We create ALL_PROGRAMS, ALL_TEST_PROGRAMS, ALL_C_SOURCES and
ALL_C_HEADERS. Then the toplevel Makefile knows which are
autogenerated (by wildcard), so it can have all the rules to clean
them or check the source as necessary.

Fixes: #3608
Changelog-Changed: protocol: Ignore (and log as "unusual") repeated `WIRE_CHANNEL_REESTABLISH` messages, to be compatible with buggy peer software that sometimes does this.
Note that other directories were explicitly depending on the generated
file, instead of relying on their (already existing) dependency on
$(LIGHTNINGD_HSM_CLIENT_OBJS), so we remove that.

This means some files get renamed, and I took the opportunity to clarify
our naming (the *d* is important!)
1. channeld/channel_wire.csv -> channeld/channeld_wire.csv
2. channeld/gen_channel_wire.h -> channeld/channeld_wiregen.h
3. enum channel_wire_type -> enum channeld_wire
4. WIRE_CHANNEL_FUNDING_DEPTH -> WIRE_CHANNELD_FUNDING_DEPTH.

This also means we subtract 660 satoshis more everywhere we subtract
the base fee (except for mutual close, where the base fee is still
used).

This is best done by passing `struct bitcoin_signature` around instead
of raw signatures. We still save raw sigs to the db, and of course the
wire protocol uses them.

HTLC fees increase (larger weight), and the fee paid by the opener
has to include the anchor outputs (i.e. 660 sats).

Includes:
psbt: Use renamed functions for new wally version
psbt: Set the transaction directly to avoid script workarounds
psbt: Use low-S grinding when computing signatures
tx: Use wally_tx_clone from libwally now that its exported

The main change here is that the previously-optional open/accept
fields and reestablish fields are now compulsory (everyone was
including them anyway). In fact, the open/accept is a TLV
because it was actually the same format.
For more details, see lightning-rfc/f068dd0d8dfa5ae75feedd99f269e23be4777381
Changelog-Removed: protocol: support for optioned form of reestablish messages now compulsory.

Update the `bitcoin_tx_add_input` interface to accept a witness script
and or scriptPubkey.
We save the amount + witness script + witness program (if known) to
the PSBT object for a transaction when creating an input.
now that witness script data is saved into the tx/psbt which is
serialized across the wire, there's no reason to use witscript to do
this. good bye witscript!
Since we now over-write the wally malloc/free functions, we need to do
so for tests as well. Here we pull up all of the common setup/teardown
logic into a separate place, and update the tests that use libwally to
use the new common_setup core
Changelog-None
Adds a new plugin notification for getting information about coin
movements. Also includes two 'helper' notification methods that can be
called from within lightningd. Separated from the 'common' set because
the lightningd struct is required to finalize the blockheight etc
Changelog-Added: Plugins: new notification type 'coin_movement'
1. Use status_debug() instead of status_unusual() for when we can't make a
penalty tx (this happens easily the time if we fund a channel).
2. Use status_failed() (which exits) instead of status_broken() (which doesn't!)

`lightningd` passes in all the known penalty_bases when starting a new
`channeld` instance, which tracks them internally, eventually matching them
with revocations and passing them back to `lightningd` so it can create the
penalty transaction. From here it is just a small step to having `channeld`
also generate the penalty transaction if desired.
When we have only a single member in a TLV (e.g. an optional u64),
wrapping it in a struct is awkward. This changes it to directly
access those fields.
This is not only more elegant (60 fewer lines), it would also be
more cache friendly. That's right: cache hot singles!

Previously we've used the term 'funder' to refer to the peer
paying the fees for a transaction; v2 of openchannel will make
this no longer true. Instead we rename this to 'opener', or the
peer sending the 'open_channel' message, since this will be universally
true in a dual-funding world.
The peer will fail the channel on reconnect if we send an 'add' we
don't have balance for yet; we can avoid this issue by always sending
fulfills (+) before sending adds (-)
Note that it's channeld which calculates the shared secret, too. This
minimizes the work that lightningd has to do, at cost of passing this
through.
We also don't yet save the blinding field(s) to the database.
