Before this PR, we would panic in the `check` phase of `endpoint.Send()`'s `TryBatchDestroy` call in the following cases: the current protection strategy does NOT produce a tentative replication cursor AND * `FromVersion` is a tentative cursor bookmark * `FromVersion` is a snapshot, and there exists a tentative cursor bookmark for that snapshot * `FromVersion` is a bookmark != tentative cursor bookmark, but there exists a tentative cursor bookmark for the same snapshot as the `FromVersion` bookmark In those cases, the `check` concluded that we would delete `FromVersion`. It came to that conclusion because the tentative cursor isn't part of `obsoleteAbs` if the protection strategy doesn't produce a tentative replication cursor. The scenarios above can happen if the user changes the protection strategy from "with tentative cursor" to one "without tentative replication cursor", while there is a tentative replication cursor on disk. The workaround was to rename the tentative cursor. In all cases above, `TryBatchDestroy` would have destroyed the tentative cursor. In case 1, that would fail the `Send` step and potentially break replication if the cursor is the last common bookmark. The `check` conclusion was correct. In cases 2 and 3, deleting the tentative cursor would have been fine because `FromVersion` was a different entity than the tentative cursor. So, destroying the tentative cursor would be the right call. The solution in this PR is as follows: * add the `FromVersion` to the `liveAbs` set of live abstractions * rewrite the `check` closure to use the full dataset path (`fullpath`) to identify the concrete ZFS object instead of the `zfs.FilesystemVersionEqualIdentity`, which is only identified by matching GUID. * Holds have no dataset path and are not the `FromVersion` in any case, so disregard them. fixes #666
