Previously, the number of buffers held by an `ArrayHandle` had to be
determined statically at compile time by the storage. Most of the time
this is fine. However, there are some exceptions where the number of
buffers need to be selected at runtime. For example, the
`ArrayHandleRecombineVec` does not specify the number of components it
uses, and it needed a hack where it stored buffers in the metadata of
another buffer, which is bad.
This change allows the number of buffers to vary at runtime (at least at
construction). The buffers were already managed in a `std::vector`. It
now no longer forces the vector to be a specific size.
`GetNumberOfBuffers` was removed from the `Storage`. Instead, if the
number of buffers was not specified at construction, an allocation of
size 0 is done to create default buffers.
The biggest change is to the interface of the storage object methods,
which now take `std::vector` instead of pointers to `Buffer` objects.
This adds a little hastle in having to copy subsets of this `vector`
when a storage object has multiple sub-arrays. But it does simplify some
of the templating.
The `vtkm_unit_tests` function in the CMake build now allows you to specify
which files need to be compiled with a device compiler using the
`DEVICE_SOURCES` argument. Previously, the only way to specify that unit
tests needed to be compiled with a device compiler was to use the
`ALL_BACKENDS` argument, which would automatically compile everything with
the device compiler as well as test the code on all backends.
`ALL_BACKENDS` is still supported, but it no longer changes the sources to
be compiled with the device compiler.
What was previously declared as `ArrayHandleNewStyle` is now just the
implementation of `ArrayHandle`. The old implementation of `ArrayHandle`
has been moved to `ArrayHandleDeprecated`, and `ArrayHandle`s still
using this implementation must declare `VTKM_ARRAY_HANDLE_DEPRECATED` to
use it.
`ArrayExtractComponent` allows you to get a component of an array.
Unlike `ArrayHandleExtractComponent`, the type you get is always the
same: an `ArrayHandleStride`. This way, you can get an array that
contains the data of an extracted component with less templating and
potentially dramatically reduce the amount of code generated (although
some runtime integer arithmetic is added).
One of the dashboard compilers (gcc 4.8 with cuda, I think) was giving
warnings about an unused parameter. Apparently, the compiler did not
like the parameters defined for `default` assignment operators.
The old version of ExecutionObject (that only takes a device) is still
supported, but you will get a deprecated warning if that is what is
defined.
Supporing this also included sending vtkm::cont::Token through the
vtkm::cont::arg::Transport mechanism, which was a change that propogated
through a lot of code.

This patch removes (or conditionally removes) the Set method from
portals that are read-only so that IsWritableArrayHandle will work as
expected. The ArrayPortal doxygen has been updated to reflect this.
The remaining exceptions are `ArrayPortalVirtual` and
`ArrayPortalMultiplexer`, since their mutability cannot be determined at
compile time.
Sandia National Laboratories recently changed management from the
Sandia Corporation to the National Technology & Engineering Solutions
of Sandia, LLC (NTESS). The copyright statements need to be updated
accordingly.
This is part of #43, which will ultimately simplify the
ArrayHandleCompositeVector to a new implementation that can be easily
written to. Part of this effort will remove the ability to pull a single
component from a vector-typed input ArrayHandle for use in the
CompositeVector, and this new class makes sure we can still support that
usecase.
