445b552d3a Try again to get an error message printed when a daemon fails to successfully report back to mpirun. In this case, there is no guaranteed way for the daemon to output the error report itself - we don't have a connection back to the HNP, and we have tied stderr off to /dev/null (for good reasons). So the HNP has to detect the failure itself and report it. 
The HNP can't know the precise reason, of course - all it knows is that the daemon failed. So output a generic error message that provides guidance on probable causes.

f3cae3d6f3 Cleanup the handling of if_include and if_exclude arguments based on CIDR notation. 
Fix a bug in the new code that prevented the system from correctly matching addresses.

Remove comments in the show-help text indicating that we would continue in the face of incorrect specifications - leave that to the calling layer to decide.

Modify the new opal_ifmatches so it returns error codes letting the caller better understand the result.

Modify the oob to ensure we abort if we don't find interfaces matching specified constraints, and that we do so without multiple error messages.

NOTE: we have a conflict in our standards. We have been using comma-delimited lists of interfaces for all our params. However, one param - opal_net_private_ipv4 - now uses semicolons instead of comma separators. No idea why, but it is confusing.

1491d52bd7 Extend the parsing capability of the oob tcp module's if_include and if_exclude options to support subnet+mask notation, and to handle virtual IP addresses (it was previously having problems distinguishing between "eth1" and "eth1.3").

d98fc311e9 Restore the ability to specify a range of dynamic ports for use by the TCP OOB module. The range can now be specified as any combination of ranges (e.g., 1-5,8,10,21-30). The system will error out if you attempt to specify both static and dynamic ports.
