return -1, set buf->len to 0 rather than -1. While downstream
code is set up to consider the buffer invalidated if its length
is <= 0, this change makes the code cleaner and safer.

by allowing openvpn --mktun to be used with --user and --group
to set the UID/GID of the tun device node. Also added --iproute

Implemented AUTO_USERID using
MD5(MAC address(primary network adapter)).
Currently implemented for Linux and Windows.
Basically if ENABLE_AUTO_USERID is defined,
the --auth-user-pass option will not prompt
for username/password, but will rather generate
a unique username and blank password.
