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.

bdev/malloc: Use options structure to create a malloc bdev Define a options structure, malloc_bdev_opts, and use it directly for the bdev_malloc_create RPC. To do this, bdev_malloc.h includes bdev_module.h instead of bdev.h to have the definition of the struct spdk_uuid, and the struct malloc_bdev_opts has a instance of struct spdk_uuid. Clean up file inclusion together. Furthermore, use spdk_uuid_copy() to copy uuid from the malloc_bdev_opts to the malloc disk rather than the = operator, and remove a duplicated size check. These are helpful to add more parameters for creation.

bdev/malloc: Support both of interleaved and separated metadata The malloc bdev module supports both of interleaved and separated metadata in this patch. Different from the NULL bdev module, opts->block_size is a data block size and a block size is caculated internally as a sum of opts->block_size and opts->md_size if opts->md_interleave is true, or opts->block_size otherwise. This will be more intuitive. Additionally, opts->md_size accepts only either of 0, 8, 16, 32, 64, or 128. Protection information (T10 DIF/DIX) will be supported in the following patches.

bdev/malloc: Support protection information for read and write For write, verify DIF/DIX before submission and for read, verify DIF/DIX after successful completion. As same as the NVMe bdev module and the NULL bdev module, DIF/DIX verification is done based on the DIF type and DIF insert/strip is not supported. In near future, the bdev I/O APIs bring an I/O flag to the underlying bdev and the malloc bdev module will be able to decide DIF/DIX verification based on the I/O flag. One important feature is to setup protection information when creating a malloc disk. Otherwise, all initial reads will fail if protection information is enabled. For users, add some explanation about the dif_type parameter into doc/jsonrpc.md.
