Fixes for some issues found using Coverity

[Kittel, Martin]

Hi,

we ship krb5 as part of some of our products and as part of our QA we run Coverity scans on all components, including krb5.
As part of these scans a number of issues were found that we think need or might need fixing. I am wondering now how to best feed back those fixes into the mainline
I have prepared a first bunch of git commits against the current HEAD from https://github.com/krb5/krb5 and tried to group them according to the Coverity findings. However I don't know whether I can feed these into krb5-bugs directly. What is the preferred way to post such patches?

Thanks and best wishes,

Martin.
