strlcpy breaks WCCP Security
----------------------------

                 Key: TS-1010
                 URL: https://issues.apache.org/jira/browse/TS-1010
             Project: Traffic Server
          Issue Type: Bug
          Components: Network
    Affects Versions: 3.1.0
            Reporter: Alan M. Carroll
            Assignee: Alan M. Carroll


The requirements for WCCP security key handling are precisely those of strncpy -
* The buffer must be zero padded.
* The terminating nul must *not* be copied if the key fills the buffer.
Rather than doing something complex with strlcpy to satisfy these requirements 
it is much easier to simply use strncpy.
