bdev/aio: Add UUID to the bdev_aio_create function

Adds an optional UUID to the RPC call. The parameter is persisted upon
save_config call. This allows for the bdev to have a consistent UUID and
means it can be used with RAID bdev.

bdev/aio: support UNMAP

Support UNMAP by fallocate FALLOC_FL_PUNCH_HOLE.

Note that fallocate() is synchronous syscall, reactor would block
until operations to disk complete. This could significantly hurt
performance. For general purpose, AIO based UNMAP(even WRITE ZERO)
is *not* suggested to be used in production environment. Instead of
an entire NVMe bdev, we can test UNMAP in regular file based
development environment.

Suggested by Changpeng, support RPC command to enable *fallocate* for
a single AIO bdev(rather than enabling this feature for all the AIO
bdev at compiling step), this looks appropriate enough.

update Intel copyright notices

per Intel policy to include file commit date using git cmd
below. The policy does not apply to non-Intel (C) notices.

git log --follow -C90% --format=%ad --date default <file> | tail -1

and then pull just the 4 digit year from the result.

Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc). Contribution date used
"--follow -C95%" to get the most accurate date.

Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line. Simply there for
consistency.

Replace most BSD 3-clause license text with SPDX identifier.

Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file. This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.

Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text. There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".

Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.
