* Remove the ptmalloc memory component; replace it with a new "linux"
memory component.
* The linux memory component will conditionally compile in support
for ummunotify. At run-time, if it has ummunotify support and
finds run-time support for ummunotify (i.e., /dev/ummunotify), it
uses it. If not, it tries to use ptmalloc via the glibc memory
hooks.
* Add some more API functions to the memory framework to accomodate
the ummunotify model (i.e., poll to see if memory has "changed").
* Add appropriate calls in the rcache to the new memory APIs to see
if memory has changed, and to react accordingly.
* Add a few comments in the openib BTL to indicate why we don't need
to notify the OPAL memory framework about specific instances of
registered memory.
* Add dummy API calls in the solaris malloc component (since it
doesn't have polling/"did memory change" support).

btl_openib_ip.*. The routines in these files are not specific to
iwarp -- they are specific to IP interfaces used with IBV devices
(even IB or IBoE/RoCEE/whatever devices).

point, the event engine has been shut down until btl finalization is
done, so opal_progress in the wait loop is not an option - we have
to drain from inside the btl.
Clean up the looping structure for the finalize routine

(now works on both big and little endian machines)
* Be a little more flexible when looking for active devices in
btl_openib_component.c
* Add device name and port number to lots of verbose and help
messages
* Add a bunch of verbose messages to give insight into what is
occurring during all the CPC wireups

- Delete unnecessary header files using
contrib/check_unnecessary_headers.sh after applying
patches, that include headers, being "lost" due to
inclusion in one of the now deleted headers...
In total 817 files are touched.
In ompi/mpi/c/ header files are moved up into the actual c-file,
where necessary (these are the only additional #include),
otherwise it is only deletions of #include (apart from the above
additions required due to notifier...)
- To get different MCAs (OpenIB, TM, ALPS), an earlier version was
successfully compiled (yesterday) on:
Linux locally using intel-11, gcc-4.3.2 and gcc-SVN + warnings enabled
Smoky cluster (x86-64 running Linux) using PGI-8.0.2 + warnings enabled
Lens cluster (x86-64 running Linux) using Pathscale-3.2 + warnings enabled

anyhow -- if oob functionality is neededm then orte/mca/oob/oob.h
Nevertheless compiles fine with -Wimplicit-function-declaration
This commit was SVN r20641.
Often, orte/util/show_help.h is included, although no functionality
is required -- instead, most often opal_output.h, or
orte/mca/rml/rml_types.h
Please see orte_show_help_replacement.sh commited next.
- Local compilation (Linux/x86_64) w/ -Wimplicit-function-declaration
actually showed two *missing* #include "orte/util/show_help.h"
in orte/mca/odls/base/odls_base_default_fns.c and
in orte/tools/orte-top/orte-top.c
Manually added these.

btl_openib_connect_rdmacm_reject_causes_connect_error (yes, it's
still long -- on purpose :-) )
* Add INI file parameter rdmacm_reject_causes_connect_error
* Now only treat CONNECT_ERROR events as a REJECT if:
* It's on a connection where we were expecting a REJECT, ''and''
* The MCA parameter is true ''or'' the INI parameter for this
device is true
* Set the INI parameter for true for the NE020

properly at all. NetEffect's current driver (OFED 1.4.0) will return
a CONNECT_ERROR event to the initiator rather than the REJECTED event.
Doh! Additionally -- unfortunately -- NetEffect's vendor_id and
vendor_part_id are reported as 0 in OFED 1.4.0, so we can't
automatically detect these cards and work around the problem. So all
we can do is add a new MCA parameter
(btl_openib_connect_rdmacm_ignore_connect_errors -- yes, it's long on
purpose ;-) ) that says that if we get a CONNECT_ERROR, bascially
treat it exactly as a REJECT for the WRONG_DIRECTION reason (which is
a "good" reject). This allows OMPI to function with NetEffect/Intel
cards on OFED 1.4.0.
Note that NetEffect has been bought by Intel; I'm waiting for
information from them to update the ini file for their new OUI/PCI
ID's and/or new vendor_part_id values.

determining which IP address to use when transmitting data. Also it adds logic
to prevent usage of more than one of the btl_openib_if_include,
btl_openib_if_exclude, btl_openib_ipaddr_include, or btl_openib_ipaddr_exclude
MCA parameters.
This should complete the code modifications needed for ticket 1665.

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

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)

"!OpenFabrics" / neutral (i.e., refer to IB and/or iWARP).
* Mostly just type, variable/field, and funcion name changes, such as
s/hca/device/g, etc.
* Changed the INI file for the hardware-specific parameters to be
mca-btl-openib-device-params.ini.
* Updated a lot of help messages in the help-*.txt files, not just to
update it to be !OpenFabrics/neutral language, but also for some
consistency of tone, indenting, etc.
* Deprecated a bunch of MCA params in favor of language-neutral new
ones:
* btl_openib_warn_no_hca_params_found (s/hca/device/)
* btl_openib_hca_param_files
* btl_openib_ib_cq_size (s/_ib_/_of_/)
* btl_openib_ib_max_inline_data
* btl_openib_ib_psn

The rdmacm event handler has no way of reporting fatal errors to the upper
layers. By calling mca_btl_openib_endpoint_invoke_error in the rdmacm event
handler for the errors encountered, these errors can now be handled
appropriately.
Closes out Ticket #1283

If IBCM was explicitly specified with exclude/include parameter,
OpenIB BTL will enable verbose report for "/dev/infiniband/ucm" error,
other way the error will not be reported.

first to the trunk. So, here is the trunk checkin:
The call to orte_show_help() to notify truncation of the max_inline value
was missing the want_error_header boolean, which eventually results in
a SEGV. This change corrects the call with the bool set to true.

* Move the passive side QP move to RTS to before we send the reply
(vs. sending it after we get the RTU). A lengthy comment explains
the need for this.
* Add some timers to the code for analyzing where time is spent.
* Clarify a few error messages.
* Currently have a loop around ib_cm_listen() because sometimes it
fails for seeminly no reason. Have pending e-mails in to Sean
Hefty to see if we can figure out why this is happening. Note that
the more MPI processes you add, the more likely this error is to
occur (e.g., ran 720 processes and it happens at least 50% of the
time). This makes IBCM somewhat unattractive for general use;
hopefully we can get a fix...

XOOB, and IBCM now all invoke the btl error handler properly if
there's an error during wireup. RDMACM still needs to be done.
