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.

When starting QEMU management apps will usually setup a monitor socket, and
then open it immediately after startup. If not using QEMU's own -daemonize
arg, this process can be troublesome to handle correctly. The mgmt app will
need to repeatedly call connect() until it succeeds, because it does not
know when QEMU has created the listener socket. If can't retry connect()
forever though, because an error might have caused QEMU to exit before it
even creates the monitor.
The obvious way to fix this kind of problem is to just pass in a pre-opened
socket file descriptor for the QEMU monitor to listen on. The management
app can now immediately call connect() just once. If connect() fails it
knows that QEMU has exited with an error.
The SocketAddress(Legacy) structs allow for FD passing via the monitor, and
now via inherited file descriptors from the process that spawned QEMU. The
final missing piece is adding a 'fd' parameter in the socket chardev
options.
This allows both HMP usage, pass any FD number with SCM_RIGHTS, then
running HMP commands:
getfd myfd
chardev-add socket,fd=myfd
Note that numeric FDs cannot be referenced directly in HMP, only named FDs.
And also CLI usage, by leak FD 3 from parent by clearing O_CLOEXEC, then
spawning QEMU with
-chardev socket,fd=3,id=mon
-mon chardev=mon,mode=control
Note that named FDs cannot be referenced in CLI args, only numeric FDs.
We do not wire this up in the legacy chardev syntax, so you cannot use FD
passing with '-qmp', you must use the modern '-mon' + '-chardev' pair.
When passing pre-opened FDs there is a restriction on use of TLS encryption.
It can be used on a server socket chardev, but cannot be used for a client
socket chardev. This is because when validating a server's certificate, the
client needs to have a hostname available to match against the certificate
identity.
An illustrative example of usage is:
#!/usr/bin/perl
use IO::Socket::UNIX;
use Fcntl;
unlink "/tmp/qmp";
my $srv = IO::Socket::UNIX->new(
Type => SOCK_STREAM(),
Local => "/tmp/qmp",
Listen => 1,
);
my $flags = fcntl $srv, F_GETFD, 0;
fcntl $srv, F_SETFD, $flags & ~FD_CLOEXEC;
my $fd = $srv->fileno();
exec "qemu-system-x86_64", \
"-chardev", "socket,fd=$fd,server,nowait,id=mon", \
"-mon", "chardev=mon,mode=control";

Introduce ChardevClass.chr_machine_done() hook so that chardevs can run
customized procedures after machine init.
There was an existing mux user already that did similar thing but used a
raw machine done notifier. Generalize it into a framework, and let the
mux chardevs provide such a class-specific hook to achieve the same
thing. Then we can move the mux related code to the char-mux.c file.
Since at it, replace the mux_realized variable with the global
machine_init_done varible.
This notifier framework will be further leverged by other type of
chardevs soon.

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.

In QEMU's main_loop() we used to check whether we should do
a nonblocking call to main_loop(); this was deleted in commit e330c118f2,
because now that vCPUs always drop the I/O thread lock it is an unnecessary
optimization.
The loop in test-char.c copied the old QEMU main_loop() code, but
here the nonblocking check has never been necessary because this
standalone test case doesn't hold the I/O lock anyway. Remove it,
so we can drop the main_loop_wait() return value.
