This is a trivial port to netdev-bsd of Justin Pettit's netdev-linux
commit 33d82a56d (netdev-linux: Use underlying tap device on
netdev_linux_listen().), which had the commit message:
Commit acf608 (ofproto-dpif: Use a single underlying datapath across
multiple bridges.) broke connectivity to userspace datapath devices. The
code assumed the first caller to open a tap device with
netdev_linux_open() wanted to write to it. This commit moves that logic
to when netdev_linux_listen() is called.
This fixes the userspace datapath on FreeBSD.

FreeBSD's system compiler is a somewhat old version of GCC that produced
a spurious warning about a potential unitialized variable use.

This patch adds new netdev classes that implement
"system" and "tap" devices on FreeBSD using the
libpcap library. This enables the use of the
"netdev" datapath_type of Open vSwitch on FreeBSD.
