This allows us to set more fine-grained feerate for onchain resolution.
We still give it the same feerate for all types, but this will change as
we move feerates to bcli.
This is ignored in subdaemons which are per-peer, but very useful for
multi-peer daemons like connectd and gossipd.

We now have a pointer to chainparams, that fails valgrind if we do anything
chain-specific before setting it.
Suggested-by: Rusty Russell <@rustyrussell>
Turns out that if we have the init message contain both the chainparams as
well as a transaction that needs to be parsed we need to set the parser to
elements mode before we reach the transaction...
This is the main reason we started weaving the chainparams everywhere: being
able to compare the asset type with the fee paying asset tag, thus determining
the value of the asset correctly (we still treat any non-fee-paying assets as
having value 0).

The largest change is inside hsmd: it hands a null per-commitment key
to the wallet to tell it to spend the to_remote output.
It can also now resolve unknown commitments, even if it doesn't have a
possible_remote_per_commitment_point from the peer.

`make update-mocks` is usually run in DEVELOPER mode, but then it includes
definitions for functions which aren't declared in non-DEVELOPER mode.
We hacked this in a few places, but it's fragile, and worst, now we
have EXPERIMENTAL_FEATURES as well, it's complex.
Instead, declare developer-only functions (but don't define them).
This is a bit more awkward if you accidentally use one in
non-DEVELOPER code (link error rather than compile error), but makes
autogenerating test mocks much easier.

The way we build transactions, serialize them, and compute fees depends on the
chain we are working on, so let's add some context to the transactions.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
The `wally_tx_input`s do not keep track of their input value, which means we
need to track them ourselves if we try to sign these transactions at a later
point in time.

onchaind is in the correct position to tell us about them, so have it pass
them up as well.

As a side-effect of using amount_msat in gossipd/routing.c, we explicitly
handle overflows and don't need to pre-prune ridiculous-fee channels.

This is prep work for when we sign htlc txs with
SIGHASH_SINGLE|SIGHASH_ANYONECANPAY.
We still deal with raw signatures for the htlc txs at the moment, since
we send them like that across the wire, and changing that was simply too
painful (for the moment?).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
For onchaind we need to remove globals from memleak consideration;
we also change the htlc pointer to an htlc copy, which simplifies
things as well.

@renepickhardt: why is it actually lightningd.c with a d but hsm.c without d ?
And delete unused gossipd/gossip.h.

This is a wrapper around shachain_get_hash, which converts the
commit_num to an index and returns a 'struct secret' rather than a
'struct sha256' (which is really an internal detail).

tal_count() is used where there's a type, even if it's char or u8, and
tal_bytelen() is going to replace tal_len() for clarity: it's only needed
where a pointer is void.
We shim tal_bytelen() for now.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This means onchaind doesn't need the per-channel secret at all (aka. peer seed)
so we remove that from the onchaind_init message.

As of bitcoind 0.16.1, you can't send a single-input OP_RETURN output,
as you get 'tx-too-small'.
sendrawtx exit 26, gave error code: -26?error message:?tx-size-small (code 64)?'
So instead we use the minimum fee we can, but otherwise ignore it and
don't wait for it to be mined.
