Out-of-band command execution was introduced in commit cf869d5317.
Unfortunately, we ran into a regression, and had to turn it into an
experimental option for 2.12 (commit be933ffc23).
http://lists.gnu.org/archive/html/qemu-devel/2018-03/msg06231.html
The regression has since been fixed (commit 951702f39c "monitor: bind
dispatch bh to iohandler context"). A thorough re-review of OOB
commands led to a few more issues, which have also been addressed.
This patch partly reverts be933ffc23 (monitor: new parameter "x-oob"),
and makes QMP monitors again offer capability "oob" whenever they can
provide it, i.e. when the monitor's character device is capable of
running in an I/O thread.
Some trivial touch-up in the test code is required to make sure qmp-test
won't break.

When a QMP client sends in-band commands more quickly that we can
process them, we can either queue them without limit (QUEUE), drop
commands when the queue is full (DROP), or suspend receiving commands
when the queue is full (SUSPEND). None of them is ideal:
* QUEUE lets a misbehaving client make QEMU eat memory without bounds.
Not such a hot idea.
* With DROP, the client has to cope with dropped in-band commands. To
inform the client, we send a COMMAND_DROPPED event then. The event is
flawed by design in two ways: it's ambiguous (see commit d621cfe0a1),
and it brings back the "eat memory without bounds" problem.
* With SUSPEND, the client has to manage the flow of in-band commands to
keep the monitor available for out-of-band commands.
We currently DROP. Switch to SUSPEND.
Managing the flow of in-band commands to keep the monitor available for
out-of-band commands isn't really hard: just count the number of
"outstanding" in-band commands (commands sent minus replies received),
and if it exceeds the limit, hold back additional ones until it drops
below the limit again.
Note that we need to be careful pairing the suspend with a resume, or
else the monitor will hang, possibly forever. And here since we need to
make sure both:
(1) popping request from the req queue, and
(2) reading length of the req queue
will be in the same critical section, we let the pop function take the
corresponding queue lock when there is a request, then we release the
lock from the caller.

Because spice code tries to emit a "disconnected" signal on the
monitors. Fix this dead-lock by releasing the monitor lock for
flush/destroy.
monitor_lock protects mon_list, monitor_qapi_event_state and
monitor_destroyed. monitor_flush() and monitor_data_destroy() don't
access any of those variables.
monitor_cleanup()'s loop is safe because it uses
QTAILQ_FOREACH_SAFE(), and no further monitor can be added after
calling monitor_cleanup() thanks to monitor_destroyed check in
monitor_list_append().

monitor_cleanup() is one of the last things main() calls before it
returns. In the following patch, monitor_cleanup() will release the
monitor_lock during flushing. There may be pending commands to insert
new monitors, which would modify the mon_list during iteration, and
the clean-up could thus miss those new insertions.
Add a monitor_destroyed global to check if monitor_cleanup() has been
already called. In this case, don't insert the new monitor in the
list, but free it instead. A cleaner solution would involve the main
thread telling other threads to terminate, waiting for their
termination.

Assert we don't switch context when the character device doesn't

Existing frontend that rely on context switching would now assert() if

So far we only had implicit requirements for the minimum compiler version,
e.g. we require at least GCC 4.1 for the support of atomics. However,
such old compiler versions are not tested anymore by the developers, so
they are not really supported anymore. Since we recently declared explicitly
what platforms we intend to support, we can also get more explicit on the
compiler version now. The supported distributions use the following version
of GCC:
RHEL-7: 4.8.5
Debian (Stretch): 6.3.0
Debian (Jessie): 4.8.4
OpenBSD (ports): 4.9.4
FreeBSD (ports): 8.2.0
OpenSUSE Leap 15: 7.3.1
Ubuntu (Xenial): 5.3.1
macOS (Homebrew): 8.2.0
So we can safely assume GCC 4.8 these days. For Clang, the situation is
a little bit more ambiguous, since it is sometimes not available in the
main distros but rather third party repositories. At least Debian Jessie
uses version 3.5, and EPEL7 for RHEL7 uses 3.4, so let's use 3.4 as
minimum Clang version now - we still can adjust this later if necessary.
Unfortunately Apple uses different version numbers for the Clang that is
included in their Xcode suite, so we need to check the version numbers
for Xcode separately. Xcode 5.1 seems to be the first one that has been
shipped with LLVM 3.4, so use this version as the minimum there.

Instead of setting suppress_vmdesc at instance_init time, set

This will let us eliminate the need for pc_compat_*() functions

host_memory_backend_set_host_nodes() was not validating

Fix the crash and add a simple regression test for the fix.
While at it, fix memory leak of the list returned by
visit_type_uint16List().

The intended functionality of QMP `cpu-add` is replaced with
`device_add` (and `query-hotpluggable-cpus`). So let's deprecate
`cpu-add`.
A complete example of vCPU hotplug with the recommended way (using
`device_add`) is provided as part of a seperate docs patch.
