iotests: Add test for relative backing file names Sometimes, qemu does not have a filename to work with, so it does not know which directory to use for a backing file specified by a relative filename. Add a test which tests that qemu exits with an appropriate error message. Additionally, add a test for qemu-img create with a backing filename relative to the backed image's base directory while omitting the image size.

opts: produce valid command line in qemu_opts_print This will let us print options in a format that the user would actually write it on the command line (foo=bar,baz=asd,etc=def), without prepending a spurious comma at the beginning of the list, or quoting values unnecessarily.

qemu-img: Saner printing of large file sizes Disk sizes close to INT64_MAX cause overflow, for some pretty ridiculous output: $ ./nbdkit -U - memory size=$((2**63 - 512)) --run 'qemu-img info $nbd' image: nbd+unix://?socket=/tmp/nbdkitHSAzNz/socket file format: raw virtual size: -8388607T (9223372036854775296 bytes) disk size: unavailable But there's no reason to have two separate implementations of integer to human-readable abbreviation, where one has overflow and stops at 'T', while the other avoids overflow and goes all the way to 'E'. With this patch, the output now claims 8EiB instead of -8388607T, which really is the correct rounding of largest file size supported by qemu (we could go 511 bytes larger if we used byte-accurate sizing instead of rounding up to the next sector boundary, but that wouldn't change the human-readable result).

=== Non-reconstructable filename ===
block/qapi: allow best-effort query For more complex BDS trees that can be created under normal circumstances, we lose the ability to issue query commands because of our inability to re-construct the absolute filename. Instead, omit this field when it is a problem and present as much information as we can. This will change the expected output in iotest 110, where we will now see a json filename and the lack of an absolute filename instead of an error.

block: Use bdrv_dirname() for relative filenames bdrv_get_full_backing_filename_from_filename() breaks down when it comes to JSON filenames. Using bdrv_dirname() as the basis is better because since we have BDS, we can descend through the BDS tree to the protocol layer, which gives us a greater probability of finding a non-JSON name; also, bdrv_dirname() is more correct as it allows block drivers to override the generation of that directory name in a protocol-specific way. We still need to keep bdrv_get_full_backing_filename_from_filename(), though, because it has valid callers which need it during image creation when no BDS is available yet. This makes a test case in qemu-iotest 110, which was supposed to fail, work. That is actually good, but we need to change the reference output (and the comment in 110) accordingly.

=== Nodes without a common directory ===
block: Generically refresh runtime options Instead of having every block driver which implements bdrv_refresh_filename() copy all of the strong runtime options over to bs->full_open_options, implement this process generically in bdrv_refresh_filename(). This patch only adds this new generic implementation, it does not remove the old functionality. This is done in a follow-up patch. With this patch, some superfluous information (that should never have been there) may be removed from some JSON filenames, as can be seen in the change to iotests 110's and 228's reference outputs.
