Xin LI 8bcd603968 MFV r274273: 
ZFS large block support.

Please note that booting from datasets that have recordsize greater
than 128KB is not supported (but it's Okay to enable the feature on
the pool).  This *may* remain unchanged because of memory constraint.

Limited safety belt is provided for mounted root filesystem but use
caution is advised.

Illumos issue:
    5027 zfs large block support

README 

$FreeBSD$

This directory contains various files derived from CDDL sources that
are used by the ZFS bootstrap:

    fletcher.c			checksum support
    sha256.c			checksum support
    lz4.c			compression support
    lzjb.c			compression support
    blkptr.c			ZFS embedded-data block pointers support
    zfssubr.c			checksum, compression and raidz support
    zfsimpl.h			mostly describing the physical layout

The files fletcher.c, lzjb.c, lz4.c, sha256.c and blkptr.c are largely identical
to the ZFS base code (with write support removed) and could be shared but that
might complicate future imports from Illumos.
