7f2b332021 connectd: implement connection timeout (60 seconds).
This is simple, and we now can multifundchannel to every node on testnet
(one simply hangs once we connect).

Changelog-Fixed: Protocol: We now hang up if peer doesn't respond to init message after 60 seconds.

bc5a817100 elements: convenience methods for dealing with assets
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.

2e9c387f45 coin_moves: update withdrawal logic to account for 'variable owner' txs
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

b0c9059602 tools/generate-wire: no more lonely messages!
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!

3b4a06f52b common: generalize ecdh function.
common/onion is going to need to use this for the case where it finds a blinding
seed inside the TLV.  But how it does ecdh is daemon-specific.

We already had this problem for devtools/gossipwith, which supplied a
special hsm_do_ecdh().  This just makes it more general.

So we create a generic ecdh() interface, with a specific implementation
which subdaemons and lightningd can use.

This will help with the next patch, where we wean off using a global
