If you use --prefix and then "-x LD_LIBRARY_PATH", the rsh pls would
take great pains to ensure that PATH and LD_LIBRARY_PATH were setup
correctly on the local and remote nodes, but then the fork pls would
blitely overwrite LD_LIBRARY_PATH with what the user exported (i.e.,
most likely without our prefix). This patch takes care of that -- the
fork pls examines the incoming environment, and if it sees PATH or
LD_LIBRARY_PATH, it re-prefixes those variables.

it is possible that if the receive has been arrived the callback will
be called before recv_buffer_nb() returns. This causes deadlock
as we try to acquire the lock, but already hold it.
This was causing orterun and orteds to stall in certian situations.
Became evident when stress testing dynamics with remote nodes.

- Fix bug identified by users: --prefix may also apply on the local
node; we need to prefix the PATH and LD_LIBRARY_PATH environment
variables before invoking execve()

some orted's to stall on locks in the MPI Dynamics cases. Since it
is not essentual that we call these functions, they can so away.
Unlock the peer lock when aborting. This causes a potential deadlock
in do_waitall [see comment in code]. This was causing orteds to
deadlock at times when the seed had terminated. With proper interleaving
and timing the orted was deadlocking. This seems to have fixed this in
my stress testing with MPI 2 Dynamics.

The NS replica should give out tags that are over ORTE_RML_TAG_DYNAMIC
or it will overlap with other outstanding tags. This overlap was killing
MPI_Comm_spawn when a program tried to use it multiple times (> 3).
With this fix MPI_Comm_spawn is behaving properly.
A program can call it many times in a row with out problem.

Have the ras_base_schedule_policy MCA parameter working once again. before it
would only do slot based allocation, even if the MCA parameter was set properly.
Currently you can specify to orterun a node allocation by either:
-mca ras_base_schedule_policy node
-bynode
and slot allocation (which is the default) by:
-mca ras_base_schedule_policy slot
-byslot

with the mutex locked and as this function will call oob_send which will call the lookup again
... we will deadlock as the mutex is already lock. The solution is to release the mutex before
going into the subscription. Then of course the logic to remote the item when something went
wrong with the subscrition is a little bit more complex.

add an event, it can call the spawn function directly. This will avoid it standing on the condition who
will never get released.

This fixes one of the race conditions in orterun is sent a kill signal.
Before it would sometimes spin in the OOB waiting for a message to complete
to a peer that was no longer around. Stalling at this level prevented orterun
from noticing that it had received a kill signal.

- Sample in each of the three projects of how to link againt the
relevant libraries so that when components are loaded into a parent
process' space, we don't rely on the libopal/liborte/libmpi symbols
being in the parent's public symbol namespace -- instead,
dynamically link to the relevant libraries, allowing the dynamic
linker to pull those libraries in at run-time, if needed

However we do want to do a bit of cleanup on the node before we exit,
specificly clean out the session directory. I also had a couple of the
subsystems that don't depend upon peers (which is key) clean up as well.

caller to specify a subset of the state variables that it can can subscribe to.
This is specified with one of three special flags defined in rmgr/rmgr_types.h
This is useful when we only care about a subset of the state changes, such as
in orted which only needs to know when a job has terminated or aborted.

The following formats are parsed:

user@fqdn
IPv4 or fqdn [username|user-name|user_name]=user
- Try a better error-detection when parsing (recognize wrong
IPs, fqdns...)
