This causes wg-quick up to wait for the monitor to exit before it exits,
so that launchd can correctly wait on it.

`wg-quick strip` prints the config file to stdout after stripping it of
all wg-quick-specific options.
This enables tricks such as `wg addconf $DEV <(wg-quick strip $DEV)`.

Apparently Haiku has a misbehaving /dev/urandom.
While we're at it, simplify the function signature to completely succeed
or completely fail and make sure the caller checks the result.

The commit 7c833642 ("wg-quick: freebsd: allow loopback to work") was
supposed to make things better, but actually it just started sending
legitimate localhost traffic over the WireGuard interface, which is
really quite bad.
This reverts commit 7c833642dfa342218602ab18e7091e86408d2982.

Since wg-quick(8) calls wg(8) which does hostname lookups, we should
probably only run this after we're allowed to look up hostnames.

FreeBSD adds a route for point-to-point destination addresses. We don't
really want to specify any destination address, but unfortunately we
have to. Before we tried to cheat by giving our own address as the
destination, but this had the unfortunate effect of preventing
loopback from working on our local ip address. We work around this with
yet another kludge: we set the destination address to 127.0.0.1. Since
127.0.0.1 is already assigned to an interface, this has the same effect
of not specifying a destination address, and therefore we accomplish the
intended behavior.

Netlink returns NLM_F_DUMP_INTR if the set of all tunnels changed
during the dump. That's unfortunate, but is pretty common on busy
systems that are adding and removing tunnels all the time. Rather
than retrying, potentially indefinitely, we just work with the
partial results.

This is not useful for WireGuard, but for the general use case we

The only things wg-quick(8) needs from Homebrew are bash(1) and wg(8).
Other than that, it's explicitly coded against the native system
utilities. Since wg-quick(8) and bash(1) are invoked in auto_su by their
full absolute path (via $SELF and $BASH, respectively), we can simply
set the $PATH to be prefixed by the default system binary paths. This
way, if users install tools that conflict with system tools -- such as
GNU coreutils -- we won't accidently call those.
