[bind10-dev] git hook to prevent security branches

[Jeremy C. Reed]

I put a pre-receive git hook in place to prevent security branches.

If any reference name contains secur, vulnerab, or privat (uppercase 
or lowercase) it is denied.

I did a few tests. But it may need some more testing. We will talk about 
this during our phone call.

Then we will document this.
