With all targets defining CPU_RESOLVING_TYPE, refactor
cpu_parse_cpu_model(type, cpu_model) to parse_cpu_model(cpu_model)
so that callers won't have to know internal resolving cpu
type. Place it in exec.c so it could be called from both
target independed vl.c and *-user/main.c.
That allows us to stop abusing cpu type from
MachineClass::default_cpu_type
as resolver class in vl.c which were confusing part of
cpu_parse_cpu_model().
Also with new parse_cpu_model(), the last users of cpu_init()
in null-machine.c and bsd/linux-user targets could be switched
to cpu_create() API and cpu_init() API will be removed by
follow up patch.
With no longer users left remove MachineState::cpu_model field,
new code should use MachineState::cpu_type instead and
leave cpu_model parsing to generic code in vl.c.

Postcopy migration of dirty bitmaps. Only named dirty bitmaps are migrated.
If destination qemu is already containing a dirty bitmap with the same name
as a migrated bitmap (for the same node), then, if their granularities are
the same the migration will be done, otherwise the error will be generated.
If destination qemu doesn't contain such bitmap it will be created.

Now instead of using the replay_lock to guard the output of the log we
now use it to protect the whole execution section. This replaces what
the BQL used to do when it was held during TCG execution.
We also introduce some rules for locking order - mainly that you
cannot take the replay_mutex while holding the BQL. This leads to some
slight sophistry during start-up and extending the
replay_mutex_destroy function to unlock the mutex without checking
for the BQL condition so it can be cleanly dropped in the non-replay
case.

Since commit 67a1de0d195a there is no space anymore between the
version number and the parentheses when running configure with
--with-pkgversion=foo :
$ qemu-system-s390x --version
QEMU emulator version 2.11.50(foo)
But the space is included when building without that option
when building from a git checkout:
$ qemu-system-s390x --version
QEMU emulator version 2.11.50 (v2.11.0-1494-gbec9c64-dirty)
The same confusion exists with the "query-version" QMP command.
Let's fix this by introducing a proper QEMU_FULL_VERSION definition
that includes the space and parentheses, while the QEMU_PKGVERSION
should just cleanly contain the package version string itself.
Note that this also changes the behavior of the "query-version" QMP
command (the space and parentheses are not included there anymore),
but that's supposed to be OK since the strings there are not meant
to be parsed by other tools.

We have that variable but not exported. Export that so modules can have
a way to poke on whether machine init has finished.
Meanwhile, set that up even before calling the notifiers, so that
notifiers who may depend on this field will get a correct answer.

Commit 00d09fdbbae5f7864ce754913efc84c12fdf9f1a ("vl: pause vcpus before
stopping iothreads") and commit dce8921b2baaf95974af8176406881872067adfa
("iothread: Stop threads before main() quits") tried to work around the
fact that emulation was still active during termination by stopping
iothreads. They suffer from race conditions:
1. virtio_scsi_handle_cmd_vq() racing with iothread_stop_all() hits the
virtio_scsi_ctx_check() assertion failure because the BDS AioContext
has been modified by iothread_stop_all().
2. Guest vq kick racing with main loop termination leaves a readable
ioeventfd that is handled by the next aio_poll() when external
clients are enabled again, resulting in unwanted emulation activity.
This patch obsoletes those commits by fully disabling emulation activity
when vcpus are stopped.
Use the new vm_shutdown() function instead of pause_all_vcpus() so that
vm change state handlers are invoked too. Virtio devices will now stop
their ioeventfds, preventing further emulation activity after vm_stop().
Note that vm_stop(RUN_STATE_SHUTDOWN) cannot be used because it emits a
QMP STOP event that may affect existing clients.
It is no longer necessary to call replay_disable_events() directly since
vm_shutdown() does so already.
Drop iothread_stop_all() since it is no longer used.

There are two issues with the documentation of the --balloon parameter:
First, "--balloon none" is simply doing nothing. Even if a machine had a
balloon device by default, this option is not disabling anything, it is
simply ignored. Thus let's simply drop this option from the documentation
to avoid to confuse the users (but keep the code in vl.c for backward
compatibility).
Second, the documentation claims that "--balloon virtio" is the default
mode, but this is not true anymore since commit 382f074371f7dc32a34.
Since that commit, the option also has no real use case anymore, since
you can simply use "--device virtio-balloon" nowadays instead. Thus to
simplify our complex parameter zoo a little bit, let's deprecate the
the parameter now and tell the user to use "--device virtio-balloon"
instead.

The legacy "-net" option can be quite confusing for the users since most
people do not expect to get a "vlan" hub between their emulated guest
hardware and the host backend. But so far, we are also not able to get
rid of "-net" completely, since it is the only way to configure on-board
NICs that can not be instantiated via "-device" yet. It's also a little
bit shorter to type "-net nic -net tap" instead of "-device xyz,netdev=n1
-netdev tap,id=n1".
So what we need is a new convenience option that is shorter to type than
the full -device + -netdev stuff, and which can be used to configure the
on-board NICs that can not be handled via -device yet. Thus this patch now
provides such a new option "--nic": It adds an entry in the nd_table to
configure a on-board / default NIC, creates a host backend and connects
the two directly, without a confusing "vlan" hub inbetween.

The previous commit improved compile time by including less of the
generated QAPI headers. This is impossible for stuff defined directly
in qapi-schema.json, because that ends up in headers that that pull in
everything.
Move everything but include directives from qapi-schema.json to new
sub-module qapi/misc.json, then include just the "misc" shard where
possible.
It's possible everywhere, except:
* monitor.c needs qmp-command.h to get qmp_init_marshal()
* monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need
qapi-event.h to get enum QAPIEvent
Perhaps we'll get rid of those some other day.

In my "build everything" tree, a change to the types in
qapi-schema.json triggers a recompile of about 4800 out of 5100
objects.
The previous commit split up qmp-commands.h, qmp-event.h, qmp-visit.h,
qapi-types.h. Each of these headers still includes all its shards.
Reduce compile time by including just the shards we actually need.
To illustrate the benefits: adding a type to qapi/migration.json now
recompiles some 2300 instead of 4800 objects. The next commit will
improve it further.

This patch is the s390 implementation of guest crash information,
similar to commit d187e08dc4 ("i386/cpu: add crash-information QOM
property") and the related commits. We will detect several crash
reasons, with the "disabled wait" being the most important one, since
this is used by all s390 guests as a "panic like" notification.
Demonstrate these ways with examples as follows.
1. crash-information QOM property;
Run qemu with -qmp unix:qmp-sock,server, then use utility "qmp-shell"
to execute "qom-get" command, and might get the result like,
(QEMU) (QEMU) qom-get path=/machine/unattached/device[0] \
property=crash-information
{"return": {"core": 0, "reason": "disabled-wait", "psw-mask": 562956395872256, \
"type": "s390", "psw-addr": 1102832}}
2. GUEST_PANICKED event reporting;
Run qemu with a socket option, and telnet or nc to that,
-chardev socket,id=qmp,port=4444,host=localhost,server \
-mon chardev=qmp,mode=control,pretty=on \
Negotiating the mode by { "execute": "qmp_capabilities" }, and the crash
information will be reported on a guest crash event like,
{
"timestamp": {
"seconds": 1518004739,
"microseconds": 552563
},
"event": "GUEST_PANICKED",
"data": {
"action": "pause",
"info": {
"core": 0,
"psw-addr": 1102832,
"reason": "disabled-wait",
"psw-mask": 562956395872256,
"type": "s390"
}
}
}
3. log;
Run qemu with the parameters: -D <logfile> -d guest_errors, to
specify the logfile and log item. The results might be,
Guest crashed on cpu 0: disabled-wait

The "default" parameter of the "-mon" option is useless since
QEMU v2.4.0, and marked as deprecated since QEMU v2.8.0. That
should have been long enough to let people update their scripts,
so time to remove it now.

Commit dce8921b2baaf95974af8176406881872067adfa ("iothread: Stop threads
before main() quits") introduced iothread_stop_all() to avoid the
following virtio-scsi assertion failure:
assert(blk_get_aio_context(d->conf.blk) == s->ctx);
Back then the assertion failed because when bdrv_close_all() made
d->conf.blk NULL, blk_get_aio_context() returned the global AioContext
instead of s->ctx.
The same assertion can still fail today when vcpus submit new I/O
requests after iothread_stop_all() has moved the BDS to the global
AioContext.
This patch hardens the iothread_stop_all() approach by pausing vcpus
before calling iothread_stop_all().
Note that the assertion failure is a race condition. It is not possible
to reproduce it reliably.

This cleanup makes the number of objects depending on qapi/error.h
drop from 1910 (out of 4743) to 1612 in my "build everything" tree.
While there, separate #include from file comment with a blank line,
and drop a useless comment on why qemu/osdep.h is included first.

System headers should be included with <...>, our own headers with
"...". Offenders tracked down with an ugly, brittle and probably
buggy Perl script. Previous iteration was commit a9c94277f0.
Delete inclusions of "string.h" and "strings.h" instead of fixing them
to <string.h> and <strings.h>, because we always include these via
osdep.h.
Put the cleaned up system header includes first.
While there, separate #include from file comment with exactly one
blank line.

The option have been marked as deprecated since QEMU 2.10, and so far
nobody complained that the host, serial, disk and net options are urgently
required anymore. So let's now get rid at least of this legacy pile, to
simplify the usb code quite a bit.
This patch removes the usbdevices host, serial, disk and net. These devices
use their own complicated parameter parsing mechanisms, so they are just
ugly to maintain, without real benefit for the users (the users can use the
corresponding "-device" parameters instead which have the same complexity
as the "-usbdevice" devices here).
Note that the other rather simple -usbdevice options (mouse, tablet, etc.)
are not removed yet (the code is really simple here, so it does not hurt
much to keep it), as well as the two devices "braille" and "bt" which are
easier to use with -usbdevice than with -device.

Drop no_frame flag from sdl_display_init argument list, use a global
variable instead. This is temporary until -no-frame support is dropped
altogether when we remove sdl1 support.
Remove any traces of noframe from sdl2 code. It is just dead code as
sdl2 doesn't support the SDL_NOFRAME window flag any more.

Remove dependency of possible_cpus on 1st CPU instance,
which decouples configuration data from CPU instances that
are created using that data.
Also later it would be used for enabling early cpu to numa node
configuration at runtime qmp_query_hotpluggable_cpus() should
provide a list of available cpu slots at early stage,
before machine_init() is called and the 1st cpu is created,
so that mgmt might be able to call it and use output to set
numa mapping.
Use MachineClass::possible_cpu_arch_ids() callback to set
cpu type info, along with the rest of possible cpu properties,
to let machine define which cpu type* will be used.
* for SPAPR it will be a spapr core type and for ARM/s390x/x86
a respective descendant of CPUClass.
Move parse_numa_opts() in vl.c after cpu_model is parsed into
cpu_type so that possible_cpu_arch_ids() would know which
cpu_type to use during layout initialization.
