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.

Changelog-Added: cli: print notifications and progress bars if commands provide them.
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".
$(BIN_PROGRAMS) is defined afterwards, leading to the problem that
lightningd doens't get rebuilt (in fact, it was running my installed
lightningd instead!).
It also needs $(PLUGINS) and the subdaemons, so hoist them all.

Note that check-whitespace and check-bolt already do this, so we
can eliminate redundant lines in common/Makefile and bitcoin/Makefile.
We also include the plugin headers in ALL_C_HEADERS so they get
checked.

My bad, i comitted them as part of the LSAN suppressions while this data
race could have and had been fixed.

This:
- Allows `.*btc` amounts (without post-decimal)
- Avoids creating decimals when amount is 0 btc
- Corrects our handling of the suffixes (memeqstr would
sometimes return false because of null-termination)
Changelog-Fixed: We are now able to parse any amount string (XXXmsat, XX.XXXbtc, ..) we create.

This adds a new configuration, --enable-fuzzing (which is more than
welcome to be coupled with --enable-address-sanitizer), to pass the
fuzzer sanitizer argument when compiling objects. This allows libfuzzer
to actually be able "to fuzz" by detecting coverage and be smart when
mutating inputs.
As libfuzzer brings its own ~~fees~~ main(), we compile objects with
fsanitize=fuzzer-no-link, and special-case the linkage of the fuzz
targets.
A "lib" is added to abstract out the interface to the fuzzing tool used.
This allow us to use the same targets to fuzz using AFL, hongfuzz or w/e
by adding their entrypoints into libfuzz. (h/t to practicalswift who
introduced this for bitcoin-core, which i mimiced)

Technically there *are* two feerates that we need to know:
- the feerate to use for the funding transaction, and
- the feerate to tell our peer to use for our commitment txs/htlc txs
As written, `multifundchannel` uses the same feerate for both. This
optional parameter will allow us to differentiate between the two, which
will be exceedingly handy for anchor output worlds. ;)
FIXME: test this
Changelog-Added: JSON API: `multifundchannel` has a new optional argument, 'commitment_feerate', which can be used to differentiate between the funding feerate and the channel's initial commitment feerate
Fixes#4140
Reported-By: @PsySc0rpi0n
Changelog-Fixed: openingd now uses the correct dust limit for determining the allowable floor for a channel open (affects fundee only)
We used to send our tx_sigs before we got to channeld existing. We
changed how this worked so that multifundchannel could live, but failed
to clean up the logic of what "having a psbt around" means wrt channeld
and messaging our peer.
The general idea is that we want to send `tx_signatures` to our peer on
reconnect until they've sent us `funding_locked`.
Note that it's an error to
- send `funding_locked` without having sent `tx_signatures`
- send `tx_signatures` after sending `funding_locked`
We use the 'finalized' state of the peer's inputs/outputs to help signal
where we are in receiving their sigs -- but this doesn't work at all for
opens where the peer doesn't contribute inputs at all.
This isn't really a huge deal, but it does mean that if we receive a
peer's `tx_sigs` more than once (will happen for a reconnect before
`funding_locked`), then we'll issue a notification about receiving their
sigs multiple times. /shrug
