when running an MPI job spanning a node that has two TCP NICs and a
node that has one TCP NIC. Previously, for the 2 NIC/module process,
we would return the first peer IP address if we couldn't find a subnet
match with any of the peer's published IP addresses -- this was to
support running OMPI across subnet boundaries. Changed the behavior
to only do that behavior if the IP address we're trying to match is
public (i.e., not 10.x.y.z, 192.168.x.y, or 172.16.x.y) *and* any of
the remote peer's addresses are public (working on the assumption that
if we both have public addresses, they're routable to each other).
This definitely will not work in all scenarios, such as when we go to
WAN kinds of executions, and will need to be revisited at that time.

* fix a silly bug where we weren't adding a long accumulate message to
the pending long messages list, so we hung if a long accumulate
occurred. Still having some memory issues on one of the tests I'm
running - need to move over to Linux and Valgrind after some sleep.

what is going on
* Fix a dumb error where if a lock was released and another was pending, I
would send a lock *request* to the queued process, rather than giving
him the lock and sending him a lock *ack*. Turns out requests and
acks are different things :)

- Explained <program> and made a consistancy change in the Quick Start section.
- Change references to 'app schema' to Open MPI 'app context'
- Audit the command line arguments for --foo, -foo stuff.

MPI informations stored in args (the MPI_COMBINER stuff). This function
print only one level of information but it expand the name of the
datatype if the data is a predefined one.

and cwd update functionality. For bproc, we *do* need to change
directories while checking the cwd because argv[0] may be expressed as
a relative path, and therefore needs to be checked from the cwd
expressed in the app context.

This needs to be gone over a few more times before it is allowed to see
daylight, but has come a long way. Some sections may be off more than a little,
but the general idea is there.
Need to audit to make sure we don't call the ORTE VHNP's daemons :)

Finished adding and pruning all the the Options.
Cleaned up a bunch of man syntax, so it should be 'more' readable (making the
assumption that man source is ever readable :p).
I am moving on to the "description" and "see also" sections next.

argv[0] and the cwd on the target node (i.e., the node where the
executable will be running in all systems except BProc, where the
searches are run on the node where orterun is invoked).
- fork pls now does cwd and argv[0] search in orted
- bproc pls does cwd and argv[0] search in orterun
- cwd behavior slightly different:
- if user specifies a -wdir to orterun, we chdir() to there; if we
can't for some reason, abort
- if user does not specify a -wdir, try to chdir() to the dir where
orterun was invoked. If we can't for some reason (e.g., it
doesn't exist on the target node), then try to chdir($HOME). If
we can't do that, then just live with whatever default directory
we were put in.

Note, the checksums are not enabled currently, setting to zero as the
convertor is not ready for checksums yet.
Also, we can't call unpack/pack on convertor with 0 bytes, otherwise it
crashes.
