John Newbery 232b6665bc Allow test cases to be skipped
Currently, functional test cases can either pass or fail. There are
occasions when it is helpful to skip tests, for example if the
system they are running on does not meet the requirements for the test.
The rest of the test suite can run without being marked as a failure.

This commit adds framework for tests to skip if their requirements
aren't met.
