MFC r289362, r289445: 2605 want to resume interrupted zfs send

For more info, see: - slides http://www.slideshare.net/MatthewAhrens/openzfs-send-and-receive - video https://www.youtube.com/watch?v=iY44jPMvxog - manpage changes (for zfs resume -s and zfs send -t) - upcoming talk at the OpenZFS Developer Summit
The TL;DR is: Use "zfs receive -s" to save the partially received state on failure. On failure, get the receive token with "zfs get receive_resume_token <fs>" Resume the send with "zfs send -t <token_value>"

ZFS expects a copyout of zfs_cmd_t on an ioctl error. Our sys_ioctl() doesn't copyout in this case.
To solve this issue a new struct zfs_iocparm_t is introduced consisting of: - zfs_ioctl_version (future backwards compatibility purposes) - user space pointer to zfs_cmd_t (copyin and copyout) - size of zfs_cmd_t (verification purposes)
The copyin and copyout of zfs_cmd_t is now done the illumos (vendor) way what makes porting of new changes easier and ensures correct behavior if returning an error.

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

Fix the zfs_ioctl compat layer to support zfs_cmd size change introduced in r247265 (ZFS deadman thread). Both new utilities now support the old kernel and new kernel properly detects old utilities.
For future backwards compatibility, the vfs.zfs.version.ioctl read-only sysctl has been introduced. With this sysctl zfs utilities will be able to detect the ioctl interface version of the currently loaded zfs module.
As a side effect, the zfs utilities between r247265 and this revision don't support the old kernel module. If you are using HEAD newer or equal than r247265, install the new kernel module (or whole kernel) first.

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.
