MFV r286704: 5960 zfs recv should prefetch indirect blocks
5925 zfs receive -o origin=

While running 'zfs recv' we noticed that every 128th 8K block required a
read. We were seeing that restore_write() was calling dmu_tx_hold_write()
and the indirect block was not cached. We should prefetch upcoming indirect
blocks to avoid having to go to disk and blocking the restore_write().
Allow an incremental send stream to be received as a clone, even if the
stream does not mark it as a clone.
