Commit 089aec00b pulled in a dependency for a very server specific
feature not normally needed in more basic implementations. This
resulted in the code not being able to compile unless the advanced
implementation would be available. This only happens when ENABLE_DCO is
enabled.

That API was introduced in commit 5c00943
to implement persistence for macOS. That functionality
was refactored in 0609c76, but framework was left intact.
Since socket_protect() is called almost at the
same time as ip_hole_punch() and also receives
remote address, there is no need in this unused
API anymore.

There are two ways how Linux tun can be manipulated -
by using iproute2 or netlink. Both implementations have
defined identical Setup class implementation.
This commit factors out Setup class from tun implementations
and templatizes it, which removes need in duplicated code.

When ASIO performs an async DNS resolution, it relies on the
getaddrinfo() syscall in order to obtain a result.
This syscall is non-interruptible by design, which means that, in case
of sudden stop command received by the user, the core will not be able
to terminate all its threads until the getaddrinfo() has returned
(either by timeout or with a result).
If the the external core user is synchronously waiting for it to
terminate (i.e. like a UI), this behaviour will lead to the entire
client hanging.
To avoid this issue, this commit converts each asynchronous DNS
resolution to a synchrnous one performed in a detached thread.
This way, if the core wants to stop, it can do so without waiting for
the DNS thread to join. Otherwise, this change should not lead to any
functional difference.
