Complement the previous patch by starting the VM with a QMP command.
The plan is that the user will be able to do the same, invoking two
commands "finish-machine-init" and "cont" instead of
"x-exit-preconfig".

Make qemu_start_incoming_migration local to migration/migration.c.
By using the runstate instead of a separate flag, vl need not do
anything to setup deferred incoming migration.
qmp_migrate_incoming also does not need the deferred_incoming flag
anymore, because "-incoming PROTOCOL" will clear the "once" flag
before the main loop starts. Therefore, later invocations of
the migrate-incoming command will fail with the existing
"The incoming migration has already been started" error message.

Displays should be available before the monitor starts, so that
it is possible to use the graphical console to interact with
the monitor itself.
This patch is quite ugly, but all this is temporary. The double
call to qemu_init_displays will go away as soon we can unify machine
initialization between the preconfig and "normal" flows, and so will
the preconfig_exit_requested variable (that is only preconfig_requested
remains).

This is a bit nasty: the machine is storing a string and later
resolving it. We probably want to remove the memdev property
and instead make this a memory-set command. "-M memdev" can be
handled a legacy option that is special cased by

qemu_opts_set is used to create default network backends and to
parse sugar options -kernel, -initrd, -append, -bios and -dtb.
These are very different uses:
I would *expect* a function named qemu_opts_set to set an option in a
merge-lists QemuOptsList, such as -kernel, and possibly to set an option
in a non-merge-lists QemuOptsList with non-NULL id, similar to -set.
However, it wouldn't *work* to use qemu_opts_set for the latter
because qemu_opts_set uses fail_if_exists==1. So, for non-merge-lists
QemuOptsList and non-NULL id, the semantics of qemu_opts_set (fail if the
(QemuOptsList, id) pair already exists) are debatable.
On the other hand, I would not expect qemu_opts_set to create a
non-merge-lists QemuOpts with a single option; which it does, though.
For this case of non-merge-lists QemuOptsList and NULL id, qemu_opts_set
hardly adds value over qemu_opts_parse. It does skip some parsing and
unescaping, but that's not needed when creating default network
backends.
So qemu_opts_set has warty behavior for non-merge-lists QemuOptsList
if id is non-NULL, and it's mostly pointless if id is NULL. My
solution to keeping the API as simple as possible is to limit
qemu_opts_set to merge-lists QemuOptsList. For them, it's useful (we
don't want comma-unescaping for -kernel) *and* has sane semantics.
Network backend creation is switched to qemu_opts_parse.
qemu_opts_set is now only used on merge-lists QemuOptsList... except
in the testcase, which is changed to use a merge-list QemuOptsList.
With this change we can also remove the id parameter. With the
parameter always NULL, we know that qemu_opts_create cannot fail
and can pass &error_abort to it.

Keep the machine initialization sequence free of miscellaneous command
line parsing actions.
The only difference is that preallocation will always be done with one
thread if -smp is not provided; previously it was using mc->default_cpus,
which is almost always 1 anyway.

Just like -incoming. Later we will add support for "-incoming defer
-preconfig", because there are cases (Xen, block layer) that want
to look at RUNSTATE_INMIGRATE. -loadvm will remain mutually exclusive
with preconfig; the plan is to just do loadvm in the monitor, since
the user is already going to interact with it for preconfiguration.

for the option. The option only works for the latest version

Windows where this option is not supported.
