We still get the shared secret, since that requires a round trip to the HSM
(why waste the master daemon's time?) but it does the processing, which
simplifies the message passing and things like realm handling which
have nothing to do with this particular channeld.

Some paths were still sending unencrypted failure messages; unify them
all. We need to keep the fail_msg around for resubmission if the
channeld dies; similarly, we need to keep the htlc_end structure
itself after failure, in case the failed HTLC is committed: we can
move it to a minimal archive once it's flushed from both sides,
however.

Means caller has to do some more work, but this is closer to what we want:
we're going to want to send them to the master daemon for atomic commit.

I have a test which waits for multiple occurrences of the same string,
but doesn't want them to overlap. Make wait_for_log() do the right thing,
so that it only looks for log entries since the last wait_for_log.

On my laptop under load, 5 seconds was no longer enough for legacy.
But this breaks async (they all see mempool increase, and fire
prematurely), so stop doing that.
I can't get this test to work at all, in fact, without this patch.

We used level -1 to mean "append to log", but that doesn't actually
work, and results in an assert if we try to prune the logs:
lightningd: daemon/pseudorand.c:36: pseudorand: Assertion `max' failed.
Expose logv_add and use that.

We use --log-level to control this, but we could add another switch.
It makes the test infrastructure simpler, since we can just look in the
main logs.

I actually hit this very hard to reproduce race: if we haven't process
the channeld message when block #6 comes in, we won't send the gossip
message. We wait for logs, but don't generate new blocks, and timeout
on l1.daemon.wait_for_log('peer_out WIRE_ANNOUNCEMENT_SIGNATURES').
The solution, which also tests that we don't send announcement signatures
immediately, is to generate a single block, wait for CHANNELD_NORMAL,
then (in gossip tests), generate 5 more.

Since we have a simple way to query the database for UTXOs we can
simplify some of the coin selection logic. That gets rid of the
in-memory list of UTXOs.
Not the nicest code, but it allows us to store the bip32_max_index so
that we don't forget our addresses upon restart. We could have done
the same by retrieving the max index from our index, but then we'd
forget addresses that don't have an associated output. Conversion
to/from string is so that we can store arbitrary one off values in the
DB in the future, independent of type.
The format we use to generate marshal/unmarshal code is from
the spec's tools/extract-formats.py which includes the offset:
we don't use it at all, so rather than having manually-calculated
(and thus probably wrong) values, or 0, emit it altogther.

We use this to make it send the funding_signed message, rather than having
the master daemon do it (which was even more hacky). It also means it
can handle the crypto, so no need for the packet to be handed up encrypted,
and also make --dev-disconnect "just work" for this packet.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We use a file descriptor, so when we consume an entry, we move past it
(and everyone shares a file offset, so this works).
The file contains packet names prefixed by - (treat fd as closed when
we try to write this packet), + (write the packet then ensure the file
descriptor fails), or @ ("lose" the packet then ensure the file
descriptor fails).
The sync and async peer-write functions hook this in automatically.

This is simpler than passing back and forth, for the moment at least. That
means we don't need to ask for a new one on reconnect.
This partially reverts the gossip handling in openingd, since it no longer
passes the gossip fd back. We also close it when peer is freed, so it
needs initializing to -1.

We can go to release a gossip peer, and it can fail at the same time.
We work around the problem that the reply must be a gossipctl_release_peer_reply
with two fds, but it's not pretty.

We kill the existing connection if possible; this may mean simply
