This patch creates a new commonlib/bsd subdirectory with a similar purpose to the existing commonlib, with the difference that all files under this subdirectory shall be licensed under the BSD-3-Clause license (or compatible permissive license). The goal is to allow more code to be shared with libpayload in the future. Initially, I'm going to move a few files there that have already been BSD-licensed in the existing commonlib. I am also exracting most contents of the often-needed <commonlib/helpers.h> as long as they have either been written by me (and are hereby relicensed) or have an existing equivalent in BSD-licensed libpayload code. I am also relicensing <commonlib/compression.h> (written by me) and <commonlib/compiler.h> (same stuff exists in libpayload). Finally, I am extracting the cb_err error code definitions from <types.h> into a new BSD-licensed header so that future commonlib/bsd code can build upon a common set of error values. I am making the assumption here that the enum constants and the half-sentence fragments of documentation next to them by themselves do not meet the threshold of copyrightability.
