migrate-set-parameters sets migration parameters according to is
arguments like this:
* Present means "set the parameter to this value"
* Absent means "leave the parameter unchanged"
* Except for parameters tls_creds and tls_hostname, "" means "reset
the parameter to its default value
The first two are perfectly normal: presence of the parameter makes
the command do something.
The third one overloads the parameter with a second meaning. The
overloading is *implicit*, i.e. it's not visible in the types. Works
here, because "" is neither a valid TLS credentials ID, nor a valid
host name.
Pressing argument values the schema accepts, but are semantically
invalid, into service to mean "reset to default" is not general, as
suitable invalid values need not exist. I also find it ugly.
To clean this up, we could add a separate flag argument to ask for
"reset to default", or add a distinct value to @tls_creds and
@tls_hostname. This commit implements the latter: add JSON null to
the values of @tls_creds and @tls_hostname, deprecate "".
Because we're so close to the 2.10 freeze, implement it in the
stupidest way possible: have qmp_migrate_set_parameters() rewrite null
to "" before anything else can see the null. The proper way to do it
would be rewriting "" to null, but that requires fixing up code to
work with null. Add TODO comments for that.

Commit de63ab6 "migrate: Share common MigrationParameters struct"
reused MigrationParameters for the arguments of
migrate-set-parameters, with the following rationale:
It is rather verbose, and slightly error-prone, to repeat
the same set of parameters for input (migrate-set-parameters)
as for output (query-migrate-parameters), where the only
difference is whether the members are optional. We can just
document that the optional members will always be present
on output, and then share a common struct between both
commands. The next patch can then reduce the amount of
code needed on input.
I need to unshare them to correct a design flaw in a stupid, but
minimally invasive way, in the next commit. We can restore the
sharing when we redo that patch in a less stupid way. Add a suitable
TODO comment.
Note that I revert only the sharing part of commit de63ab6, not the
part that made the members of query-migrate-parameters' result
optional. The schema (and thus introspection) remains inaccurate for
query-migrate-parameters. If we decide not to restore the sharing, we
should revert that part, too.

we'll ignore all the capabilities if we detected invalid setup along the

When this capability is enabled, QEMU will use the return path even for
precopy migration. This is helpful at least in one case when destination
failed to load the image while source quited without confirmation. With
return path, source will wait for the last response from destination,
and if destination fails, it'll fail the migration on source, then the
guest can be run again on the source (rather than assuming to be good,
then the guest will be lost after source quits).
It needs to be enabled explicitly on source, otherwise disabled.

These two parameters:
- MachineState::enforce_config_section
- MigrationState::send_configuration
are playing similar role here. This patch merges the first one into
second, then we'll have a single place to reference whether we need to
send the configuration section.
I didn't remove the MachineState.enforce_config_section field since when
applying that machine property (in machine_set_property()) we haven't
yet initialized global properties and migration object. Then, it's
still not easy to pass that boolean to MigrationState at such an early
time.
A natural benefit for current patch is that now we kept the meaning of
"enforce-config-section" since it'll still have the highest
priority (that's what "enforce" mean I guess).

is that we can start to use all the property features derived from
current QDev, like: HW_COMPAT_* bits, command line setup for migration
parameters (so will never need to set them up each time using HMP/QMP,
this is really, really attractive for test writters), etc.
I see no reason to disallow this happen yet. So let's start from this
one, to see whether it would be anything good.
Now we init the MigrationState struct statically in main() to make sure
it's initialized after global properties are applied, since we'll use
them during creation of the object.

Previously, dst side will immediately try to lock the write byte upon
receiving QEMU_VM_EOF, but at src side, bdrv_inactivate_all() is only
done after sending it. If the src host is under load, dst may fail to
acquire the lock due to racing with the src unlocking it.
Fix this by hoisting the bdrv_inactivate_all() operation before
QEMU_VM_EOF.
N.B. A further improvement could possibly be done to cleanly handover
locks between src and dst, so that there is no window where a third QEMU
could steal the locks and prevent src and dst from running.
