We want to use the same code base for TCG, so let's cleanly factor it
out.
The sigp mutex is currently not really needed, as everything is
protected by the iothread mutex. But this could change later, so leave
it in place and initialize it properly from common code.

Provides an interface for getting and setting the guest's extended
TOD-Clock via a single ioctl to kvm. If the ioctl fails because it
is not support by kvm, then we fall back to the old style of
retrieving the clock via two ioctls.

[some cosmetic fixes]
Let's do it just like the other architectures. Introduce kvm-stub.c
for stubs and kvm_s390x.h for the declarations.
Change license to GPL2+ and keep copyright notice.
As we are dropping the sysemu/kvm.h include from cpu.h, fix up includes.
