Jason A. Donenfeld bfb31ac953 Makefile: remove pwd from compile output
We previously included $(pwd) in the compile output pretty printer,
because it matched our parent out-of-tree module build. Since we're no
longer coupled to the module, we can return to a prettier scheme of just
using the object name.

Jason A. Donenfeld 2f74ac29cf wg: add back source formerly shared with kernel module
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.

Jason A. Donenfeld 6262906e5c wg-quick: linux: use already configured addresses instead of in-memory
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).

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.

Ronan Pigott 4154476d89 wg-quick: linux: don't fail down when using systemd-resolved
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.
