For those Crystal Beach DMA channels which support block fill capability,
we add a fill API here that can zero out pages or fill them with a
fixed pattern.

Also add a space between Copyright and (c).
The copyright year can be determined using git metadata.
Also remove the duplicated "All rights reserved." - every instance of
this line already has a corresponding "All rights reserved" immediately
below it, except for examples/ioat/kperf/kmod/dma_perf.c, where I have
added it manually.
Performed using this command:
git ls-files | xargs sed -i -e 's/Copyright(c) \(.*\) Intel Corporation. All rights reserved./Copyright (c) Intel Corporation./'

_Static_assert is new in C11, and older versions of GCC don't support
it. Detect whether static_assert is available in <assert.h> and if not,
define a fallback macro.

The ioat library currently only supports DMA copy operations, but the
hardware can do other types of transfers. Add a union of the hardware
descriptor structures to enable support for the other operations in the
future.
Also add a generic hardware descriptor type to allow access to the parts
of the descriptor that are common between all types.
