6c407ae27b wg-quick: add intentionally undocumented userspace implementation knob 
This knob might disappear at some point, and we don't want to encourage
its use, so it's not being documented, but this should help with
development of new implementations.

81879fe346 wg-quick: account for specified fwmark in auto routing mode 
If we're doing automatic routing with default routes, but the config has
also specified an explicit fwmark, then use that explicit fwmark, even
if it's conflicting, since the administrator has explicitly opted into
using it. Also, when shutting down the interface, we only now remove the
fancy rules if we're in automatic routing mode with default routes.

99264cb88f wg-quick: if resolvconf/interface-order exists, use it 
Some older broken resolvconf implementations ignore -m, but do have an
interface-order list. It's better to use this list dynamically, in case
it changes, or in case it's not used by the OS's resolvconf
implementation, such as in the case of systemd or openresolv.

For now, it's faster:

hacl64: 109782 cycles per call

It's quite possible this commit will be reverted with nice changes from
INRIA, though.
