In several places we want to access the first element of an array.
This uses a '[indexnum:xxx]' form which is a bit weird, but works similarly
to the way we specify member matches.

This takes a JSON-style format string, and does intelligent parsing,
removing a lot of boilerplate from code which needs to deal with JSON.

A user reported that it is sometimes cumbersome to search an invoice
based on the payment hash or the bolt11 string in the full list, which
may be required when we don't have the label available.
This adds support for querying / filtering based on the `payment_hash`
or `bolt11` string.
Changelog-Added: JSON-RPC: `listinvoices` can now query for an invoice matching a `payment_hash` or a `bolt11` string, in addition to `label`
I saw this message:
```
lightning_channeld: outstanding taken(): channeld/channeld.c:3087:blinding
lightning_channeld: outstanding taken(): channeld/channeld.c:3087:blinding
lightning_channeld: outstanding taken(): channeld/channeld.c:3087:blinding
```
The caller does take(blinding), but blinding can be NULL. We should
move the code around to do the take() earlier anyway.

This will cause blow ups for v2 multifundchannel attempts with failures,
but allows us to return the expected errors for single-shot
fundchannel attempts.
Error handling is coming, i promise
Since we round down in `amount_tx_fee`, find the change fee as the
difference between what we've already paid and what the combined/total
fee would be if the change weight were also added.
Ideally we'd 'cure' the error and re-attempt, except that if this was a
bitcoin-backend 'failure to broadcast' then it really needs user
intervention to figure out what's wrong -- it's possible that the
peer successfully broadcast the transaction
This makes use of the constant defined in the previous commits to more
accurately detect plaintext, encrypted, and invalid seeds. We now error
on invalid seeds.

This avoids duplication of both logic and error-prone values, such as
the salt. Grouping all hsm encryption logic into a public API will also
allow us to fuzz it.

A fractional satoshi value isn't really useful; rounding up loses
precision but that's why you called "whole satoshi", wasn't it?
Changelog-Changed: pyln-client: Millisatoshi has new method, `to_whole_satoshi`; *rounds value up* to the nearest whole satoshi
We need to use it for the 'df_accepter' plugin, so we get the feerate
correct.

This slightly breaks the API, but still accept the input: we just don't
take it into account anymore.
For `dumponchaindescriptors`, we have to still take the old place of the
`network` parameter into account to not entirely break the API.

This was causing the following error

We were getting bad gossip because some nodes discarded the channel
announcement for being in the future. This is because the node was, at
that time, below the confirmation height. It'd then discard the
followup messages because not preceded by an announcement, and getting
upset about that.
Both my machine and apparently the CI tester machines regularly run
into issues with load on the system, causing timeouts (and
unresponsiveness). The throttler throttles the speed with which new
instances of c-lightning get started to avoid overloading. Since the
plugin used for parallelism when testing spawns multiple processes we
need to lock on the fs. Since we have that file open already, we'll
also write a couple of performance metics to it.
We sometimes have very specific sequences of tx broadcasts and blocks
being generated to confirm them. If the confirmation is missed the
test can completely get out of sync. Make debugging this easier by
logging what we confirmed.
