This is an initial commit that still needs some reworking
and debugging.

This does a bunch of name changing of files, data structures,
and variables from 'cuda' to 'device' in order to reflect which
things are generic device functionality vs. tied to a specific
language. In addition, this now compiles and runs a simple program
that calls HYPRE_Init() and allocates/copies/frees memory on the
device and host with unified memory.

Quick fix for compilation --with-cuda. Ran some tests on lassen
and quartz as well to make sure I didn't break the cuda or cpu
versions.

Modified csr matvec to choose the default execution policy
instead of hard-coded device policy. This now passes tests
and seems to run as expected using sycl unified memory and
using host execution for everything.

Starting to put in boxloop sycl code. This compiles,
but crashes.

I have fixed my compilation issues and can now run with my
sycl boxloop1 implementation on frank's sever machine. The
boxloop1 code seems to be giving correct results as well,
though it seems somewhere along the line I screwed up the
struct solvers tests, which yield a discrepancy in number of
iterations for the first solvers.jobs job.

The non-reduction boxloops are all in and pass the struct tests.
Performance is VERY slow, but this may just be due to the machine
I am running on. Reduction boxloops are in progress.

The reduction boxloops are implemented and pass the
struct solvers.sh tests. Cleanup of boxloop_sycl.h.

Uses shared memory pointer instead of buffers and accessors.
Seems to work on iris, same error as before on arcticus.
