Jason A. Donenfeld 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.

Jason A. Donenfeld 4502350512 wg-quick: darwin: use bash from environment and require bash 4+
For properly configured Homebrew installations /usr/local/bin should be

used in more than one setting.

Jason A. Donenfeld 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.

Jason A. Donenfeld 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.

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

Greg Kroah-Hartman 01d00bc035 global: add SPDX tags to all files
It's good to have SPDX identifiers in all files as the Linux kernel
developers are working to add these identifiers to all files.

Update all files with the correct SPDX license identifier based on the license
text of the project or based on the license in the file itself.  The SPDX
identifier is a legally binding shorthand, which can be used instead of the
full boiler plate text.
