1. Add remote_ann_node_sigs and remote_bitcoin_sigs fields in channel_init message;
2. Master add announcement signatures into channel_init message, and send this message to Channeld.
Channeld will initial the channel with this signatures when it reenables the channel.
Channeld sends announcement signatures to Master by this message.
When Channeld receive a new channel announcement msg, (After channel locking)it will sends announcement signatures to Master by this message.
Reorg changes short_channel_id after lockin of private channel, while
one node restarts.
test that:
- peer->depth_togo in billboard decrements
- reorg and scid change is detected by running node and restarting node
- both `old` and `new` scids are in rtable
Also added a comment to test_blockchaintrack to clarify.
Keep watching and updating scid until ANNOUNCE_MIN_DEPTH, even when channel is private.
When scid changes, we fail channeld so it will restart and initialize with updated
scid and add it to rtable. Reorgs can change funding tx's height/index after lockin,
which could happen with small minimum_depth=1.
Now without bitcoind restart.
bitcoin-cli `prioritisetransaction` came to the rescue!
Its argument `fee_delta` (apparently) lowers the txs _effective_ feerate
soo low that bitcoind wont mine it ... untill we raise it when we want
it to be mined.
Because the call (wallet_extract_owned outputs) that prints that line can happen
_before_ or _after_ confirmation in block, adding `CONFIRMED` in the later.
Fixes: #2659
Value randomization is not implemented since `pay` was made into a plugin.
Nobody has been asking for it, so do not implement it and just remove
from documentation.
Shadow routes is implemented, and not describe, so describe it now.
Tries to return the approxmost posible string of a Millisatoshi amount using
various unit representations. The function will round to an effective
number of digits. Default: 3.
```
>>> Millisatoshi("100000sat").to_approx_str()
'0.001btc'
>>> Millisatoshi("100msat").to_approx_str()
'0.1sat'
>>> Millisatoshi("10000000sat").to_approx_str()
'0.1btc'
```
Each destructor2 costs 40 bytes, and struct chan is only 120 bytes. So
this drops our memory usage quite a bit:

This has two effects: most importantly, it avoids the problem where
lightningd creates a 800MB JSON blob in response to listchannels,
which causes OOM on the Raspberry Pi (our previous max allocation was
832MB). This is because lightning-cli can start draining the JSON
while we're filling the buffer, so we end up with a max allocation of
68MB.
But despite being less efficient (multiple queries to gossipd), it
actually speeds things up due to the parallelism:

We use raw malloc here, again, to handle the failure cases more easily.
I tested it with this hack, then ran the result through `jq --stream '.'`
before and after to make sure it was the same.

This happened with the 800M JSON for the MCP listchannels on the raspberry
pi, and tal calls abort() by default.
We switch to raw malloc here; we could override the error hook for
tal, but this is neater since we're doing low-level things anyway,
I tested it manually with this patch:

We now have a test blockchain for MCP which has the correct channels,
so this is not needed.
Also fix a benchmark script bug where 'mv "$DIR"/log
"$DIR"/log.old.$$' would fail if you log didn't exist from a previous run.

This brings up an interesting quirk though, in that we report "3
attempts", where we really should have done one.
