Ryan Moeller 825d8e1b0f FreeBSD: Fix memory leaks in kstats
Don't handle (incorrectly) kmem_zalloc() failure.  With KM_SLEEP,
will never return NULL.

Free the data allocated for non-virtual kstats when deleting the object.

Ryan Moeller 0dc6fb730f FreeBSD: Skip RAW kstat sysctls by default
These kstats are often expensive to compute so we want to avoid them
unless specifically requested.

The following kstats are affected by this change:

kstat.zfs.${pool}.multihost
kstat.zfs.${pool}.misc.state
kstat.zfs.${pool}.txgs
kstat.zfs.misc.fletcher_4_bench
kstat.zfs.misc.vdev_raidz_bench
kstat.zfs.misc.dbufs
kstat.zfs.misc.dbgmsg

In FreeBSD 13, sysctl(8) has been updated to still list the
names/description/type of skipped sysctls so they are still
discoverable.

Ryan Moeller 25e44a17ff Make dbufstat work on FreeBSD
With procfs_list kstats implemented for FreeBSD, dbufs are now exposed
as kstat.zfs.misc.dbufs.

On FreeBSD, dbufstats can use the sysctl instead of procfs when no
input file has been given.

Enable the dbufstats tests on FreeBSD.

Matthew Macy c70c6e004e FreeBSD: Add support for procfs_list
The procfs_list interface is required by several kstats. Implement
this functionality for FreeBSD to provide access to these kstats.

Mark Johnston aba5b019cb Annontate FreeBSD sysctls with CTLFLAG_MPSAFE
Without this, the sysctl system calls will acquire a global lock before
invoking the handler.  This is noticeable in some situations when
running top(1).  The global lock is mostly vestigal but continues to see
some use and so contention is still a problem; until the default sense
of the MPSAFE flag changes, we have to annotate each and every handler.

Matthew Macy ecd3976f5b FreeBSD: Fix up after spa_stats.c move
Moving spa_stats added the additional burden of supporting
KSTAT_TYPE_IO.

spa_state_addr will always return a valid value regardless of
the value of 'n'. On FreeBSD this will cause an infinite loop
as it relies on the raw ops addr routine to indicate that there
is no more data.

Add FreeBSD support to OpenZFS
Add the FreeBSD platform code to the OpenZFS repository.  As of this
commit the source can be compiled and tested on FreeBSD 11 and 12.
Subsequent commits are now required to compile on FreeBSD and Linux.
Additionally, they must pass the ZFS Test Suite on FreeBSD which is
being run by the CI.  As of this commit 1230 tests pass on FreeBSD
and there are no unexpected failures.
