Add sereval hmp commands for incremental backup.
It need a bitmap to backup data from drive-image to incremental image,
so before it need add bitmap for this device to track io.
Usage:
drive_backup [-n] [-f] device target [bitmap] [format]
Example:
# qemu-img create -f qcow2 /path/incremental-1.qcow2 -b /path/full.qcow2
(qemu) block_dirty_bitmap_add drive-virtio-disk0 bitmap0
(qemu) drive-backup -n drive-virtio-disk0 /path/incremental-1.qcow2 bitmap0
