implementing some of them using existing ones.
- Allow to compile ZFS on all archs and use atomic operations surrounded
by global mutex on archs we don't have or can't have all atomic
operations needed by ZFS.

FreeBSD's namecache works quite well with ZFS, so remove DNLC.

MFp4: Now that ZFS can use FreeBSD's namecache, turn it off by default and
turn off DNLC, but don't remove DNLC yet just in case.

MFp4: Synchronize with recent OpenSolaris changes.

Move atomic.S files to directories that better fit OpenSolaris directory
layout.

Add Makefile for zfs.ko kernel module.

make UMA the default allocator for ZFS buffers - this avoids
a great deal of contention in kmem_alloc

MFp4 changes neccessary for NFSv4 ACLs support in ZFS. This is mostly
about removing a few #ifdefs and providing compatibility wrappers and
VOP implementations to get and set an ACL; ZFS does ACL enforcement all
by itself.

Note that the VOPs are ifdefed out for now, so this change should be
a no-op.

rename xdr support files to avoid conflicts when linking in to the kernel

fix atomic.S rename and vimage breakage

The latter was pointed out by Artem Belevich

- rename atomic.S and crc32.c to avoid collisions when linking zfs in to the kernel

- ifdef out acl_{alloc, free}, they aren't used by zfs and conflict with existing in-kernel routi

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.

- Creation-time properties

- Regression tests for zpool(8) command.
