structures in the system. Instead of using memcmp, use the ns function.
This won't cause a problem as long as all three elements of the name are
ints, but if they have different sizes, alignment and padding rules
can cause memcmp() to compare padding space, which rarely holds a sane
value.

* Move ipv6comat.h code into opal_config_bottom.h and change into some
more intelligent testing of structures
* Change opal's if interface to use sockaddr instead of sockaddr_storage,
as the RFCs suggest we do
* Move the networking code in opal that isn't directly related to if
detection into net.h
* Add quicky function to get the port out of either a sockaddr_in
or sockaddr_in6, saving a bunch of code in the oob.
* Update TCP oob and btl with new interface

during the IPv6 patch. The most important is the multi BTL support. There
was a quite interesting bug. Instead of setting up the multiple connections
over different physical devices, based on the time when these connections
were created most of the time they were all using the same physical network.
Which, of course, was not the intended goal, as we top at the maximum
bandwidth available over one device instead of gathering all available
bandwidth from all devices.
Second, the IPv6 RFC suggest to use sockaddr_storage as a holder for the
IP information, but use a sockaddr* when we pass it to functions. This is
only partially corrected by this patch.
Some other minor cleanups.

- make opal_sockaddr2str() take a sockaddr_storage instead of a sockaddr_in6
so that it works for IPv4 and IPv6 addresses, and remove a whole bunch
of #ifs in the OOOB code.
- Fix a compiler warning in the TCP BTL due to run-time determined
array size by making it a dynamicly allocated array.
- Fix the unpacking code of IPv4 addresses when using IPv6 support, so
that the address is in the correct location (instead of in an IPv6
structure, use an IPv4 structure). Refs trac:1005.

The following Trac tickets were found above:

latency is high and the network relatively fast. This will allow for more kernel
level buffering, which allow overlap between system calls and communications.
Somehow, even on fast clusters there is an improvement (non significant).
This patch create multiple modules for the same device, which in turn will
create multiple sockets between the peers. By default the number of BTL by
device is set to 1, so there is no fundamental difference with the current
version. Change the value of btl_tcp_links to enable multiple links between
peers.

- consistent error message when something fails (via BTL_ERROR macro)
- decrease the number of jumps.
- cleanup some parts of the code.

because they are in ORTE, not OMPI. Also, remove the ORTE_PROCESS_NAME macros
in iof base as they are duplicates of the ones that were in ns_types, which
meant that bad things happened if you changed what an orte_process_name_t
looked like.

Accordingly, there are new APIs to the name service to support the ability to get a job's parent, root, immediate children, and all its descendants. In addition, the terminate_job, terminate_orted, and signal_job APIs for the PLS have been modified to accept attributes that define the extent of their actions. For example, doing a "terminate_job" with an attribute of ORTE_NS_INCLUDE_DESCENDANTS will terminate the given jobid AND all jobs that descended from it.
I have tested this capability on a MacBook under rsh, Odin under SLURM, and LANL's Flash (bproc). It worked successfully on non-MPI jobs (both simple and including a spawn), and MPI jobs (again, both simple and with a spawn).

Instead of figuring out which free list the fragment belongs to based on size
we simply store a pointer to the list which it belongs in the fragment.
This was reviewed by Brian and should hit all the branches.

- moved hton64 and ntoh64 from the bunch of places it had been copied
into one header file
- properly set and use the btl_tcp's nbo option to put things in
network byte order on the wire if both sides don't have the same
endianness
- Put the OB1 PML's headers (with a couple exceptions I need to discuss
with Tim) in network byte order on the wire if both sides don't have
the same endianness
- since it was needed for the TCP BTL, move the orte_process_name_t
HTON and NTOH macros from the TCP OOB to ns_types.h

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

empty for non threaded builds, but somehow just by moving the code a
little bit around and removing 2 call to lock/unlock the latency for TCP
went down by 2 micro-seconds ...

number of recv system call by caching the data. Each endpoint has a buffer
(the size is an MCA parameter) that can be use as a cache. Before each receive
operation this buffer is added at the end of the iovec list. All data that are
not expected by the fragment will go in this cache. If the cache contain data
all subsequent receive will just memcpy the data into the BTL buffers.
The only drawback is that we will spin around the receive_handle until all the
cached data is readed by the PML layer. This limitation come from the fact that
the event library is unable to call us if there is no events on the socket.
Therefore we are unable to keep the data in the cache until the next loop
into the progress engine.
