Rounds out the application of `upfront_shutdown_script`, allowing
an accepting node to specify a close_to address.
Prior to this, only the opening node could specify one.

This simplifies our tests, too, since we don't need a magic option to
enable io logging in subdaemons.
Note that test_bad_onion still takes too long, due to a separate minor
bug, so that's marked and left dev-only for now.

1. Printed form is always "[<nodeid>-]<prefix>: <string>"
2. "jcon fd %i" becomes "jsonrpc #%i".
3. "jsonrpc" log is only used once, and is removed.
4. "database" log prefix is use for db accesses.
5. "lightningd(%i)" becomes simply "lightningd" without the pid.
6. The "lightningd_" prefix is stripped from subd log prefixes, and pid removed.

Changelog-changed: Logging: formatting made uniform: [NODEID-]SUBSYSTEM: MESSAGE
Changelog-removed: `lightning_` prefixes removed from subdaemon names, including in listpeers `owner` field.
A log can have a default node_id, which can be overridden on a per-entry
basis. This changes the format of logging, so some tests need rework.

A long time ago (93dcd5fed7), I
simplified the htlc reload code so it adjusted the amounts for HTLCs
in id order. As we presumably allowed them to be added in that order,
this avoided special-casing overflow (which was about to deliberately
be made harder by the new amount_msat code).
Unfortunately, htlc id order is not canonical, since htlc ids are
assigned consecutively in both directions! Concretely, we can have two HTLCs:
HTLC #0 LOCAL->REMOTE: 500,000,000 msat, state RCVD_REMOVE_REVOCATION
HTLC #0 REMOTE->LOCAL: 10,000 msat, state SENT_ADD_COMMIT
On a new remote-funded channel, in which we have 0 balance, these
commits *only* work in this order. Sorting by HTLC ID is not enough!
In fact, we'd have to worry about redemption order as well, as that
matters.
So, regretfully, we offset the balances halfway to UINT64_MAX, then check
they didn't underflow at the end. This loses us this one sanity check,
but that's probably OK.

Feerate changes are asymmetric, as they can only be sent by the funder.
For FUNDER, the remote feerate is set when upon send of
commitment_signed, and the local feerate is set on receipt of
revoke_and_ack.
For non-funder, the local feerate is set on receipt of
commitment_signed, and the remote feerate set on send of
revoke_and_ack. In our code, these two happen together.
channeld gets this right, but lightningd ignored the funder/fundee
distinction, and as a result, receipt of a commitment_signed by the
funder altered fees in the database. If there was a reconnection
event or restart, then these (incorrect) values would be used, causing
us to complain about a 'Bad commit_sig signature' and close the
channel.

A 'Bad commit_sig signature' was reported by @Javier on Telegram and
@DarthCoin. This was between two c-lightning peers, so definitely our fault.
Analysis of this message revealed the signature was using the wrong
feerate. I finally managed to make a test case which triggered this.

This is mainly an internal-only change, especially since we don't
offer any globalfeatures.
However, LND (as of next release) will offer global features, and also
expect option_static_remotekey to be a *global* feature. So we send
our (merged) feature bitset as both global and local in init, and fold
those bitsets together when we get an init msg.

The test was implicitly relying on us selecting the larger output and then not
touching the smaller, leaving it there for the final `withdraw` to claim. This
ordering of UTXOs is not guaranteed, and in particular can fail when switching
DB backends. To stabilize we just need to make sure to select the change
output as well.
It's generally clearer to have simple hardcoded numbers with an
#if DEVELOPER around it, than apparent variables which aren't, really.
Interestingly, our pruning test was always kinda broken: we have to pass
two cycles, since l2 will refresh the channel once to avoid pruning.
Do the more obvious thing, and cut the network in half and check that
l1 and l3 time out.

After switching to a plugin, we verify that we can fund a channel
before we check to contact a peer. We'll need to have a funded wallet
to pass the check in this test that verifies that 'fundchannel' cannot
be called for a peer after fundchannel_start is.
For now, we can't fully ensure that the broadcast was catched from a third pary. Only when the transaction (broadcast by a third pary) is onchain, we can catch it.
