Add support of utun devices under Mac OS X
Mac OS X 10.7+ natively supports tun devices (called utun). The "standard"
utun.ko driver is sometimes problematic (e.g. VmWare Fusion 5 and tun.ko
do not work together).
When OpenVPN is compiled with utun support it will if no dev-node is given
first try to use utun and if that is not available will try the
traditional tun devices
v2: Fixed tap support, get device name via ioctl, add manage
v3.1: Fix compiling without if/utun.h, fix manage errors
v4/v5: Don't try open to dynamically open utun0 -255 when early utun
initialization fails, fix fallback to tun, give fatal error message when
utun fails but no tun fallback should be done
v6: add commit message change log, replace strstr with strncmp, move
v7: Throw error if a user does the strange combination of --dev tun
--dev-type tap and --dev-node utun
A lot good input on earlier patches by Jonathan K. Bullard
