That matches the other CSV names (HSM was the first, so it was written
before the pattern emerged).

this enables addr like --addr=autotor:127.0.0.1 or
--addr=autotor:localhost to just use the default tor service port

Code changes:
1. Expose daemon_poll() so lightningd can call it directly, which avoids us
having store a global and document it.
2. Remove the (undocumented, unused, forgotten) --rpc-file="" option to disable
JSON RPC.
3. Move the ickiness of finding the executable path into subd.c, so it doesn't
distract from lightningd.c overview.

We want to exclude the child from being entered into the htable:
if we wanted the parent we could do this outside the loop.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
memleak can't see into htables, as it overloads unused pointer bits.
And it can't see into intmap, since they use malloc (it only looks for tal
pointers).

I managed to crash the HSM by asking for point -1 (shachain_index has an
assert). Fail in this case, instead.

To be safe, we should never memcmp secrets. We don't do this
currently outside tests, but we're about to.
The tests to prove this as constant time are the tricky bit.

Tests were failing when in the same thread after a test which set
log_all_io=True, because SIGUSR1 seemed to be turning logging *off*.
This is due to Python using references not copies for assignment.

This is required for the next test, which has to log messages from channeld
as soon as it starts (so might be too late if it sends SIGUSR1).

We ignore incoming for now, but this means we advertize the option and
we send the required fields.

This is a wrapper around shachain_get_hash, which converts the
commit_num to an index and returns a 'struct secret' rather than a
'struct sha256' (which is really an internal detail).

This was a very simple change and allowed us to remove the special
`json_opt_tok` macro.
Moved the callback out of `common/json.c` to `lightningd/json.c` because the new
callbacks are dependent on `struct command` etc.
(I already started on `json_tok_number`)
My plan is to:
1. upgrade json_tok_X one a time, maybe a PR for each one.
2. When done, rename macros (i.e, remove "_tal").
3. Remove all vestiges of the old callbacks
4. Add new callbacks so that we no longer need json_tok_tok!
(e.g., json_tok_label, json_tok_str, json_tok_msat)

Avoid that 200ms loss. We don't want to disable nagle generally,
since it's great for gossip and other traffic; we just want to push at
critical times.

We currently hand the error back to the master, who then stores it for
future connections and hands it back to another openingd to send and exit.
Just send directly; it's more reliable and simpler.

Also means we simplify the handle_gossip_msg() since everyone wants it to
use sync_crypto_write().

The One Big API is confusing, and has enough corner cases that we should
ditch it rather than add more.

In particular, when openingd is changed to chat to peers even when
it's not actively opening a channel, it wants to handle (most) errors
by continuing, not calling peer_failed().
This exposes the constituent parts.

It no longer has any effect on tal_len(), but it *does* give file and line
of allocations which is much nicer for tracking memory leaks!

In some daemons I want to hand it into a loop, which would call
clean_tmpctx(). This causes a subtle bug.
So just free the children directly: the pointer itself remains valid.

The easiest way to do this is to play with the 'wallet_tx' semantics
and have 'amount' have meaning even when 'all_funds' is set.
Note that we change the string 'Cannot afford funding transaction' to
'Cannot afford transaction' as this code is also used for withdrawls.

In several places we use low-level tal functions because we want the
label to be something other than the default. ccan/tal is adding
tal_*_label so replace them and shim it for now.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
tal_count() is used where there's a type, even if it's char or u8, and
tal_bytelen() is going to replace tal_len() for clarity: it's only needed
where a pointer is void.
We shim tal_bytelen() for now.

There are three cases:
1. failcode is 0, scid is NULL, failreason is the onion to fwd.
2. failcode is non-zero, but UPDATE bit not set. scid is NULL, failreason NULL.
3. failcode has UPDATE bit set. scid is non-NULL, failreason is NULL.
Assert these on marshaling, and only send the parts we need so unmarshal is
always canonical.

The master tells us the short_channel_id of the outgoing channel when
failing an HTLC, but channeld didn't store it anywhere. It also
didn't tell channeld the short_channel_id in the case where we're
reconnecting and it's feeding us an array of failed htlcs.

That was the cause of the bad gossip order failures: gossipd thought our
channel was live, but the other end didn't receive message last time.
Now gossipd doesn't use fd to kill us (connectd tells master to do so), we
can implement read_peer_msg_nogossip().
