We test the behaviour of an `IndexInput` using `randomReadAndSlice()` which uses a wide varity of different access methods to read the data. Lucene sometimes calls `clone()` and `slice()` concurrently, although it does ensure that there are no concurrent readers while these are being called. Today we do not verify that our `IndexInput`s behave correctly under this kind of concurrent access. This commit extracts `randomReadAndSlice()` into a separate test harness for more general consumption and adds support for concurrent cloning and slicing.
