Fix regression in Path MTU discovery
...
In the past we used to send back anything up to 900 bytes of the packet in the ICMPv6 Packet Too Big response, whereas now we seemingly only send back 40 bytes.
It turns out that sending back only the 40 bytes of IPv6 headers isn't enough for most operating systems to positively ID the flow to reduce the MTU. This PR updates it so that we can send up to 512 bytes instead (900 is probably excessive) — that should leave plenty of room for any number of IPv6 extension headers and the next protocol headers and some of the payload.
This seems to fix the problem in my testing.

if the link handler exits early due to an existing connection, then have it return a channel to that connection which closes when the connection is closed, so we can choose to block on that to avoid spamming connection attempts with dial

remove link.go block on oldIntf if we already have a connection to the same node, this spams connections, so it's not a good long-term fix if that's where the goroutine leak is

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.

adjust how sessions learn source routes, try to recover faster if coords change (but assume the old path still works until we get a ping through that gives us a new path)
