OpenZFS commit: 2e2a46e0a597b3ee606ea7dc5bc527459077322f

Remove $FreeBSD$: one-line sh pattern

Remove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/

cddl/*: add a WITH(OUT)_DTRACE option

Add an option to enable/disable DTrace without disabling ZFS. New
architectures such as CHERI may support ZFS before they support DTrace
and the old model of WITHOUT_CDDL disabling both wasn't helpful.

For compatiblity, the CDDL option remains and WITHOUT_CDDL implies
WITHOUT_DTRACE. WITHOUT_DTRACE also implies WITHOUT_CTF.

As part of this change, largely convert cddl/*/Makefile to using the
more compact SUBDIR.${MK_<FOO>}+= form rather than using intermediate
variables.

zfs: attach zpool_influxdb to build

From the zpool_influxdb.8 manual page:
zpool_influxdb produces InfluxDB-line-protocol-compatible metrics from
zpools. Like the zpool command, zpool_influxdb reads the current pool
status and statistics. Unlike the zpool command which is intended for
humans, zpool_influxdb formats the output in the InfluxDB line protocol.
The expected use is as a plugin to a metrics collector or aggregator,
such as Telegraf.

zpool_influxdb is installed into /usr/libexec/zfs/
