s390x/kvm: Rework cmma management
Let's keep track of cmma enablement and move the mem_path check into
the actual enablement. This now also warns users that do not use
cpu-models about disabled cmma when using huge pages.

s390x/flic: introduce modify_ais_mode callback
In order to emulate the adapter interruption suppression (AIS)
facility properly, the guest needs to be able to modify the AIS mask.
Interrupt suppression will be handled via the flic (for kvm, via a
recently introduced kernel backend; for !kvm, in the flic code), so
let's introduce a method to change the mode via the flic interface.
We introduce the 'simm' and 'nimm' fields to QEMUS390FLICState
to store interruption modes for each ISC. Each bit in 'simm' and
'nimm' targets one ISC, and collaboratively indicate three modes:
ALL-Interruptions, SINGLE-Interruption and NO-Interruptions. This
interface can initiate most transitions between the states; transition
from SINGLE-Interruption to NO-Interruptions via adapter interrupt
injection will be introduced in a following patch. The meaningful
combinations are as follows:
interruption mode | simm bit | nimm bit
------------------|----------|----------
ALL | 0 | 0
SINGLE | 1 | 0
NO | 1 | 1

s390x/flic: introduce inject_airq callback
Let's introduce a specialized way to inject adapter interrupts that,
unlike the common interrupt injection method, allows to take the
characteristics of the adapter into account.
For adapters subject to AIS facility:
- for non-kvm case, we handle the suppression for a given ISC in QEMU.
- for kvm case, we pass adapter id to kvm to do airq injection.
Add add tracepoint for suppressed airq and suppressing airq.

s390x: add css_migration_enabled to machine class
Currently the migration of the channel subsystem (css) is only partial
and is done by the virtio ccw proxies -- the only migratable css devices
existing at the moment.
With the current work on emulated and passthrough devices we need to
decouple the migration of the channel subsystem state from virtio ccw,
and have a separate section for it. A new section however necessarily
breaks the migration compatibility.
So let us introduce a switch at the machine class, and put it in 'off'
state for now. We will turn the switch 'on' for future machines once all
preparations are met. For compatibility machines the switch will stay
'off'.

s390x/css: add missing css state conditionally
Although we have recently vmstatified the migration of some css
infrastructure, for some css entities there is still state to be
migrated left, because the focus was keeping migration stream
compatibility (that is basically everything as-is).
Let us add vmstate helpers and extend existing vmstate descriptions so
that we have everything we need. Let us guard the added state via
css_migration_enabled, so we keep the compatible behavior if css
migration is disabled.
Let's also annotate the bits which do not need to be migrated for better
readability.

pc-bios/s390-ccw: Add code for virtio feature negotiation
The upcoming virtio-net driver needs to negotiate some features,
so we need the possibility to do this in the core virtio code.

Log Message:

pc-bios/s390: add s390-netboot.img
It's already possible to do a network boot of an s390x guest with an
external netboot image based on a Linux installation, but it would
be much more convenient if the s390-ccw firmware supported network
booting right out of the box, without the need to assemble such an
external image first.
This is an s390-netboot.img that can be used for network booting.
You can download a combined kernel + initrd image via TFTP
by starting QEMU for example with:
qemu-system-s390x ... -device virtio-net,netdev=n1,bootindex=1 \
-netdev user,id=n1,tftp=/path/to/tftp,bootfile=kernel.img
Note that this version does not support downloading via config
files (i.e. pxelinux config files or .INS config files) yet. This
will be added later.

s390x/cpumodel: add zpci, aen and ais facilities
zPCI instructions and facilities are available since IBM zEnterprise
EC12. To support z/PCI in QEMU we enable zpci, aen and ais facilities
starting with zEC12 GA1. And we always set zpci and aen bits in max cpu
model. Later they might be switched off due to applied real cpu model.
For ais bit, we only provide it in the full cpu model beginning with
zEC12 and defer its enablement in the default cpu model to a later point
in time. At the same time, disable them for 2.9 and older machines.
Because of introducing AIS facility, we could check if it's enabled to
initialize flic->ais_supported with the real value.

s390x/cpumodel: we are always in zarchitecture mode
In QEMU, a guest VCPU always started in and never was able to leave
z/Architecture mode. Now we have an architected way of showing this
condition.
The SIGP SET ARCHITECTURE instruction is simply rejected. Linux as guest
seems to not care about the return value, which is a good thing
The new handling is just like already being in z/Architecture mode.
We'll not try to fake absence of this facility, but still not indicate
the facility in case some strange CPU model turned z/Architecture off
completely (which doesn't work either way but let's us see how a
guest would react on a lack of this facility).
