Add 'zfs wait' command Add a mechanism to wait for delete queue to drain. When doing redacted send/recv, many workflows involve deleting files that contain sensitive data. Because of the way zfs handles file deletions, snapshots taken quickly after a rm operation can sometimes still contain the file in question, especially if the file is very large. This can result in issues for redacted send/recv users who expect the deleted files to be redacted in the send streams, and not appear in their clones. This change duplicates much of the zpool wait related logic into a zfs wait command, which can be used to wait until the internal deleteq has been drained. Additional wait activities may be added in the future.

.Dt ZFS-WAIT 8
Remove hard coded "Linux" OS from manpages The recommended practice for `.Os` on FreeBSD is to not specify any arguments. The correct OS name is used automatically. Oddly enough, on the Linux distro I tested this on (CentOS 7), the man pager defaulted to displaying "BSD" as the OS rather than "Linux". To accommodate this, tack " Linux" back on in an install hook on Linux. This is much simpler than removing it for FreeBSD when vendored in the base system.

Waits until all background activity of the given types has ceased in the given
filesystem.
The activity could cease because it has completed or because the filesystem has
been destroyed or unmounted.
If no activities are specified, the command waits until background activity of
every type listed below has ceased.
If there is no activity of the given types in progress, the command returns
immediately.
