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.

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.

event/subsystem/bdev: asynchronous SPDK finish First this change moves spdk_subsystem_fini() to trigger on spdk_app_stop(). This ensures that spdk_subsystem_fini() is called before reactors are stopped in spdk_reactors_stop(). Finish paths for subsystems, bdevs and copy engine is now asynchronous. Each of those three mentioned have to make sure they are asynchronous as well. Only bdev that currently has requirement for asynchronous finish are logical volume. Thus the change in vbdev_lvol.c making it move to next bdev module only after all lvol stores were unloaded. Fio_plugin finish of bdev and copy_engine was removed for now. Next patch in series adds it back with async support.
