`UnknownArrayHandle` has special behavior when putting in or getting out
an `ArrayHandleMultiplexer` or an `ArrayHandleCast`. When putting in
either of these, `UnknownArrayHandle` gets the actual array stored in
the multiplexer and cast so that you can later retrieve the base array.
Likewise, when you get the array out with `AsArrayHandle`, you can give
it an `ArrayHandleCast` or `ArrayHandleMultiplexer`, and you will get
the base array placed inside of it.
The Visual Studio compiler has an annoying habit where if you use a
templated class or method with a deprecated class as a template
parameter, you will get a deprecation warning where that class is used
in the templated thing. Thus, if you want to suppress the warning, you
have to supress every instance of the template, not just where the
template is declared.
This is annoying behavior that is thankfully not replicated in other
compilers.
The implementation of `VariantArrayHandle` has been changed to be a
relatively trivial subclass of `UnknownArrayHandle`.
The advantage of this change is twofold. First, it removes
`VariantArrayHandle`'s dependence on `ArrayHandleVirtual`, which gets us
much closer to deprecating that class. Second, it ensures that
`UnknownArrayHandle` is a reasonable replacement for
`VariantArrayHandle`, so we can move forward with replacing that.

C++11 introduced the `std::vector::data()` method. In addition to being
more syntatically pleasing, it should correctly handle the condition
when the `std::vector` is size 0 and therefore has no real pointer.
(Expressions like `&v[0]` are undefined when the `vector` is empty.)
The new method `ArrayHandle::DeepCopy` had the pattern such that the
data in the `this` array was pushed to the provided destination array.
However, this is the opposite pattern used in the equivalent method in
VTK, which takes the data from the provided array and copies it to
`this` array.
So, swap the pattern to match that of VTK. Also, make the method name
more descriptive by renaming it to `DeepCopyFrom`. Hopefully, users will
read that to mean given the `ArrayHandle`, you copy data from the other
provided `ArrayHandle`.
A recent modification to `ArrayCopy` created a fast path for when
copying arrays of the same type. This fast path just deep copies the
buffers. The issue was that the buffer copy was creating new buffers
instead of updating the existing buffers. The passed in `ArrayHandle`
would get updated to the new buffers, but any other `ArrayHandle`s
sharing those buffers would still have the old versions. That would lead
to unexpected errors in code like this.
```cpp
vtkm::cont::ArrayHandle<T> outArray1;
vtkm::cont::ArrayHandle<T> outArray2 = outArray1;
vtkm::cont::ArrayCopy(inArray, outArray2);
```
If `inArray` was a different type than `outArray2`, then the data for
both `outArray1` and `outArray2` would be updated (which is the expected
behavior for something considered a "pointer"). However, if `inArray`
was the same type as `outArray2`, then the fast path would change
`outArray2` but leave `outArray1` the same.
This behavior has been corrected so that, in this case, the data of
`outArray1` always follows that of `outArray2`.
The parallel sorts in the device adapter are documented to not be
stable. Up until recently, the sorts for all the supported devices
happened to be stable (or at least provided a stable sort where needed).
However, the recent Kokkos adapter provides a sort that is no stable.
This broke some tests that relied on stable sorts when they should not
have.
Fix the tests that relied on stable sort to check the results.
