MFC r251629: 3741 zfs needs better comments
Embellish the comments in various components of ZFS. Move some comments around closer to what they describe. Specifically, answer the questions:
- What are some of the edge cases of the dbuf state machine? - What does a txg quiesce do? - When does the DMU notify threads waiting on txg's that they may proceed? - How do the calculations for RAIDZ map allocations work? - What process do the RAIDZ I/O start and done callbacks follow?
While here, adjust the function prototype of dmu_zfetch.c:dmu_zfetch_colinear() to match its comment which describes its return as a boolean.

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.

As far as I can tell systems that have less than 4GB are more often hurt by prefetched than helped. On i386 systems and systems with less than 4GB, prefetch is now disabled by default. I've added a prefetch enable tunable, to enable prefetching for those systems. The prefetch disable tunable will continue to unconditionally disable prefetching.

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.
Submitted by: dfr
- 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.
