a770f51d0e tools/generate_wire.py: make functions allocate the TLV.
Requiring the caller to allocate them is ugly, and differs from
other types.

This means we need a context arg if we don't have one already.

fa0c29f959 tools/generate_wire.py: tlvs should start with tlv_
No more "towire_offer", but "towire_tlv_offer".

This means we double-up on the unfortunately-named `tlv_payload` inside
the onion, but we should rename that in the spec when we remove
old payloads.

In particular, this changes the name of a field in invoice_request:

4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
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.

e7b263304e lightningd: Send updated onion spec messages.
It's very similar to the previous, but there are a few changes:

1. The enctlv fields are numbered differently.
2. The message itself is a different number.

The onionmsg_path type is the same, however, so we keep that constant
at least.

The result is a lot of cut & paste, but we will delete the old one
next release.

2112f4fd8e fetchinvoice: include send in path, use pubkeys.
We had sent->path be a list of node_ids, but it makes more sense as
pubkeys so we can avoid conversion.  Also, I find it easier to think
about (especially creating backwards paths) if we include *ourselves*
as the first element in the path.

6aa520bb9b lightningd: remove sendonionmesage parity hack.
offers contain an x-only pubkey: to route to them to need to know the
02 vs 03 prefix.  If they're in the gossmap it's easy, but if they're
a directly-connected peer it's harder.  We used to have
sendonionmessage tweak the key if it found a peer with the matching
key, but this was always a hack.

It turns out that we try to connect to the node anyway, which is
a noop if it's already connected.  So try connecting to the other
parity if the first one fails.

Also, this registers when we fail to connect, and returns an error
rather than waiting for timeout.

a29847f0c6 DEVELOPER: allow fetchinvoice to force they payer_secret.
We usually assume we're fetching an invoice we are going to pay, so we
look up the previous payment for the payer key, and other sanity
checks.

This adds a developer option to fetchinvoice, which allows it to force

checks.
