Make it easier to copy all the persistent bitmaps of (the top layer

shorthand, as the same effect could be accomplished with a series of
'qemu-img bitmap --add' and 'qemu-img bitmap --merge -b source'
commands, or by QMP commands.
Note that this command will fail in the same scenarios where 'qemu-img
measure --bitmaps' fails, when either the source or the destanation
destination
lacks persistent bitmap support altogether.
If we remove --bitmaps option from qemu-img measure, we need to remove
this note.
Or rather, adjust it to state that "this command will fail in the
scenarios where 'qemu-img measure' omits a 'bitmaps size:' output line.
