Now that we can safely call QOBJECT() on QObject * as well as its
subtypes, we can have macros qobject_ref() / qobject_unref() that work
everywhere instead of having to use QINCREF() / QDECREF() for QObject
and qobject_incref() / qobject_decref() for its subtypes.
The replacement is mechanical, except I broke a long line, and added a
cast in monitor_qmp_cleanup_req_queue_locked(). Unlike
qobject_decref(), qobject_unref() doesn't accept void *.
Note that the new macros evaluate their argument exactly once, thus no
need to shout them.

Test the new OOB capability. It's mostly the reverted OOB test
(see commit 4fd78ad7), but differs in that:
- It uses the new qtest_init_without_qmp_handshake() parameter to
create the monitor with "x-oob"
- Squashed the capability tests on greeting message
- Don't use qtest_global any more, instead use self-maintained
QTestState, which is the trend

Allow callers to choose whether to allow OOB support during a test;
for now, all existing callers pass false, but the next patch will
add a new caller. Also, rewrite the monitor setup to be generic

This reverts commit 3fd2457d18.
Enabling OOB caused several iotests failures; due to the imminent
2.12 release, the safest action is to disable OOB for now. If
other patches fix the issues that iotests exposed, it may be turned
back on in time for the release, otherwise it will be 2.13 material;
either way, the framework changes not reverted now do not hurt if
they remain as part of the 2.12 release.
Additionally, revert the tests in the patch 02130314d8 ("qmp: introduce
QMPCapability", 2018-03-19), as both parts must be reverted at once
to keep 'make check' passing.

There were no QMP capabilities defined. Define the first capability,
"oob", to allow out-of-band messages.
After this patch, we will allow QMP clients to enable QMP capabilities
when sending the first "qmp_capabilities" command. Originally we are
starting QMP session with no arguments like:
{ "execute": "qmp_capabilities" }
Now we can enable some QMP capabilities using (take OOB as example,
which is the only capability that we support):
{ "execute": "qmp_capabilities",
"arguments": { "enable": [ "oob" ] } }
When the "arguments" key is not provided, no capability is enabled.
For capability "oob", the monitor needs to be run on a dedicated IO
thread, otherwise the command will fail. For example, trying to enable
OOB on a MUXed typed QMP monitor will fail.
One thing to mention is that QMP capabilities are per-monitor, and also
when the connection is closed due to some reason, the capabilities will
be reset.
Also, touch up qmp-test.c to test the new bits.

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.
Adding a type to qapi/migration.json now recompiles some 120 instead
of 2300 out of 5100 objects.

As a general rule, we prefer avoiding implicit global state
because it makes code harder to safely copy and paste without
thinking about the global state. Although qmp-test does not
maintain parallel qtest connections, it was the last test
assigning to global_qtest. It's just as easy to be explicit
about the state; once all tests have been cleaned up, a later
patch can then get rid of global_qtest and a layer of wrappers
in libqtest.

A command is a query if it has no side effect and yields a result.
Such commands are typically named query-FOO, but there are exceptions.
The basic idea is to find candidates with query-qmp-schema, filter out
the ones that aren't queries with an explicit blacklist, and test the
remaining ones against a QEMU with no special arguments.
The current blacklist is just add-fd.
The test can't do queries with arguments, because it knows nothing
about the arguments. No coverage for query-cpu-model-baseline,
query-cpu-model-comparison, query-cpu-model-expansion, query-rocker,
query-rocker-ports, query-rocker-of-dpa-flows, and
query-rocker-of-dpa-groups.
Most tested commands are expected to succeed. The test does not check
the return value then.
query-balloon and query-vm-generation-id are expected to fail because
they need a virtio-balloon / vmgenid device to succeed, and this test
is too dumb to set one up. Could be addressed later.
query-acpi-ospm-status and query-hotpluggable-cpus are expected to
fail because they require features provided only by special machine
types, and this test is too dumb to set that up. Could also be
addressed later.
Several commands may either be functional or stubs that always fail,
depending on build configuration. Ideally, the stubs shouldn't be in
query-qmp-schema, but that requires QAPI schema compile-time
configuration, which we don't have, yet. Until we do, we need to
figure out whether a command is a stub. When we have a suitable
CONFIG_FOO preprocessor symbol is available, use that. Else,
simply blacklist the command for now.
We get basic test coverage for the following commands, except as
noted:
qom-list-types
query-acpi-ospm-status (expected to fail)
query-balloon (expected to fail)
query-block
query-block-jobs
