This pass to json_stream helpers for commands outputs, but keeps
compatibility with existing plugins which use jout as of now, by not
starting/closing the "result"/"error" objects.
Now we have streams and a global object, we can use them for io_plans.
This makes the logic closer from lightningd/plugin (it has been mostly
stolen from here), and simplifies the main.
This also allows plugins to use io_plans (thanks to the io_loop) for
asynchronous connections.
This commit only handle incoming commands.
Now that we have json_stream in common/, we can move all the related
helpers from lightningd/json to common/json. This way everyone can
benefit of them (including libplugin, the plugins themselves,
potentially lightning-cli), not lightningd alone!
Note that the Makefile of the common/test/ had to be modified, because
the new helpers make use of common/wireaddr... Which turns out to
\#include <lightingd/lightningd.h> ! So we couldnt just include the .c
and add mocks if we redefined some structs (hello run-param).
Changelog-Changed: The hooks `db_write`, `invoice_payment`, and `rpc_command` now accept `{ "result": "continue" }` to mean "do default action", in addition to `true` (`db_write`), `{}` (`invoice_payment`), and `{"continue": true}` (`rpc_command`). The older "default" indicators are now deprecated and are now recognized only if `--deprecated-apis` is set.
On CI it is nice to cache the external dependencies. However if we
always compile them in the same folder we cannot cache for multiple
different architectures. After this commit native compile targets will
still live in `external` but cross compiled versions will live in
`external/<arch>`.
Changelog-Added: lightningd: Added --subdaemon command to allow alternate subdaemons.

* Fix usage of `echo "...\n..."` (without `-e`), generating a
broken output:
```
lightningd-config <lightningd-config.5.md>
lightningd\nlightning-autocleaninvoice.7.md <lightningd.8.md\nlightning-autocleaninvoice.7.md>
```
* Use `$(SORT)` instead of bare `sort` to avoid locale-dependent sort.
* Strip the trailing .[0-9].md without invoking sed.
* Sort all man pages as one block.
Changelog-None
Put `LC_ALL=C sort` in a variable and use it everywhere. It was
forgotten in one place.
Without `LC_ALL=C` it would order `a.b` before `a-c` even though
`. (0x2E)` > `- (0x2D)`.
Changelog-None
This sets the nLockTime to the tip (and accordingly each input's nSequence to
0xfffffffe) for withdrawal transactions.
Even if the anti fee-sniping argument might not be valid until some time yet,
this makes our regular wallet transactions far less distinguishable from
bitcoind's ones since it now defaults to using native Segwit transactions
(like us). Moreover other wallets are likely to implement this (if they
haven't already).
Changelog-Added: wallet: withdrawal transactions now sets nlocktime to the current tip.
GCC 10 defaults to `-fno-common`. no longer automatically sharing
global variable definitions, which makes it important to define
them in only one place (otherwise there will be duplicate definition
errors). Add `extern` qualifiers where (I think) is the best place for
them.
ChangeLog-Fixed: Clarified about connection in documentation. Also, `fundchannel` already `connect`s if your node knows how to contact the desired peer for a few versions now, so clarify documentation about this as well.
We are about to disect a couple of invoices for features, so let's add a class
that can encode and decode invoices from bolt11 strings. This is pretty much
the lnaddr.py file created by @rustyrussell with some minor changes. I'm
planning to clean this up further which is why I'm only exporting the
`Invoice` class for now.
Using it with a different value to the amount sent causes a crash in 0.8.0,
which is effectively deprecating it, so let's disallow it now.
Changelog-Changed: If the optional `msatoshi` param to sendpay for non-MPP is set, it must be the exact amount sent to the final recipient.

We also update since the merged version sets feature bit 9 (as it's
supposed to now that we tied that to payment_secret).

We tag them with specific versions when they're experimental,
but do a poor job of cleaning them up (and thus ensuring they're
checked!) afterwards.

Before this patch we used `int` for error codes. The problem with
`int` is that we try to pass it to/from wire and the size of `int` is
not defined by the standard. So a sender with 4-byte `int` would write
4 bytes to the wire and a receiver with 2-byte `int` (for example) would
read just 2 bytes from the wire.
To resolve this:
* Introduce an error code type with a known size:
`typedef s32 errcode_t`.
* Change all error code macros to constants of type `errcode_t`.
Constants also play better with gdb - it would visualize the name of
the constant instead of the numeric value.
* Change all functions that take error codes to take the new type
`errcode_t` instead of `int`.
* Introduce towire / fromwire functions to send / receive the newly added
type `errcode_t` and use it instead of `towire_int()`.
In addition:
* Remove the now unneeded `towire_int()`.
* Replace a hardcoded error code `-2` with a new constant
`INVOICE_EXPIRED_DURING_WAIT` (903).
Changelog-Changed: The waitinvoice command would now return error code 903 to designate that the invoice expired during wait, instead of the previous -2

If the same memory gets reallocated, our "has the tip changed?" test
gets a false negative. This happened for me about one time in 10,
causing tests/test_misc.py::test_funding_reorg_remote_lags to fail.

This shouldn't happen if channeld is working properly, but I'm going to
change that, and this current code means we stop responding at that point
(not every failpath in peer_accepted_htlc() called channel_internal_error).

1. We asserted that there wouldn't be a raw failcode.
2. We didn't pass the failure information via JSON in this case.
