2017-06-28migration: move skip_section_footersPeter Xu
Move it into MigrationState, revert its meaning and renaming it to send_section_footer, with a property bound to it. Same trick is played like previous patches. Removing savevm_skip_section_footers().

2017-06-28migration: move skip_configuration outPeter Xu
It was in SaveState but now moved to MigrationState altogether, reverted its meaning, then renamed to "send_configuration". Again, using HW_COMPAT_2_3 for old PC/SPAPR machines, and accel_register_prop() for xen_init(). Removing savevm_skip_configuration().

2017-06-28migration: move only_migratable to MigrationStatePeter Xu
One less global variable, and it does only matter with migration. We keep the old "--only-migratable" option, but also now we support: -global migration.only-migratable=true Currently still keep the old interface. Hmm, now vl.c has no way to access migrate_get_current(). Export a function for it to setup only_migratable.

2017-06-28migration: move global_state.optional outPeter Xu
Put it into MigrationState then we can use the properties to specify whether to enable storing global state. Removing global_state_set_optional() since now we can use HW_COMPAT_2_3 for x86/power, and AccelClass.global_props for Xen.

2017-06-28migration: let MigrationState be a qdevPeter Xu
Let the old man "MigrationState" join the object family. Direct benefit 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. No functional change at all.

2017-06-28vl: clean up global property registrationPeter Xu
It's not that clear on how the global properties are registered to global_props (and also its priority relationship).

2017-06-28accel: introduce AccelClass.global_propsPeter Xu
Introduce this new field for the accelerator classes so that each specific accelerator in the future can register its own global properties to be used further by the system. It works just like how the old machine compatible properties do, but only tailored for accelerators. Introduce register_compat_props_array() for it. Export it so that it may be used in other codes as well in the future.

2017-06-28machine: export register_compat_prop()Peter Xu
We have HW_COMPAT_*, however that's only bound to machines, not other things (like accelerators). Behind it, it was register_compat_prop() that played the trick. Let's export the function for further use outside HW_COMPAT_* magic. Meanwhile, move it to qdev-properties.c where seems more proper (since it'll be used not only in machine codes).

We need to be careful to handle both requests that call the completion callback directly from the calling coroutine (i.e. fully synchronous code) and requests that involve some callback, so that we need to yield and wait for the completion callback coming from outside the coroutine.
