Fix client latency bug; De-shared_ptr IHopHandler queues
...
- Replace m_FlushWakeup with a call to the router's god mode pump
method. m_FlushWakeup apparently isn't enough to get things out, and
we can end up with incoming packets that don't get properly handled
right away without it.
- The shared_ptr around the ihophandler queues isn't needed and is just
adding a layer of obfuscation; instead just exchange the list directly
into the lambda.
- Use std::exchange rather than swap
- A couple other small code cleanups.

Remove hopeless flush
...
The TriggerPump just below this is *already* going to trigger a flush,
so the extra flush call here can't do anything useful (and in
particular, it won't clear up the queue *immediately*, which is what
this code looks like it was aimed at doing).

Fix packet delay creep
...
- Make the main PumpLL also pump hidden services, rather than using
separate wakers in each TunEndpoint. It seems there is some
interactions that just one or the other is not enough.
- Eliminate TunEndpoint send queue -- it isn't needed as we can just
send directly.

true anymore.

Unleak exit mode DNS via unbound DNS trampoline on (macOS)

When we enable/disable exit mode on this restarts the unbound DNS
responder with the DNS trampoline (or restores upstream, when disabling)
to properly route DNS requests through the tunnel (because libunbound's
direct requests don't get tunneled because unbound is inside the network
extension).
