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 public headers to include/net, and leave private headers in net/.
Put the virtio headers in include/net/tap.h, removing the multiple copies
that existed. Leave include/net/tap.h as the interface for NICs, and
net/tap_int.h as the interface for OS-specific parts of the tap backend.

Touching char/char.h basically causes the whole of QEMU to
be rebuilt. Avoid this, it is usually unnecessary.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Various header files rely on qemu-char.h including qemu-config.h or
main-loop.h, but they really do not need qemu-char.h at all (particularly
interesting is the case of the block layer!). Clean this up, and also
add missing inclusions of qemu-char.h itself.
