Silence a warning in orted_submit
Protect against a free'd value in an error path when forming oob tcp connections

The problem was observed for direct modex used with recursive doubling
algorithm (used for collective ID calculation prior to d52a2d081e9598a9ac9a50fb4b013a6d2a72375b)
that has pairwise nature and counter-connections are highly likely.
The following scenario was uncovering the issue:
* ranks `x` and `y` want to communicate with each other, `x` < `y`;
* rank `x` initiates the connection and sends the ack;
* rank `y` starts to `connect()` and gets the ack from `x`;
* `y` identifies that it already started connecting and `y` > `x` so it rejects incoming connection.
* `x` sees that his connection was rejected in `mca_oob_tcp_peer_recv_connect_ack()` when trying to
read the message header using `tcp_peer_recv_blocking()` which calls `mca_oob_tcp_peer_close()`
that effectively flushes all the messages in the peer->send_queue.
* `y` send the ack to `x` and the connection is established, however all the messages for the peer
at `x` are vanished (except the front one in peer->send_msg).
This commit introduces a "nack" function that will be used at `y` side to tell `x` that `y` has the
priority and `x`'s connection should be closed. This allows to avoid "guessing" on the unexpectedly
closed connection.

PR open-mpi/ompi#2432 introduced a regression where configure
and build with --disable-dlopn caused build failure owing
to unresolved alps lli symbols in the libopal-pal shared library.
This commit fixes this problem.

there is no need for a configure option as well - so remove the
--enable-orte-static-ports configure option. When decoding the daemon
nidmap, mark new daemons as ALIVE by default - we will discover dead
ones as we go.

* By default, make sure that we are using the short hostnames and not
the fully qualified hostnames when running under LSF.

This commit updates the alps ras component to allow the use of
hyperthreads on compute nodes. In this case we need to use the cpuCnt
value from the node structure instead of numPEs.

Still not completely done as we need a better way of tracking the routed module being used down in the OOB - e.g., when a peer drops connection, we want to remove that route from all conduits that (a) use the OOB and (b) are routed, but we don't want to remove it from an OFI conduit.
add the option to pass an alternate port to plm
for example
node0 port=2222
directs the plm (via the ORTE_NODE_PORT) attribute to use
the non default port 2222 (e.g. ssh -p 2222 node0 ...)
