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.

lib/trace_parser: add trace_parser library stubs This library will provide functions that parse traces recorded by an SPDK application. This includes merging traces from multiple cores, sorting them by their timestamp and constructing trace entries spanning across multiple buffers. All of these tasks are currently implemented in the spdk_trace app, so most of its code will be moved here (this is the reason for using C++). The motivation for extracting this code to a library is to be able to use it from places other than the spdk_trace app, specifically the `scripts/bpf/trace.py` script. The main reason for creating a separate library instead of extending libtrace is to avoid pulling in all of its dependencies. ISA-L is the most problematic, as we only build it as a static library, which makes it impossible to use with dlopen (making it unusable in scripts).

nvme/pcie, nvme/tcp: add cb_arg context tracepoint argument This allows mapping an nvme_request back to the nvme_bdev_io. This requires bumping up the max number of arguments per tracepoint. 5 was previously chosen as max since it exactly fit in 64 bytes (1 cacheline) when all arguments were stored as uint64_t, but now that we support uint32_t arguments we can afford extra arguments when some of them are uint32_t. I've bumped it to 8 so we can avoid having to touch this value multiple times if we find some cases where we need 7 or 8 args.
