Change the way the IP options report problems

The error messages are not needed or used as these are not processing errors
so much as errors to be reported back to the packet sender. Implicitly
describe whether each error should generate ICMP packets or not. Most do
but there are a couple that do not.

Slightly alter some test expectations for Linux compatibility and add a
couple more. Improve Linux compatibility on error packet returns. Some
cosmetic changes to tests to match the upcoming packet impact version
of the same tests.
