For existing \file markers, move them to the top of the header and tweak
the wording for consistency.

cf0871a57e ioat: make channel allocation explicit
Add a parameter to each I/OAT library function that requires a channel
instead of implicitly using the thread-local channel registration model.

I/OAT channels are already reported by the spdk_ioat_probe() attach
callback, so no infrastructure for channel allocation is necessary.

04adec22bc Add extern "C" wrapper to all public headers
Also consistently place the extern "C" before any includes or other
declarations in files that already had it.

93933831f7 pci: clean up public pci.h interface
Rename all functions with a spdk_ prefix, and provide enough of an API
to avoid apps needing to #include <pciaccess.h>.

The opaque type used in the public API for a PCI device is now
struct spdk_pci_device *.

047c5aaaa8 ioat: refactor ioat_attach() API into ioat_probe()
Similar to the NVMe API change, this allows better abstraction of the
PCI subsystem.

8aa497f083 spdk: Add block fill API to ioat driver
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.

c02b179490 Remove year from copyright headers.
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./'
