We don't have an equivalent to mmap in the qemu block API, so read and write the bitmap directly. At least in the dumb implementation added in this patch this is a lot less efficient, but it means cow can also work on windows, and over nbd or curl. And it fixes qemu-iotests testcase 012 which did not work properly due to issues with read-only mmap access. In addition we can also get rid of the now unused get_mmap_addr function.
