cb83a26c90 replication: wakeup + retry handling: make wakeups work in retry wait states
- handle wakeups in Planning state
- fsrep.Replication yields immediately in RetryWait
- once the queue only contains fsrep.Replication in retryWait:
transition replication.Replication into WorkingWait state
- handle wakeups in WorkingWait state, too

975fdee217 replication & pruning: ditch replicated-property, use bookmark as cursor instead
A bookmark with a well-known name is used to track which version was
last successfully received by the receiver.
The createtxg that can be retrieved from the bookmark using `zfs get` is
used to set the Replicated attribute of each snap on the sender:
If the snap's CreateTXG > the cursor's, it is not yet replicated,
otherwise it has been.

There is an optional config option to change the behvior to
`CreateTXG >= the cursor's`, and the implementation defaults to that.

The reason: While things work just fine with `CreateTXG > the cursor's`,
ZFS does not provide size estimates in a `zfs send` dry run
(see acd2418).
However, to enable the use case of keeping the snapshot only around for
the replication, the config flag exists.
