This is the result after running 'clang-format -i' on all C++ files and
headers, with the defined formatting rules in .clang-format.
Only the openvpn/common/unicode-impl.hpp has been excluded, as that is
mostly a copy of an external project.

Since IPv4/IPv6 should be treated equally, we should have also
the opportunity to block IPv4. With this change we follow the API
that also Android provides and expliticly tell tunbuilder what to
do with address families that are not used by the VPN. If a
address family is used by the VPN, nothing changes.
This also remove IV_IPV6 as it is not used.
