Lev Stipakov 8593c41540 ovpn-dco: basic communication with kernel module
Add dependency to libnl-genl, which is C library
for generic netlink communication.

Implement C++ wrapper for libnl-genl, inspired by
ovpn-cli - a test client for ovpn-dco kernel module.

Implement ovpn-dco netlink commands:

  - OVPN_CMD_START_VPN - pass transport socket,
protocol (UDP) and mode (client).

  - OVPN_CMD_NEW_PEER - pass local and remote
endpoint info.

  - OVPN_CMD_PACKET - move (control channel) packets
between userspace and kernel.

  - OVPN_CMD_DEL_PEER - sent by kernel when peer is deleted
due to keepalive timeout (causes reconnect) or any other
reason (considered as fatal).

This change allows to perform openvpn handshake and
establish connection which doesn't work, since data channel
keys are not passed to kernel yet.
