1. completely and cleanly separates responsibilities between the HNP, orted, and tool components.
2. removes all wireup messaging during launch and shutdown.
3. maintains flow control for stdin to avoid large-scale consumption of memory by orteds when large input files are forwarded. This is done using an xon/xoff protocol.
4. enables specification of stdin recipients on the mpirun cmd line. Allowed options include rank, "all", or "none". Default is rank 0.
5. creates a new MPI_Info key "ompi_stdin_target" that supports the above options for child jobs. Default is "none".
6. adds a new tool "orte-iof" that can connect to a running mpirun and display the output. Cmd line options allow selection of any combination of stdout, stderr, and stddiag. Default is stdout.
7. adds a new mpirun and orte-iof cmd line option "tag-output" that will tag each line of output with process name and stream ident. For example, "[1,0]<stdout>this is output"
This is not intended for the 1.3 release as it is a major change requiring considerable soak time.

Valgrind header files if they weren't already in the compiler's
default header file search path. This commit fixes that typo and adds
a little more infrastructure (via an AC_SUBST) to pass in the relevant
CPPFLAGS to the build system for the valgrind memchecker component.

There is still a problem with OpenIB and threads (external to C/R functionality). It has been reported in Ticket #1539
Additionally:
* Fix a file cleanup bug in CRS Base.
* Fix a possible deadlock in the TCP ft_event function
* Add a mca_base_param_deregister() function to MCA base
* Add whole process checkpoint timers
* Add support for BTL: OpenIB, MX, Shared Memory
* Add support Mpool: rdma, sm
* Sundry bounds checking an cleanup in some scattered functions

The segv was caused by the fact that we don't really know which daemon failed to start (at least, in most cases), so we didn't set a pointer to the aborted proc object. All we really wanted, though, was to ensure that mpirun returned a non-zero exit status, so the fix was to simply return the default error status.

I run IMB exchange on two QS22 machines with r19674 and it got stucked after 256 or 512 bytes every time.
After applying r19717 the test passed, so I guess this is a essential patch.

- Unify the Windows and the others way of handling callbacks. Thanks to George.
- This will let Windows use the same callbacks as Linux does, which works also.

unconditionally, which can result in a flood of messages to the user
if all MPI processes invoke abort. Additionally, some users were
confused because they saw the MPI_ABORT opal_output() messages from
''some'' MPI processes, but not ''all'' of them (despite the fact that
every MPI process supposedly invoked MPI_ABORT). The reason is that
calling MPI_ABORT triggers ORTE to kill all MPI processes, so it's a
race condition as to whether a) all MPI processes actually invoke
MPI_ABORT, and/or b) whether every process is able to opal_output()
before they are killed.
This commit does two simple things:
* Now use orte_show_help() for the MPI_ABORT message, so they are
aggregated.
* Add a note in the message that calling MPI_ABORT kills all
processes, so you might not see all output, yadda yadda yadda.

We still do an interreduce but it is now followed by an intrascatterv.
This fixes trac:1554.
This commit was SVN r19723.
The following Trac tickets were found above:
Ticket 1554 --> https://svn.open-mpi.org/trac/ompi/ticket/1554
following names are all new for v1.3, and therefore haven't been
officially released yet:
* btl_openib_of_cq_size
* btl_openib_of_max_inline_data
* btl_openib_of_pkey
* btl_openib_of_psn
* btl_openib_of_mtu
The "_of_" (for OpenFabrics) in there is redundant. It used to be
"_ib_", indicating that these values are pretty much passed directly
to the verbs stack. But I think the "openib" in the name implies this
already; having "_of_" in there just seems redundant, makes the name
longer, and seems redundant. It's also redundant.
So I took those "_of_"'s out of the MCA names. The old (v1.2) names
are still valid (but deprecated), such ash btl_openib_ib_cq_size.
This commit was SVN r19718.
* Change name: mca_btl_openib_of_pkey_value -> mca_btl_openib_of_pkey
(since now there's no index, the "_value" suffix is somewhat
superfluous)
* Put in a better help message for the _pkey MCA param (to agree with
the new help message in v1.2.8)

Fix a finalize bug with the C/R thread. There is a race in the way we were finalizing the C/R thread such that, given a particular interleaving of threads, the pthread_join would stall because the C/R thread was never released properly.
Found in MTT regression testing on Odin.
All and all if you were not compiling with FT & threading support you would never see this problem.
This commit was SVN r19708.
Commit from a long-standing Mercurial tree that ended up incorporating a lot of things:
* A few fixes for CPC interface changes in all the CPCs
* Attempts (but not yet finished) to fix shutdown problems in the IB CM CPC
* #1319: add CTS support (i.e., initiator guarantees to send first message; automatically activated for iWARP over the RDMA CM CPC)
* Some variable and function renamings to make this be generic (e.g., alloc_credit_frag became alloc_control_frag)
* CPCs no longer post receive buffers; they only post a single receive buffer for the CTS if they use CTS. Instead, the main BTL now posts the main sets of receive buffers.
* CPCs allocate a CTS buffer only if they're about to make a connection
* RDMA CM improvements:
* Use threaded mode openib fd monitoring to wait for for RDMA CM events
* Synchronize endpoint finalization and disconnection between main thread and service thread to avoid/fix some race conditions
* Converted several structs to be OBJs so that we can use reference counting to know when to invoke destructors
* Make some new OBJ's have opal_list_item_t's as their base, thereby eliminating the need for the local list_item_t type
* Renamed many variables to be internally consistent
* Centralize the decision in an inline function as to whether this process or the remote process is supposed to be the initiator
* Add oodles of OPAL_OUTPUT statements for debugging (hard-wired to output stream -1; to be activated by developers if they want/need them)
* Use rdma_create_qp() instead of ibv_create_qp()
* openib fd monitoring improvements:
* Renamed a bunch of functions and variables to be a little more obvious as to their true function
* Use pipes to communicate between main thread and service thread
* Add ability for main thread to invoke a function back on the service thread
* Ensure to set initiator_depth and responder_resources properly, but putting max_qp_rd_ataom and ma_qp_init_rd_atom in the modex (see rdma_connect(3))
* Ensure to set the source IP address in rdma_resolve() to ensure that we select the correct OpenFabrics source port
* Make new MCA param: openib_btl_connect_rdmacm_resolve_timeout
* Other improvements:
* btl_openib_device_type MCA param: can be "iw" or "ib" or "all" (or "infiniband" or "iwarp")
* Somewhat improved error handling
* Bunches of spelling fixes in comments, VERBOSE, and OUTPUT statements
* Oodles of little coding style fixes
* Changed shutdown ordering of btl; the device is now an OBJ with ref counting for destruction
* Added some more show_help error messages
* Change configury to only build IBCM / RDMACM if we have threads (because we need a progress thread)
