KVM/qemu patches
- patch rate is high, documentation is low, review is low
- patches
are in master branch, and patches for qemu-kvm.git are in
kemari-v0.1.1-kvm.
I would split 23 patches into small chunks and send it separately to make
reviewing easier, and hopefully have feedbacks.
Thanks,
Yoshi

Introduce ft_tranx_ready() which kicks the FT transaction cycle. When
ft_mode is on, migrate_fd_put_ready() would open ft_transaction file
and turn on event_tap. To end or cancel ft_transaction, ft_mode and
event_tap is turned off.

This code implements VM transaction protocol. Like buffered_file, it
sits between savevm and migration layer. With this architecture, VM
transaction protocol is implemented mostly independent from other
existing code.

When ft_mode is set in the header, tcp_accept_incoming_migration()
receives ft_transaction iteratively. We also need a hack no to close
