This is immune to things like clock changes, and has the convenient side-effect that
it will *not* be overridden when we override time for developer purposes.

They are invalid! This is because our BOLT11_FIELD_BYTE_LIMIT is not the limit,
it's one greater than the limit.

Changelog-Fixed: JSON-RPC: `invoice` no longer accepts 640-byte descriptions (it would produce malformed invoices).
The keysend plugin previously used `> 1023` as the cutoff for
description length when inserting an invoice. This was
inconsistent with invoice.c, which enforces the BOLT11 description
field limit defined in `common/bolt11.h`.
This patch switches to using `BOLT11_FIELD_BYTE_LIMIT` directly.
As a result, keysend no longer fails on descriptions between
641–1023 bytes, which previously caused unexpected failures.
A new regression test (`test_keysend_description_size_limit`)
exercises boundary cases just below, at, and above the limit.
Changelog-Fixed: Protocol: `keysend` with descriptions of length 640-1023 bytes fixed.

They were never referenced, and saving the toks is questionable since their
lifetime is not guaranteed to live beyond this call (at least the buffer was
duplicated, but that also assumed it was at the start of the object).

Each header should only include the other headers it needs to compile;
`devtools/reduce-includes.sh */*.h` does this. The C files then need
additional includes if they don't compile.
And remove the entirely useless wire/onion_wire.h, which only serves to include wire/onion_wiregen.h.

Without knowing what method was called, we can't have useful general logging
methods, so go through the pain of adding "const char *method" everywhere,
and add:
1. ignore_and_complete - we're done when jsonrpc returned
2. log_broken_and_complete - we're done, but emit BROKEN log.
3. plugin_broken_cb - if this happens, fail the plugin.

When we used to allow cmd to be NULL, we had to hand the plugin
everywhere. We no longer do.
1. Various jsonrpc_ functions no longer need the plugin arg.
2. send_outreq no longer needs a plugin arg.
3. The init function takes a command, not a plugin.
4. Remove command_deprecated_in_nocmd_ok.

This means we replace p->cmd with an auxillary command after we've
finished, so we have a valid command to use.
It also means we weave `struct command_result` returns back through
all the callers.

This allows us to directly returnan error code based on where we
decided to abort, rather than attemtping to infer it from the parts.

This avoids globals (and means memleak traverses the variables!): we
only change over the test plugin though, to avoid unnecessary churn.

For bolt12, we have blinded paths so we route to the head of the blinded
path, which may not be the same as the final payment destination.
This matters mainly for detecting self-pay.

We have various functions to convert to a string, rename them all so we can
count on fmt_X being the formatter for struct X, and make them all return
`char *`.
Sometimes they existed but were private, sometimes they had a
different name. Most take a pointer, but simple types pass by copy:
short_channel_id, amount_msat and amount_sat.
The following public functions changed:
1. psbt_to_b64 -> fmt_wally_psbt.
2. pubkey_to_hexstr -> fmt_pubkey.
3. short_channel_id_to_str -> fmt_short_channel_id (scid by copy now!)
4. fmt_signature -> fmt_secp256k1_ecdsa_signature
5. fmt_amount_sat/fmt_amount_msat pass copy not pointer, return non-const char *.
6. node_id_to_hexstr -> fmt_node_id

Since it is an optional field in the `listconfigs` output we can't use
the `rpc_scan` mechanism (doesn't handle optionals yet). We'll use
that list of accepted types later to avoid stripping them.
We simply take the first one, and route to the start of that. Then we
append the blinded path to the onion construction.

We were setting it on the root, but that doesn't get handed to

Callers were supposed to call "tlv_fields_valid" after fromwire_tlv,
but few did. Make this the default, and call the underlying function
directly where we want to be more flexible (one place).
This loses the ability to allow misordered fields, or to pass through
*any* even fields. We restore that for special cases in the next
patch.

1. We don't keep a pointer to payments (unlike pay, which keeps a
linked list), so mark it notleak.
2. plugin->our_features is overloaded for "features we want to set" (used by keysend)
and then "features we have". Create a new field, which is cleaner.
