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.

determing of the IP subnet. The netmask was being used improperly when
determining which subnet each connection is on. Part two is the ability to
include/exclude specific subnets.
This patch fixes ticket #1665
This commit was SVN r20016.
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)

ompi_info will crash due to a reference to a unalloced struct. Add a check for
this struct to prevent this crash.

If rdmacm cpc is disabled and an iwarp device is forced to be used, then
mca_btl_openib_get_iwarp_subnet_id will attempt to reference an uninitalized
list. Modify the code to check for the uninitalized list and return zero.
Also, fix a memory leak caused by not freeing alloced addresses structs during
shutdown.

* Ensure _iwarp.h is always included, or you'll get warnings on
platforms that don't have the RDMACM
* Add skeleton for function descriptions in comments in iwarp.h

opal_ifnext() return -1 upon completion); don't check it against
opal_ifcount() -- the interface indexes aren't necessarily related to
how many interfaces were found.
This commit was SVN r18476.
The iWARP subnet ID determination should not be in the RDMACM cpc, as
it was in the preversion, as this violates the cpc abstract that is
present throughout the code. Also, this patch uses the opal_list_t
data struct instead of using its own linked lists.
This attempt includes *iwarp.c and *iwarp.h
