007a62a369 coin moves: handle ignored outputs
Ignored outputs don't end up in the same 'resolved' pathway as other
tracked outputs do, so we mark them as moved when proposed/broadcast
instead of when resolved (since they'll never flow through as resolved)

4eb1233ccb lightningd: don't report spurious temporary_node_failure on local failures.
I noticed the following in logs for tests/test_connection.py::test_feerate_stress:

```
DEBUG 022d223620a359a47ff7f7ac447c85c46c923da53389221a0054c11c1e3ca31d59-chan#1: Failing HTLC 18446744073709551615 due to peer death

```

This is because it reports the (transient) node_failure error, because
our channel_failure message is incomplete.  Fix this wart up.

0e20e3c5e7 df: rename 'funder' to 'opener'
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.

8cbc0038bc onchaind: a feerate per transaction type
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.

273029f244 wallet: set nLockTime to the tip for withdrawal transactions
This sets the nLockTime to the tip (and accordingly each input's nSequence to
0xfffffffe) for withdrawal transactions.

Even if the anti fee-sniping argument might not be valid until some time yet,
this makes our regular wallet transactions far less distinguishable from
bitcoind's ones since it now defaults to using native Segwit transactions
(like us). Moreover other wallets are likely to implement this (if they
haven't already).

Changelog-Added: wallet: withdrawal transactions now sets nlocktime to the current tip.

7283efa5b5 elements: Add amount_asset to support more than just plain satoshis
Currently the only source for amount_asset is the value getter on a tx output,
and we don't hand it too far around (mainly ignoring it if it isn't the
chain's main currency). Eventually we could bubble them up to the wallet, use
them to select outputs or actually support assets in the channels.

Since we don't hand them around too widely I thought it was ok for them to be
pass-by-value rather than having to allocate them and pass them around by
reference. They're just 41 bytes currently so the overhead should be ok.

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).

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.

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.

5dff67900e tx: Add chainparams when deserializing transactions from wire msgs
This is the other origin, besides `bitcoin_tx`, where we create `bitcoin_tx`

chainparams into the deserialization code since that'd need to change all the
