8c14c39c7e onchaind: Adjust the sweep target deadline for fee estimation
We used to always target `now() + 300`, which ends up never really
confirming, as the fee estimate bumps into the min-relay-fee
limit. With this commit we set an absolute target of 2 weeks, and a
linear fee rampup, until we are at T-2h, at which point we just stick
with the estimate, and try with this increased feerate to try and get
the sweep confirmed.

This ought to make RBF transactions much more efficient for closing
channels.

Changelog-Fixed onchaind: The sweep deadline for to_us outputs would be reset on each restart of the subdaemon. Now the deadline is absolute in terms of the close height.

7b3a4799db coin-moves: when a splice confirms, send a channel_closed event
We weren't properly notifying that a channel output has been spent in
the case of it being spent in a splice. This fixes the notification side
of the equation, however there's still some issues remaining for the
bookkeeper side (to come).

Changelog-Fixed: We now send a `coin_movement` notification for splice confirmations of channel funding outpoint spends.

a1fdeee76b Makefile: clean up install path handling.
We had some weird code to try to do relative paths.  Instead, use absolute
ones and keep life simple.  Also rename "daemon_dir" to the clearer
"subdaemon_dir" as that's what it's used for.

We now need special magic to do "installcheck", which is a bit awkward,
but at least it's contained.

2e06d814e5 lightningd: fix false positive in leak detection.
We ask each channeld to report its leaks, and keep a refcount of how
many are outstanding.  When the channeld replies, or dies, we decrement
the count in a destructor.

But if the last channeld we're waiting for dies, we can call the
destructor in an unexpected place, and thus run leak detection when
we were partway through some operation, which gives a false positive.
Here's a backtrace showing it:

401d85fce0 lightningd: make invreq metdata deterministic, not random for recurring invoices.
This is going to allow us to move it out from lightingd into plugin,
easily.  It's legal because the combination of offer id and label must
be unique (with recurrence, we use the same metadata anyay, since they
want to correlate with prior payments anyway).

We already broke recurrence in this PR, so we don't need another note to say
we're changing the key derivation.

Unlike "sendonionmessage" which instructs us to send to a peer, this
