Use large kernel buffers for the UDP socket when uTP is enabled.
...
Since we're using a single UDP socket to implement multiple uTP sockets,
and since we're not always timely in servicing an incoming UDP packet,
it's important to use a large receive buffer. The send buffer is probably
less critical, we increase it nonetheless.

Don't call tr_utpClose in toggle_utp.
...
The uTP timer needs to run even when uTP has been disabled, or else the
uTP sockets will never time out.

When uTP is enabled, open uTP connections to some peers.
...
Since we don't implement falling back to TCP yet, we're very
conservative: we only use uTP when we have good reasons to believe
the peer speaks uTP.

This should cause uTP sockets to respect read bandwidth limits. I'm not so

should allow some slack for network latency?

Push testig for UTP enabled further down.
...
There's no need to test for DHT/uTP being enabled in tr-udp. The DHT
will silently discard any packets directed at the wrong session (see the
beginning of dhtCallback). As to uTP, we need to grok uTP packets
to close any remaining connections after we disabled uTP, so it's better
to participate in uTP, just reject any incoming connections.

Libutp will sometimes call our callbacks after we called UTP_Close,
notably to notify us of the UTP_STATE_DESTROYING state change, but
also, for some reason, to ask us about our read buffer. The simplest
way to avoid issues with that is to switch to a second set of callbacks.
