qemu-img: TEST_DIR/t.IMGFMT: Refcount width must be a power of two and may not exceed 64 bits
iotests: Make _filter_img_create more active Right now, _filter_img_create just filters out everything that looks format-dependent, and applies some filename filters. That means that we have to add another filter line every time some format gets a new creation option. This can be avoided by instead discarding everything and just keeping what we know is format-independent (format, size, backing file, encryption information[1], preallocation) or just interesting to have in the reference output (external data file path). Furthermore, we probably want to sort these options. Format drivers are not required to define them in any specific order, so the output is effectively random (although this has never bothered us until now). We need a specific order for our reference outputs, though. Unfortunately, just using a plain "sort" would change a lot of existing reference outputs, so we have to pre-filter the option keys to keep our existing order (fmt, size, backing*, data, encryption info, preallocation). Finally, this makes it difficult for _filter_img_create to automagically work for QMP output. Thus, this patch adds a separate _filter_img_create_for_qmp function that echos every line verbatim that does not start with "Formatting", and pipes those "Formatting" lines to _filter_img_create. [1] Actually, the only thing that is really important is whether encryption is enabled or not. A patch by Maxim thus removes all other "encrypt.*" options from the output: https://lists.nongnu.org/archive/html/qemu-block/2020-06/msg00339.html But that patch needs to come later so we can get away with changing as few reference outputs in this patch here as possible.

qemu-img: Flush stdout before before potential stderr messages During 'qemu-img create ... 2>&1', if --quiet is not in force, we can end up with buffered I/O in stdout that was produced before failure, but which appears in output after failure. This is confusing; the fix is to flush stdout prior to attempting anything that might produce an error message. Several iotests demonstrate the resulting ordering change now that the merged outputs now reflect chronology. (An even better fix would be to avoid printf from within block.c altogether, but that's much more invasive...)

qcow2: Use visitor for options in qcow2_create() Instead of manually creating the BlockdevCreateOptions object, use a visitor to parse the given options into the QAPI object. This involves translation from the old command line syntax to the syntax mandated by the QAPI schema. Option names are still checked against qcow2_create_opts, so only the old option names are allowed on the command line, even if they are translated in qcow2_create(). In contrast, new option values are optionally recognised besides the old values: 'compat' accepts 'v2'/'v3' as an alias for '0.10'/'1.1', and 'encrypt.format' accepts 'qcow' as an alias for 'aes' now.

block: Add Error parameter to bdrv_amend_options Looking at the qcow2 code that is riddled with error_report() calls, this is really how it should have been from the start. Along the way, turn the target_version/current_version comparisons at the beginning of qcow2_downgrade() into assertions (the caller has to make sure these conditions are met), and rephrase the error message on using compat=1.1 to get refcount widths other than 16 bits.
