Jason A. Donenfeld 49f287439e PacketTunnelSettingsGenerator: use 127.0.0.1 as dummy address 
It turns out that using 0.0.0.0 somehow conflicts with DNS lookups when
CLAT is in use.

Jason A. Donenfeld 0b828f9b96 Rework DNS and routes in network extension 
The DNS resolver prior had useless comments, awful nesting, converted
bytes into strings and back into bytes, and generally made no sense.
That's been rewritten now.

But more fundumentally, this commit made the DNS resolver actually
accomplish its objective, by passing AI_ALL to it. It turns out, though,
that the Go library isn't actually using GAI in the way we need for
parsing IP addresses, so we actually need to do another round, this time
with hints flag as zero, so that we get the DNS64 address.

Additionally, since we're now binding sockets to interfaces, we can
entirely remove the excludedRoutes logic.

Roopesh Chander 28ce4d5164 NE: Change handling of bad domain names and Activate On Demand 
The solution implemented in commit b8c331c causes the tunnel to
remain in 'Activating' state, without the ability to cancel that.

So, in this commit, instead of retrying DNS silently on
Activated-On-Demand tunnels, we fail the startTunnel() silently.

To summarize, if activate-on-demand is on:
- If started from the WireGuard app, show error using lastErrorFile
mechanism, suggesting a way to turn off Activate On Demand
- If not started from WireGuard app, don't call displayMessage()
(don't show error to user) and silently fail starting the tunnel

Roopesh Chander fa51e3f1d1 NE: Handle bad domain names and Activate On Demand 
This combination causes iOS to keep trying to bring up the tunnel,
leading to a lot of displayMessage() alerts.

In this fix, if we get a DNS resolution error in an Activate On Demand
enabled tunnel, we silently retry 9 times (with a 4-second delay before
each retry) and then show the displayMessage() alert.
