[ClusterLabs Developers] resource-agents send_arp pull request, fixes RH Bugz#1250728

[Lars Ellenberg]

Just to make you all aware of

IPaddr2 send_arp causes a buffer overflow on infiniband devices
https://bugzilla.redhat.com/show_bug.cgi?id=1250728

send_arp: fix for infiniband, re-merge from upstream iputils arping #654 
https://github.com/ClusterLabs/resource-agents/pull/654

If no-one has any objections, I'll merge that next week.

We can then discuss how to best clean up the IPaddr* RA
(drop references to "ipoibarping").
