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: 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.
