Fabian Grünbichler 8d688ce66a Skip FREEOBJECTS for objects which can't exist
When sending an incremental stream based on a snapshot, the receiving
side must have the same base snapshot.  Thus we do not need to send
FREEOBJECTS records for any objects past the maximum one which exists
locally.

This allows us to send incremental streams (again) to older ZFS
implementations (e.g. ZoL < 0.7) which actually try to free all objects
in a FREEOBJECTS record, instead of bailing out early.

ZFS is an advanced file system and volume manager which was originally developed for Solaris and is now maintained by the Illumos community.

ZFS on Linux, which is also known as ZoL, is currently feature complete. It includes fully functional and stable SPA, DMU, ZVOL, and ZPL layers. And it's native!
