Changelog:

• new global option --dry-run, now implemented for 'subvolume delete'
• fi defrag: new option --step to defragment files in steps, report progress
• balance: removed support for obsolete short syntax 'btrfs balance /path'
• mkfs: print zone count for each device in the overview
• check:
• verify inline ref ordering
• deprecate --clear-space-cache, moved to the 'rescue' group
• rescue clear-space-cache: new command moved from 'btrfs check' implementing the same as option --clear-space-cache (to be deprecated and removed in the future)
• dump-tree: output sequence number for inline refs
• squota: change key number of EXTENT_OWNER_REF_KEY, sync with kernel 6.7-rc1
• property set/get: completely skip char devices, trying to set properties and open /dev/watchdog* causes a reboot
• fix device scanning ioctl definition, accidental change to the 'forget' ioctl that breaks mounting multi-device filesystems
• fixes:
• fi resize: fallback to lowest devid when 1 does not exist, previously the command would fail with "No such device"
• fi usage: fix "devices 0 != 1" message and broken output on multi-device filesystem
• open files in non-blocking mode when reading fsid, this could hang when trying to open fifo files or some special character devices, was observed with 'prop set/get'
• experimental:
• mkfs: parametric zone size for emulated zoned mode
• other:
• cleanups refactoring
• new and updated tests
• CI updates
