Jason A. Donenfeld 9ef84af8c0 wg: use key_is_zero for comparing to zeros
Maybe an attacker on the system could use the infoleak in /proc to gauge
how long a wg(8) process takes to complete and determine the number of
leading zeros. This is somewhat ridiculous, but it's possible somebody
somewhere might at somepoint care in the future, so alright.

Jason A. Donenfeld 11204afd6f wg-quick: do not set explicit src route for v6 default route
This was only required because clueless network operators were trying to
route fec0::/10 globally, when that range doesn't actually have global
scope. Now that we understand the cause was operator error, we revert
the change here, so that the routing table is kept consistent.

This reverts commit 64e47de870a2f0575b5564a70e5680b48ab83ff9.

Jason A. Donenfeld f65fba7dd8 man: update wg-quick(8) to show Debian resolvconf braindamage
While OpenResolv supports explicit ordering directives such as `-m` and
exclusivity directives such as `-x`, Debian's own resolvconf supports
none of this, instead using a hard coded list of interface name
templates for determining ordering. While trying to emulate `-x` is
difficult [*], we can at least try to mostly emulate `-m 0` by
masquerading as a `tun*` interface to resolvconf. Ugly, but it works.

[*] One heavy handed way of emulating `-x` would be something like:

   # echo nameserver 8.8.8.8 > /etc/resolv.conf.wg0-exclusive
   # mount --bind -o ro /etc/resolv.conf.wg0-exclusive /etc/resolv.conf
   # rm -f /etc/resolv.conf.wg0-exclusive

This in practice works quite well, but is a bit heavy to put in a man
page. It also doesn't "stack" well. For example, if we simply run
`umount /etc/resolv.conf`, how do we know which resolv.conf entry we're
unmounting?
