Eric Blake 47829c4079 nbd/client: Make x-dirty-bitmap more reliable ... The implementation of x-dirty-bitmap in qemu 3.0 (commit 216ee365) silently falls back to treating the server as not supporting NBD_CMD_BLOCK_STATUS if a requested meta_context name was not negotiated, which in turn means treating the _entire_ image as data. Since our hack relied on using 'qemu-img map' to view which portions of the image were dirty by seeing what the redirected bdrv_block_status() treats as holes, this means that our fallback treats the entire image as clean. Better would have been to treat the entire image as dirty, or to fail to connect because the user's request for a specific context could not be honored. This patch goes with the latter.
