fix up some retarded bullshit
* llarp::service::NameIsValid was not checking that the tld was .loki, add this check.
* make link layer initial connection timeout 5s not the session activity timeout which happens to be 60 god damn seconds.

Reduce max number of per-connection active streams to 32
This is the max number of simultaneous open connections to the same port
on the remote.  100 was fairly arbitrary and seems a bit high.

Fix connection close handling
Replace stream_reset (which typically isn't called) with a stream_close
handler (which is already called whether or not it was a reset).  Most
importantly, the server side needs to extend the max bidi streams
counter during stream_close (otherwise we run out when we hit the
limit and new connections just stall).

Replace timer->again() with stop/start()
repeat()/again() sets a repeating timer, which we don't want; stop and
start it instead so that it fires just once.

Don't install stream forwarding here
Stream forward on the client-side TCP connection gets set up within in
initial_client_data_handler (which also handles reading the initial
stream version byte).

Simplify/fix expiry timer logic
Also fix a potential transmission delay because `again()` wasn't being
called when the expiry is already passed (i.e. meaning we should run
immediately).

Fix/refactor stream closing
Make stream closing with expiring connections work better.  Fixes an
issue where the stream's uv_async could outlive the stream and/or
connection and segfault.

Schedule retransmit after blocked send
In the standalone plainquic code we triggered a retransmit when the
socket became writeable again, but that doesn't work here, so just
schedule it right away to let ngtcp2 worry about retrying.

Sever tunnel links earlier
When we get an error on the tcp connection immediately sever the link to
the quic tunnel so that it doesn't keep trying to forward data to it.

Fix Server's missing opt-out of ring buffer
For now we still steal buffers from uvw.

In the future I'd like to change that, but it's still uvw
work-in-progress to support custom data allocators, and so for now we
still steal data buffers from uvw.

Set port properly in server-to-client reply packets
ngtcp2 was rejecting them because we have the port when constructing,
but then it was 0 on the return packet (which ngtcp2 drops because it's
coming from an unknown/invalid path).
