Otherwise nft(8) has strange ideas of what a string is.

We used to reach back into parent directories for this, but with the
repo split, we now require our own copy.
We use -idirafter in case system headers are installed for the
wireguard.h netlink definitions.

The ADDRESSES array might not have addresses added during PreUp. But
moreover, nft(8) and iptables(8) don't like ip addresses in the form
somev6prefix::someipv4suffix, such as fd00::1.2.3.4, while ip(8) can
handle it. So by adding these first and then asking for them back, we
always get normalized addresses suitable for nft(8) and iptables(8).

Daniel argues that technically a package manager could install nft(8)
after previously having started wg-quick(8) using iptables(8).

Older nft(8), such as that on Ubuntu, does not accept the - parameter to
the -f argument and doesn't accept symbolic priority names. So instead
use the canonical numeric priority forms and use <(echo) instead of -.

If nft(8) is installed, use it. These rules should be identical to the
iptables-restore(8) ones, with the advantage that cleanup is easy
because we use custom table names.

systemd-resolved has a compatibility interface for use with resolvconf
scripts when resolvectl is called from a symlink from resolvconf.
However, when tearing down the interface, cmd_down calls del_if and then
unset_dns. In the case of systemd-resolved, deleting the interface also
removes the systemd-resolved entry and causes resolvconf -d to fail when
resolvconf really is a symlink to resolvectl. This causes `wg-quick
down` and 'wg-quick@.service' to exit with failure.
Instead we use the resolvconf '-f' flag to ignore non-existent
interfaces, supported by both openresolv and sd-resolved resolvconf.

route(8) has always used the `-T` option to specify the
routing table; there is no `rdomain` option.

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.
