This patch reshape the way we deal with topologies completely. Where
our topologies were mainly storage components (they were not capable
of creating the new communicator), the new version is built around a
[possibly] common representation (in mca/topo/topo.h), but the functions
to attach and retrieve the topological information are specific to each
component. As a result the ompi_create_cart and ompi_create_graph functions
become useless and have been removed.
In addition to adding the internal infrastructure to manage the topology
information, it updates the MPI interface, and the debuggers support and
provides all Fortran interfaces.
This commit was SVN r28687.
To resolve this situation, add the ability to specify a backend topology file that mpirun shall use for its mapping operations. Create a new "set_topology" function in opal hwloc to support it.

- orte_debugger_init_after_spawn was not being called for debuggers that
use the MPIR_attach_fifo to co-locate debugger daemons.
- MPIR_Breakpoint was not getting called if a debugger reattached. Add
a job state (ORTE_JOB_STATE_DEBUGGER_DETACH) to reset mpir_breakpoint_fired
to false when a debugger detaches to ensure MPIR_Breakpoint is called if
another debugger attaches. Tested with STAT 2.0/launchmon 1.0.

There is no good way to recover from this scenario, and from past experience, using the user's name in the session directory (as opposed to the uid) is very helpful when things go wrong. So print a help message when this happens (it is extremely rare, but has happened at least once now) and return an error.

Chose the crc32 function present in opal/util/crc.c as the hash function. The
performance should be sufficient for most cases. If not we can always change
the function again.

As per discussion in the June 2013 developer meeting these
flags will be used by the PML in the future to request
asynchronous progress on an operation. The naming was chosen
to reflect that a BTL supports this mode (MCA_BTL_FLAG_SIGNALED)
and that a descriptor should "signal" the remote side to wake
up and progress the message (MCA_BTL_DES_FLAG_SIGNAL).
Future commits will update OB1 to take advantage of this
feature when performing the RDMA get or RDMA rendezvous
protocols.

commit is the trunk version of what is needed for #3626.
Add the "ignore_device" field to the INI file. This allows us to
specifically list devices that should be ignored by the openib BTL
(such as the Intel Phi, at least as of May 2013 -- see #3626).
Also add the Intel Phi to the ini file, and set its ignore_device=1.
Finally, add the concept of counting intentionally ignored verbs
devices. Devices are ignored for one of two reasons:
* If the number of allowed ports on that device is 0 (i.e., if
if_include/if_exclude was set such that we're intentionally
ignoring this device).
* If the INI ignore_device field for this device is set to 1.
Once we have the count of devices that were intentionally ignored,
only show the "Hey, there's verbs devices that you're not using!"
show_help message if there are devices that were ''unintentionally''
ignored.
