David Anderson 76d99cf01a wgengine/filter: remove the Matches type.
It only served to obscure the underlying slice type without
adding much value.

David Anderson b3634f020d wgengine/filter: use netaddr types in public API.
We still use the packet.* alloc-free types in the data path, but
the compilation from netaddr to packet happens within the filter
package.

Avery Pennarun 5041800ac6 wgengine/tstun/faketun: it's a null tunnel, not a loopback.
At some point faketun got implemented as a loopback (put a packet in
from wireguard, the same packet goes back to wireguard) which is not
useful. It's supposed to be an interface that just sinks all packets,
and then wgengine adds *only* and ICMP Echo responder as a layer on
top.

This caused extremely odd bugs on darwin, where the special case that
reinjects packets from local->local was filling the loopback channel
and creating an infinite loop (which became jammed since the reader and
writer were in the same goroutine).

Brad Fitzpatrick 23e74a0f7a wgengine, magicsock, tstun: don't regularly STUN when idle (mobile only for now)
If there's been 5 minutes of inactivity, stop doing STUN lookups. That
means NAT mappings will expire, but they can resume later when there's
activity again.

We'll do this for all platforms later.
