Without this series, the process for copying one qcow2 image to
another including all of its bitmaps involves running qemu and doing
the copying by hand with a series of QMP commands.  This makes the
process a bit more convenient.

I still think that someday we will need a 'qemu-img bitmap' with
various subcommands for manipulating bitmaps within an offline image,
but in the meantime, this seems like a useful addition on its own.

Series can also be downloaded at:
