This adds SPDX license headers in place of the wide assortment of things currently in our script headers. We default to GPL-2.0-only except for the oeqa code where it was clearly submitted and marked as MIT on the most part or some scripts which had the "or later" GPL versioning. The patch also drops other obsolete bits of file headers where they were encoountered such as editor modelines, obsolete maintainer information or the phrase "All rights reserved" which is now obsolete and not required in copyright headers (in this case its actually confusing for licensing as all rights were not reserved). More work is needed for OE-Core but this takes care of the bulk of the scripts and meta/lib directories. The top level LICENSE files are tweaked to match the new structure and the SPDX naming.

QEMU network configuration script to bring down tap devices. This
utility needs to be run as root, and will use the tunctl binary
from the native sysroot.
If you find yourself calling this script a lot, you can add the
the following to your /etc/sudoers file to be able to run this
command without entering your password each time:
ALL=NOPASSWD: /path/to/runqemu-ifup
