Two minor changes to the copyright and license marking for these files: (1) Stacey D Son is used instead of variations of his name. (2) The GPL boilerplate is replaced by SPDX markings. No change to the terms of the license are intended, and this matches current QEMU practice. There's no changes to the license or additional claims to any IP that others may hold in these files. All the S-o-bs in this commit have given me permission to do this to the extent they may hold rights. git blame over multiple repos and branches suggests that only minimal other material is present (much of it likely not subject to copyright protection). The project's long and complex history as well as tooling limitations make it hard to be 100% sure. Any omissions are unintentional and I will correct them as they come to light.
