Streamline test skipping based on supported features
...
This adds a new test decorator: skip_unless_feature(). The argument is
the same as passed to features.check(). If the feature is not supported,
the test will be skipped.
This removes several kinds of boilerplate copied and pasted around tests
so test feature checking is handled and displayed more consistently.
