Add the 'zfs version' and 'zpool version' subcommands to display
the version of the user space utilities and loaded zfs kernel
module. For example:
$ zfs version
zfs-0.8.0-rc3_169_g67e0366b88
zfs-kmod-0.8.0-rc3_169_g67e0366b88
The '-V' and '--version' aliases were added to support the
common convention of using 'zfs --version` to obtain the version
information.

zfs.8 correctly said that GRUB did not support them, but
zpool-features.5 said that "Booting off pools...is supported." Now,
zpool-features.5 discusses GRUB specifically and indicates its lack of
support for these features. Also, I have clarified the wording in both
places to indicate that the pool feature cannot be used. It's not a
filesystem dataset thing, but pool-wide.
I described this as "cannot be used". I think technically the feature
can be enabled, just not active. However, the effect is essentially the
same: you cannot enable those checksum algorithms on any dataset in the
pool, so you might as well not enable the feature (which is just
pointing a loaded gun at your foot). In the past, an argument could be
made that having all the features enabled was useful for simplicity, as
long as you didn't activate the GRUB-incompatible features, but that's
getting less and less realistic over time. A user can still do that,
but we should not encourage that.

When a pool is initially created (by `zpool create`), predictive
prefetch is inadvertently disabled, until the pool is export/import-ed,
or the machine is rebooted.
When device removal was introduced, we added some code to disable
predictive prefetching until indirect vdevs have been loaded. This
resulted in the "default state" of prefetch being disabled, until we
proactively enable it after indirect vdevs are loaded. Unfortunately
this resulted in a few bugs where in some code paths we neglect to
enable predictive prefetch. The first of these was fixed by
20507534d4
This commit fixes another case where we also need to explicitly enable
predictive prefetch, when the pool is initially created.

UNMAP/TRIM support is a frequently-requested feature to help
prevent performance from degrading on SSDs and on various other
SAN-like storage back-ends. By issuing UNMAP/TRIM commands for
sectors which are no longer allocated the underlying device can
often more efficiently manage itself.
This TRIM implementation is modeled on the `zpool initialize`
feature which writes a pattern to all unallocated space in the
pool. The new `zpool trim` command uses the same vdev_xlate()
code to calculate what sectors are unallocated, the same per-
vdev TRIM thread model and locking, and the same basic CLI for
a consistent user experience. The core difference is that
instead of writing a pattern it will issue UNMAP/TRIM commands
for those extents.
The zio pipeline was updated to accommodate this by adding a new
ZIO_TYPE_TRIM type and associated spa taskq. This new type makes
is straight forward to add the platform specific TRIM/UNMAP calls
to vdev_disk.c and vdev_file.c. These new ZIO_TYPE_TRIM zios are
handled largely the same way as ZIO_TYPE_READs or ZIO_TYPE_WRITEs.
This makes it possible to largely avoid changing the pipieline,
one exception is that TRIM zio's may exceed the 16M block size
limit since they contain no data.
In addition to the manual `zpool trim` command, a background
automatic TRIM was added and is controlled by the 'autotrim'
property. It relies on the exact same infrastructure as the
manual TRIM. However, instead of relying on the extents in a
metaslab's ms_allocatable range tree, a ms_trim tree is kept
per metaslab. When 'autotrim=on', ranges added back to the
ms_allocatable tree are also added to the ms_free tree. The
ms_free tree is then periodically consumed by an autotrim
thread which systematically walks a top level vdev's metaslabs.
Since the automatic TRIM will skip ranges it considers too small
there is value in occasionally running a full `zpool trim`. This
may occur when the freed blocks are small and not enough time
was allowed to aggregate them. An automatic TRIM and a manual
`zpool trim` may be run concurrently, in which case the automatic
TRIM will yield to the manual TRIM.

This patch fixes a few issues with raw receives involving

* dnode_reallocate() now calls dnode_set_blksz() instead of
dnode_setdblksz(). This ensures that any remaining dbufs with
blkid 0 are resized along with their containing dnode upon
reallocation.
* One of the calls to dmu_free_long_range() in receive_object()
needs to check that the object it is about to free some contents
or hasn't been completely removed already by a previous call to
dmu_free_long_object() in the same function.
* The same call to dmu_free_long_range() in the previous point
needs to ensure it uses the object's current block size and
not the new block size. This ensures the blocks of the object
that are supposed to be freed are completely removed and not
simply partially zeroed out.
This patch also adds handling for DRR_OBJECT_RANGE records to
dprintf_drr() for debugging purposes.
