MFC r305323: MFV r302991: 6950 ARC should cache compressed data
illumos/illumos-gate@dcbf3bd6a1f1360fc1afcee9e22c6dcff7844bf2 https://github.com/illumos/illumos-gate/commit/dcbf3bd6a1f1360fc1afcee9e22c6dcff 7844bf2
https://www.illumos.org/issues/6950 When reading compressed data from disk, the ARC should keep the compressed block cached and only decompress it when consumers access the block. The uncompressed data should be short-lived allowing the ARC to cache a much large r amount of data. The DMU would also maintain a smaller cache of uncompressed blocks to minimize the impact of decompressing frequently accessed blocks.

MFC r289422: 4185 add new cryptographic checksums to ZFS: SHA-512, Skein, Edon-R

This is only a partial merge of respective ZFS infrastructure changes. At this moment FreeBSD kernel has no those crypto algorithms, so the parts of the code to enable them are commented out. When they are implemented, it will be trivial to plug them in.

MFC r286705: 5960 zfs recv should prefetch indirect blocks 5925 zfs receive -o origin=
Reviewed by: Prakash Surya <prakash.surya@delphix.com> Reviewed by: Matthew Ahrens <mahrens@delphix.com> Author: Paul Dagnelie <pcd@delphix.com>
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.
