eCryptfs updates for 7.3-rc1

The set of eCryptfs changes for the 7.3-rc1 merge window consists of:
- Hardening and fixes for maliciously crafted eCryptfs metadata in the
  lower encrypted file
- Hardening and fixes for maliciously crafted userspace <-> kernel
  miscdev communications
- Locking fixes for userspace <-> kernel miscdev communications
- Fix to display encrypted filename related mount options
- Clean up address_space_operations and reduce build dependencies by
  moving to filemap_dirty_folio()
- Get rid of an unnecessary memory allocation in the inode update path
- Kernel-doc formatting corrections

The patches have all spent time in linux-next and they pass all tests in
the ecryptfs-utils tree. I did manual validation of the miscdev fixes
since we don't have test coverage for that feature.
