This removes the reservation cleanup at startup, too, now they're all
using 'reserved_til'.
This changes test_withdraw, since it asserted that outputs were marked
spent as soon as we broadcast a transaction: now they're reserved until
it's mined. Similarly, test_addfunds_from_block assumed we'd see funds
as soon as we broadcast the tx.

Changelog-Changed: JSON-RPC: `withdraw` now randomizes input and output order, not BIP69.
This avoids overwriting the ones in git, and generally makes things neater.
We have convenience headers wire/peer_wire.h and wire/onion_wire.h to
avoid most #ifdefs: simply include those.

We're going to make experimental versions of these completely separate files.
Also remove the dependency on the Makefile itself: it simply causes
unnecessary churn. We can always force-rebuild when we change a rule.

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.

I went overboard on optimization. I am so sorry:
1. Squeezed channel min/max into 16 bits.
2. Uses mmap and leaves node_ids in the file.
3. Uses offsets instead of pointers where possible.
4. Uses custom free-list to allocate inside arrays.
5. Ignores our autogenerated marshalling code in favor of direct derefs.
6. Carefully aligns everything so we use minimal ram.
The result is that the current gossip_store:
- load time (-O3 -flto laptop): 40msec
- load time (-g laptop i.e. DEVELOPER=0): 60msec
- load time (-O0 laptop i.e. DEVELOPER=1): 110msec
- Total memory: 2.6MB:
- 1.5MB for the array of channels
- 512k for the channel htable to map scid -> channel.
- 320k for the node htable to map nodeid -> node.
- 192k for the array of channels inside each node
- 94k for the array of nodes

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).

Our psbt input/output comparison functions use serialization to compare
the things, but if there's a map with things in it and the map isn't
sorted exactly the same, it's highly likely you'll mark an identical inputs
as different.
To fix this, we sort all the input/output maps before linearizing them.
There's no stable ordering on unknown serialization, so linearizing
identical but mis-ordered unknown data will lead to 'wrong' results.
Instead, we just ignore any data that's in the psbt unknown struct.
There's probably also problems here with other PSBT maps. Really, this
needs a finer grained comparison function .... fuck
includes facilities for
- sorting psbt inputs by serial_id
- sorting psbt outputs by serial_id
- adding a serial_id
- getting a serial_id
- finding the diffset between two psbts
- adding a max_len to a psbt input
- getting a max_len from a psbt input
We need to remember this in the db (it's a P2WSH for option_anchor_outputs),
and we need to set nSequence to 1 to spend it.

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).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
HTLC fees increase (larger weight), and the fee paid by the opener
has to include the anchor outputs (i.e. 660 sats).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This simplifies our test matrix, as we never have to handle talking
to peers that specify one but not the other.
This is particularly important for option_anchor_outputs which
assumes option_static_remotekey.

This prevents recompiling everything when you are changing just a doc, or
touching only one file among hundreds of sources, just because the
`gen_version.h` is changed, especially since only one source actually
depends on that header.
It's not all that rare to do these operations, and requiring annotations
for it is a little painful.

Changelog-Changed: JSON-RPC: `delinvoice` will now report specific error codes: 905 for failing to find the invoice, 906 for the invoice status not matching the parameter.
Technically, they could do this themselves, but it's much nicer to have one
place to do it (and it makes sure we get the required information into the
PSBT, which is actually not entirely accessible through listfunds, as that
doesn't want to consult with the HSM for close outputs).

Changelog-Added: JSON RPC: new low-level coin selection `fundpsbt` routine.
We don't preserve detailed asset information at the moment, so provide a
way to convert from a sat to an amount_asset struct.
We also need a way to convert from an 'amount_asset' to a 'value' for
elements, which for explicit (i.e. non-blinded) asssets is a 0x01 prefix
plus the big-endian encoded value.
If you used feerate=750, instead of feerate="750" it didn't work, since the

I now print out all the coin moves in suitable format before we match:
you only see this if the test fails, but it's really helpful.

libwally's API requires us to pass in NULL pointers if the array size is
zero, so we update our array from wire-er to comply with this
requirement
[ Added fix to avoid tal_resize() of NULL -- RR ]
Our existing coin_moves tracking logic assumed that any tx we had an
input in belonged to *all* of our wallet (not a bad assumption as long
as there was no way to update a tx that spends our wallets)
Now that we've got `signpsbt` implemented, however, we need to be
careful about how we account for withdrawals. For now we do a best guess
at what the feerate is, and lump all of our spent outputs as a
'withdrawal' when it's impossible to disambiguate
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.

We're not using the change_outnum for withdraw tx's (and the way
we were calculating it was broken as of the addition of 'multiple
outputs'). This removes the change output knowhow from withdraw_tx
entirely, and pushes the responsibility up to the caller to
include the change output in the output set if desired.
Consequently, we also remove the change output knowhow from hsmd.
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.
Spec is wrong (it says it should be compulsory), and Eclair doesn't set it
at all, leading to an error when they send their announcement_signatures.
