Rusty Russell 2da5244e83 jsonrpc: make error codes an enum.
This allows GDB to print values, but also allows us to use them in
'case' statements.  This wasn't allowed before because they're not
constant terms.

This also made it clear there's a clash between two error codes,
so move one.

Rusty Russell 401f1debc5 common: clean up json routine locations.
We have them split over common/param.c, common/json.c,
common/json_helpers.c, common/json_tok.c and common/json_stream.c.

Change that to:
* common/json_parse (all the json_to_xxx routines)
* common/json_parse_simple (simplest the json parsing routines, for cli too)
* common/json_stream (all the json_add_xxx routines)
* common/json_param (all the param and param_xxx routines)

Rusty Russell 35e3c1866e common: generalize extract_channel_id().
connectd is going to end up using this do demux; make it fast and complete.

Fixing this reveals a problem in openingd: it now extracts the channel_id
from funding_signed (which is where we transition off the temporary), and
gets upset.  So fix that.

Rusty Russell 4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).

config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

Rusty Russell 3ed03f9c8f common: make json_parse_input API retry friendly.
The jsmn parser is a beautiful piece of code.  In particular, you can parse
part of a string, then continue where you left off.

We don't take advantage of this, however, meaning for large JSON objects
we parse them multiple times before finally having enough to complete.

Expose the parser state and tokens through the API, so the caller can pass
them in repeatedly.  For the moment, every caller is allocates each time
(except the unit tests).

One is called on every plugin return, and tells us whether to continue;
the other is only called if every plugin says ok.

We should probably turn everything into a chained callback next
release.

darosior a0df49718a lightningd/jsonrpc: Add a 'rpc_command' hook
The 'rpc_command' hook allows a plugin to take over any RPC command.
It sends the complete JSONRPC request to the plugin, which can then respond
with :
- {'continue'}: executes the command normally
- {'replace': {a_jsonrpc_request}}: replaces the request made
- {'return': {'result': {}}}: send a custom response
- {'return': {'error': {}}}: send a custom error

This way, a plugin can modify (/reimplement) or restrict the usage of
any of `lightningd`'s commands.

Rusty Russell ca53c1b699 gossipd: push our own gossip messages harder.
I had a report of a 0.7.2 user whose node hadn't appeared on 1ml.  Their
node_announcement wasn't visible to my node, either.

I suspect this is a consequence of recent version reducing the amount of
gossip they send, as well as large nodes increasingly turning off gossip
altogether from some peers (as we do).  We should ignore timestamp filters
for our own channels: the easiest way to do this is to push them out
directly from gossipd (other messages are sent via the store).

We change channeld to wrap the local channel_announcements: previously
we just handed it to gossipd as for any other gossip message we received
from our peer.  Now gossipd knows to push it out, as it's local.

This interferes with the logic in tests/test_misc.py::test_htlc_send_timeout
which expects the node_announcement message last, so we generalize
that too.

The difference between lightningd's json-writing ringbuffer and the
more generic ccan/json_out is that the latter has a better API and
handles escaping transparently if something slips through (though
it does offer direct accessors so you can mess things up yourself!).

trueptolemy 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.
