In a couple of places we accept arrays of strings and don't validate
them. If we forward them, e.g., call a JSON-RPC method from the
plugin, we end up embedding the unverified string in the JSON-RPC
call without escaping, which then leads to invalid JSON being passed
on.
This at least partially causes #4238
This is vital for calculating merkle trees; I previously used
towire+fromwire to get this!
Requires generation change so we can magic the ARRAY_SIZE var (the C
pre-processor can't uppercase things).

When we support bolt12, this won't exist. We only need min_final_cltv_expiry,
routes and features, so put them into struct payment explicitly.
We move the default final ctlv out to the caller, too, which is clearer.
e.g. keysend was using this value, but it was hard to tell.

Needed for v2 of channel opens, where the minimum weight is 110; a
'simple utxo' (sig + key) weighs in at 107, so we a need a way to
establish a floor for this case.
Changelog-Added: JSON-RPC: fundpsbt/utxopsbt have new param, `min_witness_utxo`, which sets a floor for the weight calculation of an added input
Avoids much cut & paste. Some tests don't need any of it, but most
want at least some of this infrastructure.

We already do some sanity checks, add this one.

Changelog-Changed: JSON-RPC: invalid UTF-8 strings now rejected.
We don't have a problem with them, but callers may; easier to reject bad
UTF8 here than let the caller fail when it tries to parse output.

we only want to sign the inputs that we've reserved via utxopsbt or
fundpsbt. we mark them with a flag (reusing the now defunct max-len
flag is fine), then look for inputs with that flag to pass to signonly
Just applied the same suppression as rusty in:
6635fe12e4 (Rusty Russell 2020-05-15 15:57:29 +0930 146)
/* cppcheck-suppress uninitvar - false positive on f1->bits */
My cppcheck was complaining about the same issue in the following functions.
I wonder why travis does not care though.
Changelog-None
1. One place returned false instead of -1.
2. The names implied it returned a bool, and it doesn't.
Fix both, and curse C's loose typing a little.

There's a spec rule about only ever sending a correctly sized
feature-bits, so as a precaution we have `clear_feature_bit` correctly
resize when a bit is cleared.
libwally has a quirk where the finalize method will fail to 'completely'
finalize an input's parts if either the final_scriptsig or
final_redeemscript fields are set
since we manually set the final_witness stack here, we also need to
fully finalize the redeemscript -> final_scriptsig here as well.
And make caller of json_stream_forward_change_id use it, since
we're going to reuse that.
Also call json_out_finished here, so next object doesn't have a ","
prepended.

Note that check-whitespace and check-bolt already do this, so we
can eliminate redundant lines in common/Makefile and bitcoin/Makefile.
We also include the plugin headers in ALL_C_HEADERS so they get
checked.

This:
- Allows `.*btc` amounts (without post-decimal)
- Avoids creating decimals when amount is 0 btc
- Corrects our handling of the suffixes (memeqstr would
sometimes return false because of null-termination)
Changelog-Fixed: We are now able to parse any amount string (XXXmsat, XX.XXXbtc, ..) we create.
