On FreeBSD, if priorities divided by four (RQ_PPQ) are equal then
a difference between them is insignificant. In other words,
incrementing pri by only one as on Linux is insufficient.

Duplicate io and checksum ereport events can misrepresent that
things are worse than they seem. Ideally the zpool events and the
corresponding vdev stat error counts in a zpool status should be
for unique errors -- not the same error being counted over and over.
This can be demonstrated in a simple example. With a single bad
block in a datafile and just 5 reads of the file we end up with a
degraded vdev, even though there is only one unique error in the pool.
The proposed solution to the above issue, is to eliminate duplicates
when posting events and when updating vdev error stats. We now save
recent error events of interest when posting events so that we can
easily check for duplicates when posting an error.

If a `zfs_space_check_t` other than `ZFS_SPACE_CHECK_NONE` is used with
`dsl_sync_task_nowait()`, the sync task may fail due to ENOSPC.
However, there is no way to notice or communicate this failure, so it's
extremely difficult to use this functionality correctly, and in fact
almost all callers use `ZFS_SPACE_CHECK_NONE`.
This commit removes the `zfs_space_check_t` argument from
`dsl_sync_task_nowait()`, and always uses `ZFS_SPACE_CHECK_NONE`.

Allow to rename file systems without remounting if it is possible.
It is possible for file systems with 'mountpoint' property set to
'legacy' or 'none' - we don't have to change mount directory for them.
Currently such file systems are unmounted on rename and not even
mounted back.
This introduces layering violation, as we need to update
'f_mntfromname' field in statfs structure related to mountpoint (for
the dataset we are renaming and all its children).
In my opinion it is worth it, as it allow to update FreeBSD in even
cleaner way - in ZFS-only configuration root file system is ZFS file
system with 'mountpoint' property set to 'legacy'. If root dataset is
named system/rootfs, we can snapshot it (system/rootfs@upgrade), clone
it (system/oldrootfs), update FreeBSD and if it doesn't boot we can
boot back from system/oldrootfs and rename it back to system/rootfs
while it is mounted as /. Before it was not possible, because
unmounting / was not possible.

Commit dcdc12e added compatibility code to treat NR_SLAB_RECLAIMABLE_B
as if it were the same as NR_SLAB_RECLAIMABLE. However, the new value
is in bytes while the old value was in pages which means they are not
interchangeable.
The only place the reclaimable slab size is used is as a component of
the calculation done by arc_free_memory(). This function returns the
amount of memory the ARC considers to be free or reclaimable at little
cost. Rather than switch to a new interface to get this value it has
been removed it from the calculation. It is normally a minor component
compared to the number of inactive or free pages, and removing it
aligns the behavior with the FreeBSD version of arc_free_memory().

The root cause of the issue is that we only occasionally do as the
comments in the code suggest and actually ignore the %recv dataset when
it comes to filesystem limit tracking. Specifically, the only time we
ignore it is when initializing the filesystem and snapshot limit values;
when creating a new %recv dataset or deleting one, we always update
the bookkeeping. This causes a problem if you init the fs count on a
filesystem that already has a %recv dataset, since the bookmarking
will be decremented but not incremented. This is resolved in this
patch by simply always tracking the %recv dataset as a child.
