Fix undefined behaviors reported by UBSan

We have some undefined behaviors reported under clang compiler.

You can check the current status at https://jenkins.aws.isc.org/job/kea-dev/job/jenkins-tests-report/Jenkins_20Tests_20Report/ on the ut-ubsan tab.

Here are most of them from https://jenkins.aws.isc.org/job/kea-dev/job/ut-ubsan/508/.
