A recent change removed the thread indices parameters from the arguments
to the `Fetch` template. Somehow, an instance of using the old template
in the CUDA task strided tests snuck through the dashboard tests.
Correct that.

This change is needed for being able to use different thread indices types
without changing Fetchs. Basically decoupling those two areas.
1. This commit removes concrete specialization instantiations of
ThreadIndicesTypes in all of the Fetch's specializations.
2. It also moves the ThreadIndicesType template parameter from the Fetch
struct to a template parameter in their methods Load/Store.

This fixes, which where triggered since in the new CI, one of the
docker runner set `OMP_NUM_THREADS=3`:
1. `UnitTestOpenMPDeviceAdapter`
2. `UnitTestMeshQualityFilter`
In the redution optimized implementation for _OpenMP_, it unrolls
the reduce loop in iterations of four elements. The last iteration
in the loop might overflow the loop end element (when it is not a
multiple of four).
This commit fixes this by setting the OpenMP unrolled reduce loop
end element to its previous closest multiple of four of the original end
element.

If you gave ReduceByKey a fancy output array that decorated another
array, you could get a runtime error for using an invalid array (if the
device adapter used the generic algorithm). The problem was that
ReduceByKey creates a temporary array, and that array was given the same
storage as the output array. That might not be valid for fancy arrays,
so instead use the default storage for the temporary array.
If you gave ScanInclusiveByKey a fancy output array that decorated
another array, you would get a runtime error for using an invalid array.
The problem was that ScanInclusiveByKey creates a temporary output array
and then copies the result to the actual output array. The problem was
that the temporary output array was given the same storage as the output
array, which won't work if the output array is fancy. Instead, make the
storage for the temporary array default.

The `ArrayHandleStreaming` class stems from an old research project
experimenting with bringing data from an `ArrayHandle` in parts and
overlapping device transfer and execution. It works, but only in very
limited contexts. Thus, it is not actually used today. Plus, the feature
requires global indexing to be permutated throughout the worklet
dispatching classes of VTK-m for no further reason.
Because it is not really used, there are other more promising approaches
on the horizon, and it makes further scheduling improvements difficult,
we are removing this functionality.
One of the execution tests, UnitTestScatterAndMaskWithTopology,
was defining a hierarchy of worklets that defined a virtual
operator(). It mostly still worked since the code was executed
with the final type and thus did not actually need to look up
the virtual table. However, some invalid memory access must have
been happening in CUDA since under some unpredictable circumstances
a memory protection error was happening.
This fixes the problem by removing the virtual methods.

With recent changes to allow a configuration to change the default
types, storage, and cell sets, it is possible to feed filters and other
components types they were not previously expecting. Fix feature gaps
where these components were not accepting the types they should.
Previously, the PolicyDefault used to compile all the filters was hard-
coded. The problem was that if any external project that depends on VTK-
m needs a different policy, it had to recompile everything in its own
translation units with a custom policy.
This change allows an external project provide a simple header file that
changes the type lists used in the default policy. That allows VTK-m to
compile the filters exactly as specified by the external project.
Read-only arrays (usually) do not define Set methods. Thus, using one in
an Invoke argument that does output will result in compile errors. To
help avoid that, modify the type checks to differentiate input and
output arrays.

As a general C++ "rule of three," if one of a copy constructor, copy
assignment, or destructor is defined, all three should be defined. Some
compilers issue warnings if this rule of three is violated.
It is sometimes the case that we define a destructor simply because it
is only valid in the control environment. When doing so, add
implementations for copy constructor and assignment as well.
Previously, the ArrayPortalCheck wrapper did not allow access to the
superclass' Get for 3D indices. This solves that problem and also fixes
it for Set (assuming there is ever an instance of that).
After lots of experimenting, it appears that VS 2015 has problems when
you list a variate template argument before a normal template argument
in a specialization of a function, The compiler seems happy when the
variate argument is placed at the end of the template arguments.
The nvcc compiler was having problem resolving a template partial
specialization that contained a template param with its own number
list and another param that depended on that template.
`integer_sequence` is an essential tool when dealing with structures
like a `Tuple`. Make sure that we have one (even though it was not
introduced until C++14).
Currently, VTK-m is using C++11. However, it is often useful to use
features in the `std` namespace that are defined for C++14 or later. We
can provide our own versions (sometimes), but it is preferable to use
the version provided by the compiler if available.
There were already some examples of defining portable versions of C++14
and C++17 classes in a `vtkmstd` namespace, but these were sprinkled
around the source code.
There is now a top level `vtkmstd` directory and in it are header files
that provide portable versions of these future C++ classes. In each
case, preprocessor macros are used to select which version of the class
to use.
Made a new vtkm::Tuple class to replace tao tuple.
This version of Tuple should hopefully compile faster. Having our own
implementation should also make it easier to port to new devices.
Previously, when a ReadPortal or a WritePortal was returned from an
ArrayHandle, it had wrapped in it a Token that was attached to the
ArrayHandle. This Token would prevent other reads and writes from the
ArrayHandle.
This added safety in the form of making sure that the ArrayPortal was
always valid. Unfortunately, it also made deadlocks very easy. They
happened when an ArrayPortal did not leave scope immediately after use
(which is not all that uncommon).
Now, the ArrayPortal no longer locks up the ArrayHandle. Instead, when
an access happens on the ArrayPortal, it checks to make sure that
nothing has happened to the data being accessed. If it has, a fatal
error is reported to the log.
Even if an error condition occurs, the output parameter should be
initialized to something. This makes the behavior predicatable on error
conditions and prevents uninitialized variable warnings.
This is a flag that functions in the execution environment can return to
report on the status of the operation. This way they can report an error
without forcing the entire invocation to shut down.
