Supporting VLAN for Mac OS X using TunTapOSX

In Linux, SoftEther can make virtual NICs using TUN/TAP, and it cannot in OS X. I have wanted to use virtual NICs with TunTapOSX which is the most famous TUN/TAP implementation for OS X (http://tuntaposx.sourceforge.net/).

So I have written a patch implementing virtual NICs based on TunTapOSX. After configure-ing, you can command "make NO_VLAN=" and build the SoftEther software using TunTapOSX.
