Btrfs progs release 6.19

[David Sterba <dsterba@suse.com>]

Hi,

btrfs-progs version 6.19 have been released (ther version 6.18 has been skipped).

There's change in mkfs.btrfs defaults, the block group tree is now enabled. A
note is printed (which was a last minute change and the release was redone, the
top commit is 9ac9a97ee3ebcc71).

Changelog:

* mkfs:
  * make block-group-tree default (support since linux 6.1), use -O ^bgt to
    unset it for backward compatibility
  * speed up initial device discard by procesing the ranges in order
  * disable block-grooup-tree feature if a dependent feature is explicitly
    unselected (like disabling no-holes), instead of erroring out
* check:
  * add ability to detect and fix missing orphan items in deleted subvolumes
  * add ability to fix inode refs from directory items
  * enhance detection on unknown inode keys
* libbtrfsutil:
  * minor version update to 1.4.0
  * add missing aliases for API updates done in 0.1.3, C and python
* libbtrfs:
  * patchlevel version update 0.1.5
  * error handling updates
* fixes:
  * with DUP profile and mixed sequential and conventional zoned make sure
    to track the right write pointers
  * scrub: fix ETA wraparound calculations, when many files get deleted
    during the operation bytes_scrubbed and bytes_total get too much out of
    sync, the ETA will be 0
* corrupt-block: add ability to specify key value when corrupting item keys
* experimental features:
  * initial remap tree support (new logical-to-logical mapping layer),
    coming in linux 7.0
* other:
  * documentation updates
  * CI updates, new and updated tests
  * code cleanups and refactoring
