"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
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 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.

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.

This will allow us to build complex, multi-peer transactions, with
easeTM!
Changelog-Added: EXPERIMENTAL, Plugins: `openchannel_peer_sigs` notification, which contains a peer's signatures for the funding transaction (`opt_dual_fund`)
Prior to this patch update, we expected a client to call
`openchannel_signed` before checking for peer's tx-sigs messages on the
wire.
When moving to a 'multifundchannel' approach, we'll need to be able to
collect sigs from our peers before sending our tx_sigs message. There's
no strict ordering on when tx-sigs messages are sent/received, so this
is fine.
To do this, we go ahead and start up channeld as soon as
commitment_sigs are secured, so that we process incoming tx-sigs from
our peers as soon as we get them.
This is handy/necessary for getting multifundchannel to work, as we need
to know what output to tell all the other peers about.
Changelog-Added: Experimental!! JSON-RPC: openchannel_init returns a field `funding_serial` that indicates the serial_id of the funding output in the provided PSBT
There's a few structs/wire calls that only exist under experimental features.
These were in a common file that was shared/used a bunch of places but
this causes problems. Here we move one of the problematic methods back
into `openingd`, as it's only used locally and then isolate the
references to the `witness_stack` in a new `common/psbt_internal` file.
This lets us remove the iff EXP_FEATURES inclusion switches in most of
the Makefiles.
Rusty pointed out that having an empty channel_id is suboptimal; adding
another call is probably the right idea rather than re-using an existing
one.

...right time.
We re-send the tx_sigs on start/init/reconnect until we've gotten a
funding_locked from our peer. We also build it in channeld now, instead
of in dualopend, and don't pass in a message for them anymore
`openchannel_signed` and `openchannel_update` which allow a user to
continue a openchannel or kick off the completion of a openchannel.
`openchannel_update` should be called until it returns with
`commitments_secured`.
`openchannel_signed` commands hang out across the openingd/channeld
boundary -- we don't return until we've successfully broadcast the
transaction (or timed out waiting for them to send a tx_sigs back).
We need the PSBT to create the finalized tx from once the peer's
tx_signatures are received. Since we're passing the PSBT, we no longer
need the secondary message to be passed, as it was derived from the
PSBT.
Also removes now unused witness serialization code
There are 3 commands for opening a channel with dualfunding.
`openchannel_init` is the first of these.
It initializes the open-channel dialog, and stops once we've run out of
updates (input/outputs) to send to the peer.
Great report from whitslack on this crash at startup:

The problem is a channel with an onchaind can be in state FUNDING_STATE_SEEN,
because onchaind has started but not responded to init yet (which it does once it
has analyzed the commitment tx).
Channel B is onchain, and its onchaind fails the HTLC, and we try to send a msg
to channel A's onchaind as if it were channeld.
Explicitly check if it's channeld, rather than trying to see if it's onchaind.

Changelog-Fixed: crash: assertion fail at restart when source and destination channels of an HTLC are both onchain.
The 100MB log buffer has been the biggest memory footprint for the daemon.
Keeping 10MB for emergency log dumps seems sufficient.
This has been mentioned in the last developer meeting.
Changelog-Changed: In-memory log buffer reduced from 100MB to 10MB
I got a corrupt file, which looked like multiple concurrent attempts
to build it. So instead, build it in one command, but also use
VERBOSE so we print correctly with V=1 (and --quiet).
Also move into plugins/ where it logically belongs.

We force use of tal_wally_start/tal_wally_end around every wally
allocation, and with "end" make the caller choose where to reparent
everything.
This is particularly powerful where we allocate a tx or a psbt: we
want that tx or psbt to be the parent of the other allocations, so
this way we can reparent the tx or psbt, then reparent everything
else onto it.
Implementing psbt_finalize (which uses a behavior flag antipattern)
was tricky, so I ended up splitting that into 'psbt_finalize' and
'psbt_final_tx', which I think also makes the callers clearer.

wallet_commit_channel would fill in the old_remote_per_commit and
fee_states, which is weird since the caller doesn't care.
Make the caller set all the channel_info fields, so wallet_commit_channel
is a simple consumer.
