Change DefaultIfName from "/dev/tun0" to "tun0"
...
Specifying the full path to the interface in OpenBSD would result in:
panic: Interface name must be tun[0-9]*
Therefore, DefaultIfName should be changed to tun0 in order to make yggdrasil work out of the box.

Unify MTU datatypes across the codebase
...
The codebase uses int and unit16 to represent MTU randomly. This change
unifies it to a MTU type from types package, which is currently uint16.

always keep the 2 closest nodes in each direction around the dht ring, possibly helps things recover faster after joins/leaves

ihl may grow upto 15*4=60 so extract and check it before using it as offset in flowkey calculation.
also replace IFs with switches for protocol matching as it's less redundant and nicer to document.
