qemu-img: Add bitmap sub-command Include actions for --add, --remove, --clear, --enable, --disable, and --merge (note that --clear is a bit of fluff, because the same can be accomplished by removing a bitmap and then adding a new one in its place, but it matches what QMP commands exist). Listing is omitted, because it does not require a bitmap name and because it was already possible with 'qemu-img info'. A single command line can play one or more bitmap commands in sequence on the same bitmap name (although all added bitmaps share the same granularity, and and all merged bitmaps come from the same source file). Merge defaults to other bitmaps in the primary image, but can also be told to merge bitmaps from a distinct image. While this supports --image-opts for the file being modified, I did not think it worth the extra complexity to support that for the source file in a cross-file merges. Likewise, I chose to have --merge only take a single source rather than following the QMP support for multiple merges in one go (although you can still use more than one --merge in the command line); in part because qemu-img is offline and therefore atomicity is not an issue. Upcoming patches will add iotest coverage of these commands while also testing other features.

qemu-img: add the 'dd' subcommand This patch adds a basic dd subcommand analogous to dd(1) to qemu-img. For the start, this implements the bs, if, of and count options and requires both if and of to be specified (no stdin/stdout if not specified) and doesn't support tty, pipes, etc. The image format must be specified with -O for the output if the raw format is not the intended one. Two tests are added to test qemu-img dd.

qemu-img rebase This adds a rebase subcommand to qemu-img which allows to change the backing file of an image. In default mode, both the current and the new backing file need to exist, and after the rebase, the COW image is guaranteed to have the same guest visible content as before. To achieve this, old and new backing file are compared and, if necessary, data is copied from the old backing file into the COW image. With -u an unsafe mode is enabled that doesn't require the backing files to exist. It merely changes the backing file reference in the COW image. This is useful for renaming or moving the backing file. The user is responsible to make sure that the new backing file has no changes compared to the old one, or corruption may occur.
