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: more ZERO_BUFFER_SIZE to bdev_internal.h The bdevio test app has some test cases verifying that write zeroes commands are handled correctly, but using knowledge of the ZERO_BUFFER_SIZE that the bdev library uses for splitting larger write zeroes commands. Instead of hardcoding that 1MB value in bdevio.c, have bdevio.c use ZERO_BUFFER_SIZE directly instead. But this requires moving ZERO_BUFFER_SIZE into bdev_internal.h and having bdevio.c include that file. We do this instead of putting ZERO_BUFFER_SIZE in the public API because we don't want users to make any kind of dependencies on this value. While here, also rename the tests that are using this value, so that the test names don't include any reference to the specific size of this bdev-internal zero buffer size.

bdev: Add counts per I/O error status into I/O statistics Define struct spdk_bdev_io_error_stat privately in lib/bdev/bdev.c. Add a pointer to struct spdk_bdev_io_error_stat to struct spdk_bdev_io_stat. Allocate spdk_bdev_io_error_stat for bdev and RPC, but do not allocate spdk_bdev_io_error_stat for I/O channel. Dump the contents of spdk_bdev_io_error_stat only if its total is non-zero. As a result of these, only spdk_bdev_get_device_stat() can query spdk_bdev_io_error_stat for the bdev_get_iostat RPC.
