I reduced that constant in libwally to 200, and ran the entire
test suite, and found no other places.

Just applied the same suppression as rusty in:
6635fe12e4 (Rusty Russell 2020-05-15 15:57:29 +0930 146)
/* cppcheck-suppress uninitvar - false positive on f1->bits */
My cppcheck was complaining about the same issue in the following functions.
I wonder why travis does not care though.

This will allow nodes (with log-level=debug) to gather how many payments
are made without payment_secrets. We need to know this so we know when
we can make them compulsory.

1. One place returned false instead of -1.
2. The names implied it returned a bool, and it doesn't.
Fix both, and curse C's loose typing a little.

We let the plugin decide what feerate to accept/whether or not to add
funds to the open. To aid this decision, we also send the plugin what we
(c-lightning) currently have as our max and min acceptable feerates.
We also now use these as our default for max/min acceptable feerate
range when sending an openchannel offer to a peer.
In the future, it might be a good idea to make these more easily
changeable, either via a config setting (?) or a command param.
The previous dev-force-features forced you to explicitly declare every
desired feature bit in an array, for each set.
Here, we allow you to also denote adding/subtracing a feature bit
by just passing in the number of the bit to flip and the direction to
turn it. e.g.
'dev-force-features': '+223'
Will turn on opt_dual_fund/odd.
'dev-force-features': '-16'
Will flag off opt_basic_mpp.
There's a spec rule about only ever sending a correctly sized
feature-bits, so as a precaution we have `clear_feature_bit` correctly
resize when a bit is cleared.

"make clean" removes all object files listed in $(ALL_OBJS), which is derived from $(ALL_C_SOURCES).
Source files in $(LIGHTNINGD_SRC_NOHDR) are missing from $(ALL_C_SOURCES) therefore some object files are not removed by "make clean".
This commit fixes this point.

Changelog-None
This will change the current hardwired PostgreSQL binary lookup mechanism to
utilizing the `pg_config --bindir` utility that should work better for most
distributions. The old method caused issues at least on Archlinux.
Changelog-None
libwally has a quirk where the finalize method will fail to 'completely'
finalize an input's parts if either the final_scriptsig or
final_redeemscript fields are set
since we manually set the final_witness stack here, we also need to
fully finalize the redeemscript -> final_scriptsig here as well.
For compatibility, we only do this if `allow-deprecated-apis` is false
for now. Otherwise scripts parsing should use `grep -v '^# '` or
start using `-N none`.
Changelog-Added: JSON-RPC: `close` now sends notifications for slow closes (if `allow-deprecated-apis`=false)
Changelog-Deprecated: cli: scripts should filter out '^# ' or use `-N none`, as commands will start returning notifications soon
Fixes: #3925

This can be suppressed with -N.
Note that we wull get an error with older lightningd, but we ignore it
anyway.

We also sanity check that response id matches our request.

Changelog-Added: pyln: pyln.client handles and can send progress notifications.
This lets callers enable notifications; we won't send any if they don't.

Changelog-Added: JSON-RPC: `notifications` command to enable notifications.
And make caller of json_stream_forward_change_id use it, since
we're going to reuse that.
Also call json_out_finished here, so next object doesn't have a ","
prepended.

- Adds bitarray filling so mesages of any length can be encoded, instead of forcing the encoding to be of messages with length multiple of 5.
- Adds checks for encoding / decoding and raises expections if the inputs are not as expected.
- Flags functions that are supposed to be internal as "private".
