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.

bdev: rename blockdev instances to bdev This includes file names, functions, #defines, etc. There are still a few uses of "blockdev" outside of include/ and lib/ - these can be handled later. This preps for a future patch to consolidate vbdev modules and bdev modules into just bdev modules.

bdev: make construct RPCs return the bdev names When creating a bdev via the RPC interface, there was no way to know what name it was assigned (other than predicting it based on the numbering scheme). Change all of the relevant RPC interfaces to return an array of bdev names so they can be used to construct LUNs/subsystems dynamically in scripts.
