This is a preliminary fstests side of the btrfs encryption feature;
more tests are needed, but this gets the existing encryption tests
working with btrfs. This requires the latest related progs and kernel
changesets.

Marked as RFC because they're not ready to merge until all its
dependencies finish landing; this is primarily to demonstrate that
extent encryption, between fscrypt and btrfs, does not significantly
change user-visible behavior.

Changelog:

RFC v2:
- Reverted changes to generic/580 and generic/595 to match the new
  'soft-delete' behavior introduced in v2 of kernel patchset
  "fscrypt: add extent encryption". (change 6)
- Removed extraneous syncs/drop_caches and added copyright to new test
  (change 8), as per Filipe's comments.

RFC v1:
- https://lore.kernel.org/linux-btrfs/cover.1688076612.git.sweettea-kernel@dorminy.me/T/#t

Sweet Tea Dorminy (8):
  common/encrypt: separate data and inode nonces
  common/encrypt: add btrfs to get_encryption_*nonce
  common/encrypt: add btrfs to get_ciphertext_filename
  common/encrypt: enable making a encrypted btrfs filesystem
  generic/613: write some actual data for btrfs
  tests: adjust generic/429 for extent encryption
  common/verity: explicitly don't allow btrfs encryption
  btrfs: add simple test of reflink of encrypted data
