Still we don't want to publish compress and copy-range options, as 1. Modern way to enable compression is to use compress filter. 2. For copy-range it's unclean how to make proper interface: - it's has experimental prefix for backup job anyway - the whole BackupPerf structure doesn't make sense for the filter So, let's just add copy-range possibility to the filter later if needed. Still, we are going to continue support for compression and experimental copy-range in backup job. So, set these options after filter creation. Note, that we can drop "compress" argument of bdrv_cbw_append() now, as well as "perf". The only reason not doing so is that now, when I prepare this patch the big series around it is already reviewed and I want to avoid extra rebase conflicts to simplify review of the following version.
