[ofiwg] coverity report

[Hefty, Sean]

Ever since the OFA server was upgraded, our coverity scans have been disabled.  (Coverity won't run on the new OFA OS.)  I was able to manually generate a coverity build and upload the results for analysis.  Those results are now available:

Maintainers -- please look at the report and provide any fixes.  I'd like to get those in prior to the 1.7 release, with 1.7.0rc1 targeted for the week of 11/26.

I'm working to make this process less manual by having coverity automatically run against a specific branch as part of Travis CI, but, well, let's call that a work in progress.
