This completely refactors the `expectsError` behavior: so far it's almost identical to `assert.throws(fn, object)` in case it was used with a function as first argument. It had a magical property check that allowed to verify a functions `type` in case `type` was passed used in the validation object. This pattern is now completely removed and `assert.throws()` should be used instead. The main intent for `common.expectsError()` is to verify error cases for callback based APIs. This is now more flexible by accepting all validation possibilites that `assert.throws()` accepts as well. No magical properties exist anymore. This reduces surprising behavior for developers who are not used to the Node.js core code base. This has the side effect that `common` is used significantly less frequent.
