96135dab5e log: add 'warning' notification when log
- Related Changes for `warning` notification

Add a `bool` type parameter in `log_()` and `lov()`, this `bool` flag
 indicates if we should call `warning` notifier.

1) The process of copying `log_book` of every peer to the `log_book` of
`ld` is usually included in `log_()` and `lov()`, and it may lead to
repeated `warning` notification. So a `bool`, which explicitly indicates
if the `warning` notification is disabled during this call, is necessary
.
2) The `LOG_INFO` and `LOG_DEBUG` level don't need to call
warning, so set that `bool` paramater as `FALSE` for these log level and
only set it as `TRUE` for `LOG_UNUAUSL`/`LOG_BROKEN`. As for `LOG_IO`,
it use `log_io()` to log, so we needn't think about notifier for it.

e1dbc0b12b wallet: clean reserved inputs on startup.
We reserve inputs when we're going to send a transaction, but we don't
unreserve them if we crash.  This is most graphically demonstrated by
the txprepare case, which makes it easier to trigger.

Instead, we should query bitcoind to see whether the tx made it out or
not, as we would do manually with dev-rescan-outputs.

4986d6b39d feat: block of newlines when attaching a logfile
This will make the logger write 4 newlines to re-attached logfiles.
The newlines wont appear on logfiles that are just created.
Additionally the server prints 50 '-' dashes before printing his
startup message, which also help increase readability on logfile.

This was inspired by the way Bitcoin Core handles logfiles.

50f5eb34b4 openingd: take peer before we're opening, wait for explicit funding msg.
Prior to this, lightningd would hand uninteresting peers back to connectd,
which would then return it to lightningd if it sent a non-gossip msg,
or if lightningd asked it to release the peer.

Now connectd hands the peer to lightningd once we've done the init
handshake, which hands it off to openingd.

This is a deep structural change, so we do the minimum here and cleanup
in the following patches.

Lightningd:
1. Remove peer_nongossip handling from connect_control and peer_control.
2. Remove list of outstanding fundchannel command; it was only needed to
   find the race between us asking connectd to release the peer and it
   reconnecting.
3. We can no longer tell if the remote end has started trying to fund a
   channel (until it has succeeded): it's very transitory anyway so not
   worth fixing.
4. We now always have a struct peer, and allocate an uncommitted_channel
   for it, though it may never be used if neither end funds a channel.
5. We start funding on messages for openingd: we can get a funder_reply
   or a fundee, or an error in response to our request to fund a channel.
   so we handle all of them.
6. A new peer_start_openingd() is called after connectd hands us a peer.
7. json_fund_channel just looks through local peers; there are none
   hidden in connectd any more.
8. We sometimes start a new openingd just to send an error message.

Openingd:
1. We always have information we need to accept them funding a channel (in
   the init message).
2. We have to listen for three fds: peer, gossip and master, so we opencode
   the poll.
3. We have an explicit message to start trying to fund a channel.
4. We can be told to send a message in our init message.

Testing:
1. We don't handle some things gracefully yet, so two tests are disabled.
2. 'hand_back_peer .*: now local again' from connectd is no longer a message,
   openingd says 'Handed peer, entering loop' once its managing it.
3. peer['state'] used to be set to 'GOSSIPING' (otherwise this field doesn't
   exist; 'state' is now per-channel.  It doesn't exist at all now.
4. Some tests now need to turn on IO logging in openingd, not connectd.
5. There's a gap between connecting on one node and having connectd on
   the peer hand over the connection to openingd.  Our tests sometimes
   checked getpeers() on the peer, and didn't see anything, so line_graph
   needed updating.

3d3d2ef9af gossipd: remove connectd functionality, enable connectd.
This patch guts gossipd of all peer-related functionality, and hands
all the peer-related requests to channeld instead.

gossipd now gets the final announcable addresses in its init msg, since
it doesn't handle socket binding any more.

lightningd now actually starts connectd, and activates it.  The init
messages for both gossipd and connectd still contain redundant fields
which need cleaning up.

There are shims to handle the fact that connectd's wire messages are
still (mostly) gossipd messages.

92d66a5451 gossipd: take connectd fd on initialization.
connectd has a dedicated fd to gossipd, so it can ask for a new gossip_fd
for a peer.

gossipd has a standalone routine to create a remote peer (this will
eventually be the only way gossipd creates a new peer).

For now lightningd creates a socketpair but doesn't run connectd, so
gossipd never sees any requests on this fd.

This is just copying most of gossipd/gossip.c into connectd/connect.c.
It shares the same wire format as gossipd during transition, and changes
are deliberately minimal.

It also has an additional message 'connect_reconnected' which it sends
to the master daemon to tell it to kill a peer; gossipd relied on
closing the gossipfd to do this, but connectd doesn't maintain an fd
with remote peers.

af065417e1 gossipd: handle wildcard addresses correctly.
If we're given a wildcard address, we can't announce it like that: we need
to try to turn it into a real address (using guess_address).  Then we
use that address.  As a side-effect of this cleanup, we only announce
*any* '--addr' if it's routable.

This fix means that our tests have to force '--announce-addr' because
otherwise localhost isn't routable.

This means that gossipd really controls the addresses now, and breaks
them into two arrays: what we bind to, and what we announce.  That is
now what we return to the master for json_getinfo(), which prints them
as 'bindings' and 'addresses' respectively.

73cd009a4c gossipd/lightningd: use wireaddr_internal.
This replacement is a little menial, but it explicitly catches all
the places where we allow a local socket.  The actual implementation of
opening a AF_UNIX socket is almost hidden in the patch.

The detection of "valid address" is now more complex:

	p->addr.itype != ADDR_INTERNAL_WIREADDR || p->addr.u.wireaddr.type != ADDR_TYPE_PADDING

But most places we do this, we should audit: I'm pretty sure we can't
get an invalid address any more from gossipd (they may be in db, but
we should fix that too).

fe96fe10c7 Clean up network options.
It's become clear that our network options are insufficient, with the coming
addition of Tor and unix domain support.

Currently:

1. We always bind to local IPv4 and IPv6 sockets, unless --port=0, --offline,
   or any address is specified explicitly.  If they're routable, we announce.
2. --addr is used to announce, but not to control binding.

After this change:

1. --port is deprecated.
2. --addr controls what we bind to and announce.
3. --bind-addr/--announce-addr can be used to control one and not the other.
4. Unless --autolisten=0, we add local IPv4 & IPv6 port 9735 (and announce if they are routable).
5. --offline still overrides listening (though announcing is still the same).

This means we can bind to as many ports/interfaces as we want, and for
special effects we can announce different things (eg. we're sitting
behind a port forward or a proxy).

What remains to implement is semi-automatic binding: we should be able
to say '--addr=0.0.0.0:9999' and have the address resolve at bind
time, or even '--addr=0.0.0.0:0' and have the port autoresolve too
(you could determine what it was from 'lightning-cli getinfo'.

There are times when reference counting really is the right answer,

9b8fe618f6 pay: remove cmd pointer from htlc_out.
Maintaining it was always fraught, since the command could go away
if the JSON RPC died.  Most recently, it was broken again on shutdown
(see below).

In future we may allow pay commands to block on previous payments, so
it won't even be a 1:1 mapping.  Generalize it: keep commands in a
simple list and do a lookup when a payment fails/succeeds.

dfc132b2fe memleak: add backtrace to allocations.

This also means moving backtrace_state from log.c into lightningd.c, so

c956d9f5eb lightningd: tal memleak detection, dev-memleak command.
This is a primitive mark-and-sweep-style garbage detector.  The core is
in common/ for later use by subdaemons, but for now it's just lightningd.
We initialize it before most other allocations.

We walk the tal tree to get all the pointers, then search the `ld`
object for those pointers, recursing down.  Some specific helpers are
required for hashtables (which stash bits in the unused pointer bits,
so won't be found).

There's `notleak()` for annotating things that aren't leaks: things
like globals and timers, and other semi-transients.
