Now that we have a thread, and blocking writes, we don't need it.

Move all the writes to the migration_thread, and make writings
blocking. Notice that are still using the iothread for everything
that we do.

We want the file assignment to happen before the thread is created to
avoid locking, so we just do it before creating the thread.

We still protect everything except the wait with the iothread lock.
But we moved from a timer to a thread. Steps one by one.
We also need to detect when we have finished with a variable "complete".

Add the new mutex that protects shared state between ram_save_live
and the iothread. If the iothread mutex has to be taken together
with the ramlist mutex, the iothread shall always be _outside_.

This will be used to detect if last_block might have become invalid
across different calls to ram_save_live.

Most of the time, only 2 items will be active (from/to for a string operation,
or code/data). But TCG guests likely won't have gigabytes of memory, so
this actually goes down to 1 item.

The call in buffered_close is enough, because buffered_close is called
already by migrate_fd_cleanup.

Move bindings from opaque to DeviceState.
This gives us better type safety with no performance cost.
Add macros to make future QOM work easier.

Document that the x86 CPU refactorings are going through the qom-cpu
tree. This does not contradict the established practice that patches
adding KVM features to the x86 CPU go through the KVM maintainers,
it merely takes it out of target-i386 TCG's Odd Fixes status.

This separates the qdev properties code in two parts:
- qdev-properties.c, that contains most of the qdev properties code;
- qdev-properties-system.c for code specific for qemu-system-*,
containing:
- Property types: drive, chr, netdev, vlan, that depend on code that
won't be included on *-user
- qemu_add_globals(), that depends on qemu-config.o.
This change should help on two things:
- Allowing DeviceState to be used by *-user without pulling
dependencies that are specific for qemu-system-*;
- Writing qdev unit tests without pulling too many dependencies.
The copyright/license of qdev-properties.c isn't explicitly stated at
the file, so add a simple copyright/license header pointing to the
commit ID of the original file.
