virtio-console: qdev conversion, new virtio-serial-bus

This commit converts the virtio-console device to create a new
virtio-serial bus that can host console and generic serial ports. The
file hosting this code is now called virtio-serial-bus.c.

The virtio console is now a very simple qdev device that sits on the...

S390: Bail out without KVM

Currently only the S390 KVM target works. To keep users from accidently not
using KVM, let's not even initialize the machine when KVM is not used.

S390: Loop through virtio console devices

We used to always create one single virtio console device. This breaks when
either zero of multiple virtio console devices are requested, so let's use
the same code as on x86.

s390: fix build on 32 bit host

Building on 32 bit host we get:
hw/s390-virtio.c: In function ‘s390_init’:
hw/s390-virtio.c:184: error: integer constant is too large for ‘unsigned long’ type
64 bit values must be ULL.

Set default console to virtio on S390x

All "normal" system emulation targets in qemu I'm aware of display
output on either VGA or serial output.

Add S390x virtio machine description

In order to use the new S390x virtio bus we just introduced, we also
need a machine description that sets up the machine according to our
PV specification.

Let's add that machine description and be happy!
