Implement bookmark copying
This feature allows copying existing bookmarks using
zfs bookmark fs#target fs#newbookmark
There are some niche use cases for such functionality,
e.g. when using bookmarks as markers for replication progress.
Copying redaction bookmarks produces a normal bookmark that
cannot be used for redacted send (we are not duplicating
the redaction object).
ZCP support for bookmarking (both creation and copying) will be
implemented in a separate patch based on this work.
Overview:
- Terminology:
- source = existing snapshot or bookmark
- new/bmark = new bookmark
- Implement bookmark copying in `dsl_bookmark.c`
- create new bookmark node
- copy source's `zbn_phys` to new's `zbn_phys`
- zero-out redaction object id in copy
- Extend existing bookmark ioctl nvlist schema to accept
bookmarks as sources
- => `dsl_bookmark_create_nvl_validate` is authoritative
- use `dsl_dataset_is_before` check for both snapshot
and bookmark sources
- Adjust CLI
- refactor shortname expansion logic in `zfs_do_bookmark`
- Update man pages
- warn about redaction bookmark handling
- Add test cases
- CLI
- pyyzfs libzfs_core bindings
