autoconf on BSD should be more intelligent when selecting TAP devices

[neilalexander]

Interesting note from the tap manpage on FreeBSD:

If the sysctl(8) variable net.link.tap.devfs_cloning is non-zero, the tap
interface permits opens on the special control device /dev/tap. When
this device is opened, tap will return a handle for the lowest unused tap
device (use devname(3) to determine which).

(also https://www.freebsd.org/cgi/man.cgi?query=devname&sektion=3&apropos=0&manpath=freebsd)

Closing as Yggdrasil no longer supports TAP devices.
