Brian Behlendorf 43e52eddb1 Implement zfs_ioc_recv_new() for OpenZFS 2605
Adds ZFS_IOC_RECV_NEW for resumable streams and preserves the legacy
ZFS_IOC_RECV user/kernel interface.  The new interface supports all
stream options but is currently only used for resumable streams.
This way updated user space utilities will interoperate with older
kernel modules.

ZFS_IOC_RECV_NEW is modeled after the existing ZFS_IOC_SEND_NEW
handler.  Non-Linux OpenZFS platforms have opted to change the
legacy interface in an incompatible fashion instead of adding a
new ioctl.
