[PROBLEM] Btrfstune allows multiple different options to be executed in one go, some options are completely fine, like no-holes along with extref, but with more and more options, we need more exclusive checks. In fact a lot of new options are already not following the old success/total checks. [ENHANCEMENT] There is really no need to allow multiple features to be set in one go. So this patch introduces an array which groups all the compatible options into following categories: - Extent tree This includes converting to/from extent and block group tree. - Space cache This includes converting to v2 space cache. - Metadata UUID This includes changing metadata uuid. - FSID change This includes the slower full fs fsid rewrites. - Csum change This includes the csum rewrites. - Seed devices This includes changing the device seed flag. - Legacy options This includes no-holes/extref/skinny-metadata features, which are already default mkfs features. Now we only allow options inside the same group to be specified. E.g. "btrfstune -r -S 1" would fail as it includes both legacy and seed groups. Meanwhile "btrfstune -r -n" would still be allowed.
