Merge libzfs_core branch: includes MFV 238590, 238592, 247580
MFV 238590, 238592: In the first zfs ioctl restructuring phase, the libzfs_core library was introduced. It is a new thin library that wraps around kernel ioctl's. The idea is to provide a forward-compatible way of dealing with new features. Arguments are passed in nvlists and not random zfs_cmd fields, new-style ioctls are logged to pool history using a new method of history logging.
http://blog.delphix.com/matt/2012/01/17/the-future-of-libzfs/
MFV 247580 [1]: To address issues of several deadlocks and race conditions the locking code around dsl_dataset was rewritten and the interface to synctasks was changed.
User-Visible Changes: "zfs snapshot" can create more arbitrary snapshots at once (atomically) "zfs destroy" destroys multiple snapshots at once "zfs recv" has improved performance
Backward Compatibility: I have extended the compatibility layer to support full backward compatibility by remapping or rewriting the responsible ioctl arguments. Old utilities are fully supported by the new kernel module.
Forward Compatibility: New utilities work with old kernels with the following restrictions: - creating, destroying, holding and releasing of multiple snapshots at once is not supported, this includes recursive (-r) commands
Illumos ZFS issues: 2882 implement libzfs_core 2900 "zfs snapshot" should be able to create multiple, arbitrary snapshots at once 3464 zfs synctask code needs restructuring

Finally... Import the latest open-source ZFS version - (SPA) 28.
Few new things available from now on:
- Data deduplication. - Triple parity RAIDZ (RAIDZ3). - zfs diff. - zpool split. - Snapshot holds. - zpool import -F. Allows to rewind corrupted pool to earlier transaction group. - Possibility to import pool in read-only mode.

Update ZFS from version 6 to 13 and bring some FreeBSD-specific changes.
This bring huge amount of changes, I'll enumerate only user-visible changes:
- Delegated Administration
Allows regular users to perform ZFS operations, like file system creation, snapshot creation, etc.
- L2ARC
Level 2 cache for ZFS - allows to use additional disks for cache. Huge performance improvements mostly for random read of mostly static content.
- slog
Allow to use additional disks for ZFS Intent Log to speed up operations like fsync(2).
- vfs.zfs.super_owner
Allows regular users to perform privileged operations on files stored on ZFS file systems owned by him. Very careful with this one.
- chflags(2)
Not all the flags are supported. This still needs work.
- ZFSBoot
Support to boot off of ZFS pool. Not finished, AFAIK.

- Snapshot properties
- New failure modes
Before if write requested failed, system paniced. Now one can select from one of three failure modes: - panic - panic on write error - wait - wait for disk to reappear - continue - serve read requests if possible, block write requests
- Refquota, refreservation properties
Just quota and reservation properties, but don't count space consumed by children file systems, clones and snapshots.
- Sparse volumes
ZVOLs that don't reserve space in the pool.
- External attributes
Compatible with extattr(2).
- NFSv4-ACLs
Not sure about the status, might not be complete yet.
Submitted by: trasz
- Creation-time properties
- Regression tests for zpool(8) command.

Please welcome ZFS - The last word in file systems.
ZFS file system was ported from OpenSolaris operating system. The code in under CDDL license.
I'd like to thank all SUN developers that created this great piece of software.
