This commit adds the --saved (-S) to the 'zfs send' command. This flag allows a user to send a partially received dataset, which can be useful when migrating a backup server to new hardware. This flag is compatible with resumable receives, so even if the saved send is interrupted, it can be resumed. The flag does not require any user / kernel ABI changes or any new feature flags in the send stream format.
