Brad Fitzpatrick b560386c1a net/packet, wgengine, tstun: add inter-node TSMP protocol for connect errors
This adds a new IP Protocol type, TSMP on protocol number 99 for
sending inter-tailscale messages over WireGuard, currently just for
why a peer rejects TCP SYNs (ACL rejection, shields up, and in the
future: nothing listening, something listening on that port but wrong
interface, etc)
