We have them split over common/param.c, common/json.c,
common/json_helpers.c, common/json_tok.c and common/json_stream.c.
Change that to:
* common/json_parse (all the json_to_xxx routines)
* common/json_parse_simple (simplest the json parsing routines, for cli too)
* common/json_stream (all the json_add_xxx routines)
* common/json_param (all the param and param_xxx routines)

We had json_add_amount_msat_only(), which was designed to be used to
print out msat fields, if we had sats.
However, we misused it, so split it into the three different cases:
1. json_add_amount_sat_msat: We are using it correctly, with a field called
xxx_msat.
2. json_add_amount_sats_deprecated: We were using it wrong, so deprecate
the old field and create a new one which does end in _msat.
3. json_add_sats: we were using it to hand sats as a JSON parameter to an
interface, where "XXXsat".

And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).
config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

Users are more upset recently with the cost of unilateral closes
than they are the risk of being cheated. While we complete our
anchor implementation so we can use low fees there, let's
get less aggressive (we already have 34 or 18 blocks to close
in the worst case).
The changes are:
- Commit transactions were "2 CONSERVATIVE" now "6 ECONOMICAL".
- HTLC resolution txs were "3 CONSERVATIVE" now "6 ECONOMICAL".
- Penalty txs were "3 CONSERVATIVE" now "12 ECONOMICAL".
- Normal txs were "4 ECONOMICAL" now "12 ECONOMICAL".
There can be no perfect levels, but we have had understandable
complaints recently about how high our default fee levels are.
Changelog-Changed: Protocol: channel feerates reduced to bitcoind's "6 block ECONOMICAL" rate.

Changelog-Changed: JSON-RPC: If bitcoind won't give a fee estimate in regtest, use minimum.
This makes for more useful errors. It prints where it was up to in
the guide, but doesn't print the entire JSON it's scanning.

We're rarely in a hurry here, and bitcoind is aggressive with fees.
You can always spend this output if you really have to, using CPFP.

Changelog-Changed: Protocol: mutual closing feerate reduced to "slow" to avoid overpaying.
Changelog-Deprecated: plugin: `bcli` replacements should note that `sendrawtransaction` now has a second required Boolean argument, `allowhighfees`, which if `true`, means ignore any fee limits and just broadcast the transaction. Use `--deprecated-apis` to use older `bcli` replacement plugins that only support a single argument.
We were using `tal_fmt` to truncate off the last byte of the
response (newline), which required an allocation, a call to `vsnprintf` and a
copy of the block contents. This being >2MB in size on mainnet was rather
expensive.
We now just signal the end of the string by overwriting the trailing newline,
and stealing directly onto the result.
We've had problems with blocksonly in the past and bitcoind still allows
to use outdated (thus potentially dangerous estimates) while running
bitcoin with -blocksonly.
ZmnSCPxj mentionned that we still don't document this, but i figured
that in this specific case an explicit check and error seems preferable.
Changelog-Added: We now explicitly check at startup that our default Bitcoin backend (bitcoind) does relay transactions.

This allows us to kill two birds with one stone: once connected, we use
the output of the successful call to do some sanity checks (only
checking the version for now, but more are yet to come!).

Changelog-Fixed: plugin: `bcli` no longer logs a harmless warning about being unable to connect to the JSON-RPC interface.
Changelog-Added: plugin: Plugins can opt out of having an RPC connection automatically initialized on startup.
We did not take the value of --commit-fee into account : this removes
the unused option from lightningd and instead registers it in bcli,
where we set the actual feerate of commitment transactions. This also
corrects the documentation.

A CONSERVATIVE/3 target for them.
Some noisy changes to the tests as we had to update the estimatesmartfee
mock.
Changelog-Changed: We now use a higher feerate for resolving onchain HTLCs and for penalty transactions
This is also taken and adapted from lightningd/bitcoind.
The call to 'getblockchaininfo' is replaced by 'echo' as we don't
make use of the result and the former can sometimes be slow (e.g. on
IBD).
Most is taken from lightningd/bitcoind and adapted. This currently
exposes 5 commands:
- `getchaininfo`, currently called at startup to check the network and
whether we are on IBD.
- `getrawblockbyheight`, which basically does the `getblockhash` +
`getblock` trick.
- `getfeerate`
- `sendrawtransaction`
- `getutxout`, used to gather infos about an output and currently used by
`getfilteredblock` in `lightningd/bitcoind`.
