Fix a potential problem with RM-provided nodenames not matching returns from gethostname - ensure that the HNP's nodename gets DNS-resolved when comparing against RM-provided hostnames. Note that this may be an issue for RM-based clusters that don't have local DNS resolution, but hopefully that is more indicative of a poorly configured system.

Contains:
* Primarily a fix for a user reported problem where a cached file descriptor is causing a SIGPIPE on restart.
* Cleanup some small memory leaks from using mca_base_param_env_var() - Thanks Jeff
* Cleanup ORTE FT tool compilation in non-FT builds - Thanks Tim P.
* Cleanup mpi interface with missplaced {{{OPAL_CR_ENTER_LIBRARY}}} - Thanks Terry
* Some other sundry cleanup items all dealing with C/R functionality in the trunk.

Restore the "do-not-launch" functionality so users can test a mapping without launching it.
Add a "do-not-resolve" cmd line flag to mpirun so the opal/util/if.c code does not attempt to resolve network addresses, thus enabling a user to test a hostfile mapping without hanging on network resolve requests.
Add a function to hostfile to generate an ordered list of host names from a hostfile
This commit was SVN r18190.
Fix the ompi-server -h cmd line option so it actually tells you something!
Add two new testing codes to the orte/test/mpi area: accept and connect.

Rational (taken from the code):
/* This is PITA. We never know which source address an
* incoming/outgoing packet will have, so even with
* btl_tcp_if_include/exclude on the remote end, we
* might get a different source address.
*
* If this address isn't included in btl_proc->proc_addrs,
* we would erroneously drop the connection

The following SVN revisions from the original message are invalid or
inconsistent and therefore were not cross-referenced:

r18167
Like btl_tcp_disable_family, this parameter more or less disables
a whole address family. Though the sockets are still created, the
corresponding information isn't added to the connection strings.
Likewise, we don't try to connect to addresses matching the disabled
address family.
This is particularly important for multidomain clusters, where IPv4 is
oftenly filtered (firewalled), sometimes by simply dropping the packets
instead of rejecting them (thus causing a connection timeout instead of
a quick "no route to host").

Add the daemon map capability to the ODLS to create and save a map of daemon vpid vs nodename from the launch message.
Cleanup a few places in the base plm launch support where we didn't adequately protect rml recv's from potentially executing sends.
