e67d8c6314 Don't unwrap() get_channel_update result in HTLC router 
This fixes a bug in 78232f2aed found
by fuzzer - if the channel isn't yet fully established we will call
get_channel_update(), get an Err result, and then unwrap() it. If
this actually happens it means someone on the network is making up
short_channel_ids and trying to route over them, but that shouldn't
result in us crashing

b4fc5b65e0 Fix pre-noise peer disconnect panic on non-Err disconnect 
366e79615b fixed the same crash for
Errs that come up during handshake, but was incomplete and should
have just dropped the node_id being different based on
inbound/outbound. This patch does so and actually fixes the issue.

Found by fuzzer.

4a697dbdf2 Expand test_funding_peer_disconnect somewhat by being non-symmetric 
I thought I found a bug in one-side-funded-first reconnect, but
seems I can't reproduce it here. Either way worth improving the
test coverage.

See https://github.com/lightningnetwork/lightning-rfc/issues/499
for a bit more about the ambiguity we're addressing here.

Also drop holding cell update_fee the same way we drop holding
cell update_add_htlcs when sending shutdown, resolving a bug.

366e79615b Fix pre-noise outbound peer disconnect panic found by fuzzer 
If we make an outbound connection to a peer who we are already
connected to, and the outbound connection fails
pre-noise-completion, we will remove the original peer connection
from our node_id_to_descriptor map.

The fuzzer managed to find this by crashing in Channel's assertions
that we don't do a get_channel_reestablish() when the Channel isn't
already marked disconnected.

1993ec0d12 Always send Shutdown resposnes to Shutdown messages 
We always require that any changes to Channel state be committed
immediately (within the same lock) so we should never have
uncommitted changes which would prevent us from sending a Shutdown
response.

55a74b5dab Use non-funder's funding block wait instead of max with ours 
This is both required by the protocol and also makes sense - if
we're the funder we don't mind accepting payment on the channel
after one confirmation because we assume we won't double-spend
ourselves.
