Make it easier to copy all the persistent bitmaps of (the top layer of) a source image along with its guest-visible contents, by adding a boolean flag for use with qemu-img convert. This is basically 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 their corresponding QMP commands. Note that this command will fail in the same scenarios where 'qemu-img measure' omits a 'bitmaps size:' line, namely, when either the source or the destination lacks persistent bitmap support altogether. See also https://bugzilla.redhat.com/show_bug.cgi?id=1779893 While touching this, clean up a couple coding issues spotted in the same function: an extra blank line, and merging back-to-back 'if (!skip_create)' blocks.
