal safe, passing it a
   FILE object that actually represents a file stream is difficult. This
   is because we cannot open the file in the signal handler using
   `fopen` (not safe), but have to use `open` (safe). Additionally, we
   cannot use `fdopen` to convert the `int fd` to a `FILE *fh` since it
   is also not signal safe.
   - I did not want to break the backtrace.h API so I introduced a new
     rule (documented in `backtrace.c`) that if the `FILE *file`
     argument is `NULL` then look for the `opal_stacktrace_output_fileno`
     variable to tell you which file descriptor to use for output.

dcd9801f7c orte/iof: Add orte_map_stddiag_to_stdout option
* Similar to `orte_map_stddiag_to_stderr` except it redirects `stddiag`
   to `stdout` instead of `stderr`.
 * Add protection so that the user canot supply both:
   - `orte_map_stddiag_to_stderr`
   - `orte_map_stddiag_to_stdout`

b257c32d2c Cleanup the os_dirpath logic so it doesn't error out if the directory actually gets created (regardless of what mkdir returns), and pretty-prints the error if it does error out.

9eab9a1ed3 Remove stale global variables
Revamp the event notification integration to rely on the PMIx event chaining and remove the duplicate chaining in OPAL. This ensures we get system-level events that target non-default handlers.

Restore the hostname entries for MPI-level error messages, but provide an MCA param (orte_hostname_cutoff) to remove them for large clusters where the memory footprint is problematic. Set the default at 1000 nodes in the job (not the allocation).

Begin first cut at memory profiler

8fd1c3f0df opal/util: handle a race condition in opal_os_dirpath_destroy
An file might have been destroyed by an other task between
readdir() and stat(), so simply ignore stat() failure.

That typically occurs when one task is removing the job_session_dir
and an other task is still removing its proc_session_dir.
