Rusty Russell 00cb5adfe6 common: allow subdaemons to specify the node_id in status messages.
This is ignored in subdaemons which are per-peer, but very useful for
multi-peer daemons like connectd and gossipd.

Christian Decker 314622028f onchaind: Eliminate a chicken-and-egg problem with msg parsing
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...

Christian Decker fad9a74662 tx: Use the context chainparams to determine the fee asset
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).

Rusty Russell ee3480e56b derive_keyset: don't rotate key for remote iff option_static_remotekey.
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.

Rusty Russell 837e6232c3 common: reduce header differences for DEVELOPER vs non-DEVELOPER.
`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.

Rusty Russell dffe2f516a signature: wrap almost all signatures in struct bitcoin_signature.
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?).

Rusty Russell 5cf34d6618 Remove tal_len, use tal_count() or tal_bytelen().
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.

Rusty Russell c78afa9201 onchaind: use lowball fee instead of donating to miners.
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.

Rusty Russell 1764d6c907 grind_htlc_tx_fee: benchmark.
Takes 15 seconds on my laptop to do the worst-case grind:

	$ onchaind/test/run-grind_feerate 250001
	250001 iterations in 15893 msec = 63574 nsec each

It's not worth optimizing as it's 75% in libsecp:

    29.65%  run-grind_feera  run-grind_feerate  [.] secp256k1_fe_mul_inner
    23.51%  run-grind_feera  run-grind_feerate  [.] secp256k1_fe_sqr_inner

     5.70%  run-grind_feera  run-grind_feerate  [.] Round

Even forcing a compile with -O3 -flto, it's only 13883 msec = 55534 nsec each.
