OK, similar copyright - but slightly different problem.
These two lines come from include/migration/qemu-file.h;
they were both added by Daniel in a9cfeb33bb23a81.
The qemu-file.h header however has the old Fabrice copyright
with a 3 paragraph copyright rather than the GPLv2.
So, Authors, and copyright need changing - not sure what the
right way to do the copyright is. Personally I'd ask Dan really
nicely to let it be GPL v2 or newer, but the quicker answer I think
is to take the header from qemu-file.h

Other than that, I'm OK, I hate the '../migration' but if it's
the only way.
