This commit also modifies _OMPI_CHECK_HEADER to use AC_CHECK_HEADERS instead
of AC_CHECK_HEADER. This allows components to check for multiple headers
instead of just one. The new semantics of the header check in OMPI_CHECK_PACKAGE
are to return success if at least one of the specified headers exists. The new
semantics will not break current usage.

standard). If a compiler allows this behavior, build the mpi_f08
wrapper. For example, ifort allows it, but Pathscale/EKOPath 5.0 is
stricter in its Fortran compliance and disallows it.
This test is temporary; the real fix is to make OMPI adhere to Fortran
properly (i.e., see #4157). Once we fix#4157, this test should be
removed. The main reason for committing this test is to put it into
v1.7.4 so that we can release, but with the intent to remove it by
1.7.5 (or 1.8.x at the latest!).

Per discussion on the devel list starting here:
http://www.open-mpi.org/community/lists/devel/2014/01/13799.php we
need a new litmus test to disqualify older Fortran compilers (e.g.,
Pathscale 4.0.12) that *seem* to support all the Right Things, but a)
do not support BIND(C, name="super_long_name") or b) run into an
internal error when compiling our mpi_f08 module.
Testing for b) is sketchy at best. But OMPI has some BIND(C) names
that are >32 characters, and the same compilers that exhibit b) also
seem to not support BIND(C) names that are >32 characters (i.e., a)).
Hence, the following BIND(C) test checks to ensure that BIND(C,
name="foo") works, where "foo" is actually a name >32 characters.

Add a configure test to see if the Fortran compiler supports the
PROTECTED keyword. If it does, use in mpi-f08-types.F90 (via a macro
defined in configure-fortran-output-bottom.h).
This is needed to support the PGI 9 Fortran compiler, which does not
support the PROTECTED keyword.
Note that regardless of whether we want to support the PGI 9 Fortran
compiler + mpi_f08, we need to correctly detect whether PROTECTED
works or not, and then use that determination as a criteria for
building the mpi_f08 module. Previously, mpi-f08-types.F90 used
PROTECTED unconditionally, and we didn't test for it in configure. So
if a compiler (e.g., PGI 9) supported everything else but didn't
support PROTECTED, it would try to compile the mpi_f08 stuff and choke
on the use of PROTECTED.

This configure option was only relevant when we were generating TKR
"use mpi" interfaces for MPI subroutines with choice buffers. Now
that we aren't, the only interface that needs to accept a choice
buffer is MPI_SIZEOF (which we have to provide).
And since there's now only several dozen interfaces in the "mpi" TKR
module, there's no reason to not generate ''all'' possible array rank
values (when there were thousands of interfaces, generating 4-vs-7
array ranks per interface per type was a big deal). The default used
to be 4; now we can just hard-code it to 7, the max possible value for
Fortran 2003 (I think the max was raised ?to 11? in F2008, but let's
not go there for now).

* ISO_C_BINDING
* SUBROUTINE ... BIND(C)
* TYPE, BIND(C)
* TYPE(foo), BIND(C, name="bar")
If the compiler supports all of these, then declare that we support
BIND(C), and the rest of the mpi_f08 checks can continue. If we miss
any one of those, don't bother continuing -- we won't build the
mpi_f08 module.
Also push the results of all of these tests down to ompi_info so that
they can be reported easily (e.g., "Hey, why doesn't my OMPI
installation have the mpi_f08 module?").

oshmem_info_register_framework_params()
oshmem_info_close_components()
oshmem_info_show_oshmem_version()
These functions call ompi_info_support related interfaces as long as
Oshmem supports Open MPI/SHMEM combination.
Now orte_info/ompi_info/oshmem_info have identical implementation approach.
Possible improvement:
OSHMEM processing of --config option is the same as OMPI`s (code is duplicated).
Probably list of info_support interfaces can be extended by xxx_info_do_config().

*** THIS RFC INCLUDES A MINOR CHANGE TO THE MPI-RTE INTERFACE ***
Note: during the course of this work, it was necessary to completely separate the MPI and RTE progress engines. There were multiple places in the MPI layer where ORTE_WAIT_FOR_COMPLETION was being used. A new OMPI_WAIT_FOR_COMPLETION macro was created (defined in ompi/mca/rte/rte.h) that simply cycles across opal_progress until the provided flag becomes false. Places where the MPI layer blocked waiting for RTE to complete an event have been modified to use this macro.
***************************************************************************************
I am reissuing this RFC because of the time that has passed since its original release. Since its initial release and review, I have debugged it further to ensure it fully supports tests like loop_spawn. It therefore seems ready for merge back to the trunk. Given its prior review, I have set the timeout for one week.

WHAT: Rewrite of ORTE OOB
WHY: Support asynchronous progress and a host of other features
WHEN: Wed, August 21
SYNOPSIS:
The current OOB has served us well, but a number of limitations have been identified over the years. Specifically:
* it is only progressed when called via opal_progress, which can lead to hangs or recursive calls into libevent (which is not supported by that code)
* we've had issues when multiple NICs are available as the code doesn't "shift" messages between transports - thus, all nodes had to be available via the same TCP interface.
* the OOB "unloads" incoming opal_buffer_t objects during the transmission, thus preventing use of OBJ_RETAIN in the code when repeatedly sending the same message to multiple recipients
* there is no failover mechanism across NICs - if the selected NIC (or its attached switch) fails, we are forced to abort
* only one transport (i.e., component) can be "active"
The revised OOB resolves these problems:
* async progress is used for all application processes, with the progress thread blocking in the event library
* each available TCP NIC is supported by its own TCP module. The ability to asynchronously progress each module independently is provided, but not enabled by default (a runtime MCA parameter turns it "on")
* multi-address TCP NICs (e.g., a NIC with both an IPv4 and IPv6 address, or with virtual interfaces) are supported - reachability is determined by comparing the contact info for a peer against all addresses within the range covered by the address/mask pairs for the NIC.
* a message that arrives on one TCP NIC is automatically shifted to whatever NIC that is connected to the next "hop" if that peer cannot be reached by the incoming NIC. If no TCP module will reach the peer, then the OOB attempts to send the message via all other available components - if none can reach the peer, then an "error" is reported back to the RML, which then calls the errmgr for instructions.
* opal_buffer_t now conforms to standard object rules re OBJ_RETAIN as we no longer "unload" the incoming object
* NIC failure is reported to the TCP component, which then tries to resend the message across any other available TCP NIC. If that doesn't work, then the message is given back to the OOB base to try using other components. If all that fails, then the error is reported to the RML, which reports to the errmgr for instructions
* obviously from the above, multiple OOB components (e.g., TCP and UD) can be active in parallel
* the matching code has been moved to the RML (and out of the OOB/TCP component) so it is independent of transport
* routing is done by the individual OOB modules (as opposed to the RML). Thus, both routed and non-routed transports can simultaneously be active
* all blocking send/recv APIs have been removed. Everything operates asynchronously.
KNOWN LIMITATIONS:
* although provision is made for component failover as described above, the code for doing so has not been fully implemented yet. At the moment, if all connections for a given peer fail, the errmgr is notified of a "lost connection", which by default results in termination of the job if it was a lifeline
* the IPv6 code is present and compiles, but is not complete. Since the current IPv6 support in the OOB doesn't work anyway, I don't consider this a blocker
* routing is performed at the individual module level, yet the active routed component is selected on a global basis. We probably should update that to reflect that different transports may need/choose to route in different ways
* obviously, not every error path has been tested nor necessarily covered
* determining abnormal termination is more challenging than in the old code as we now potentially have multiple ways of connecting to a process. Ideally, we would declare "connection failed" when *all* transports can no longer reach the process, but that requires some additional (possibly complex) code. For now, the code replicates the old behavior only somewhat modified - i.e., if a module sees its connection fail, it checks to see if it is a lifeline. If so, it notifies the errmgr that the lifeline is lost - otherwise, it notifies the errmgr that a non-lifeline connection was lost.
* reachability is determined solely on the basis of a shared subnet address/mask - more sophisticated algorithms (e.g., the one used in the tcp btl) are required to handle routing via gateways
* the RML needs to assign sequence numbers to each message on a per-peer basis. The receiving RML will then deliver messages in order, thus preventing out-of-order messaging in the case where messages travel across different transports or a message needs to be redirected/resent due to failure of a NIC
