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.
