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.

/* SPDX-License-Identifier: BSD-3-Clause
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.

bdev/gpt: support parsing secondary partition table Modify existing code of parsing primary partition table to support parsing the secondary. Main difference of these two tables is that they have inverse buffer layout. For primary table, header is in front of partition entries. And for secondary table, header is after partition entries. So add helper functions to extract header and partition entries buffer region from primary or secondary table based on current parse phase. Split the exported funtion spdk_gpt_parse into two functions spdk_gpt_parse_mbr and spdk_gpt_parse_partition_table. So spdk_gpt_parse_partition_table could be used to parse both primary and secondary table.
