Rusty Russell e683649004 connectd: maintain connection with peer, shuffle data.
Instead of passing the incoming socket to lightningd for the
subdaemon, create a new one and simply shuffle data between them,
keeping connectd in the loop.

For the moment, we don't decrypt at all, just shuffle.  This means our
buffer code is kind of a hack, but that goes away once we start
actually decrypting and understanding message boundaries.

This implementation is naive: it closes the socket to the local daemon
as soon as the peer closes the socket to us.  This is fixed in a
successive patch series (along with many other similar issues).

Rusty Russell 8f3b390356 pytest: make test_channel_state_changed_unilateral more robust.
This test started mostly failing (in non-DEVELOPER mode) after the
next patch, due to timing issues.

Handle both cases for now, and we'll add more enhancements later to
things we should be handling more consistently.

Rusty Russell 7e7a63a20d connectd: keep timeout timer around so we can disable it.
connectd will be keeping the conn open, so it needs to free this
"conn_timeout" timer.  Pass it through, so we can do that.

Vincenzo Palazzo 35eaaf8e63 cli: change the redefine logic to read from the stdin
Procedure redefinition is a very cool feature but when other libraries redefine the same function can be very tricky to avoid compilation error.

This PR proposed a change of logic and use a customizzation function definition to read from the stdin, so we can avoid future error at compile time.

However, we could be check also the os or compiler that cause the error and redefine the missing function.

Changelog-None: Fixed compilation error due redefinition procedure.

Rusty Russell 425a7af512 common/coin_mvt: clean up API a little.
1. tal_strndup(.., str, strlen(str)) == tal_strdup()
2. tal_strdup also takes(), so document that.
3. Avoid passing 'struct sha256' on the stack: use ptr.
4. Generally, structures shouldn't keep pointers to things they don't own.
   In this case, mvt->node_id.
5. Make payment_hash a pointer, since NULL is more natural than an all-zero
   hash.

And add NON_NULL_ARGS() to the functions; it's cumbersome, but make it
fairly clear what params are optional.

Rusty Russell 0aad222c2d gossipd: rewrite update generation, remove local_chan.
local_chan was mainly around so we could "soft" disable channels (and
really disable them once we used the channel_update in an error
message).

Instead we introduce the idea of a "deferred_update": it's either
deferred indefinitely (a peer goes offline, if we need to send it in
an error we'll apply it immediatly), or simply delayed to avoid
spamming everyone.

The resulting rewrite is much clearer, IMHO.

1. Freeing an unconfirmed channel already releases the subd, so don't

niftynei 8225a9decf coin_mvt: log events for pushes/lease_fees for leased channels
We need to stash/save the amount of the lease fees on a leased channel,
we do this by re-using the 'push' amount field on channel (which is
technically correct, since we're essentially pushing the fee amount to
the peer).

Also updates a bit of how the pushes are accounted for (pushed to now
has an event; their channel will open at zero but then they'll
immediately register a push event).

Leases fees are treated exactly the same as pushes, except labeled
differently.

Required adding a 'lease_fee' field to the inflights so we keep track of
the fee for the lease until the open happens.

niftynei bddd3694fa coin_mvt: record fees for an outbound htlc

inbound htlc and the outbound (net gain by this routing)

out-routed payment.

niftynei d2c4d4aec2 coin_mvts: rewrite how onchain events are recorded, update tests
The old model of coin movements attempted to compute fees etc and log
amounts, not utxos. This is not as robust, as multi-party opens and dual
funded channels make it hard to account for fees etc correctly.

Instead, we move towards a 'utxo' view of the onchain events. Every
event is either the creation or 'destruction' of a utxo. For cases where
the value of the utxo is not (fully) debited/credited to our account, we
also record the output_value. E.g. channel closings spend a utxo who's
entire value we may not own.

Since we're now tracking UTXOs onchain, we can now do more complex
assertions about the onchain footprint of them. The integration tests
have been updated to now use more 'chain aware' assertions about the
ending state.
