836c1b805b doc: update c-lightning to Core Lightning almost everywhere.
Mostly comments and docs: some places are actually paths, which
I have avoided changing.  We may migrate them slowly, particularly
when they're user-visible.

2526e804f7 doc: big BOLT update to incorporate warnings language.
We do this (send warnings) in almost all cases anyway, so mainly this
is a textual update, but there are some changes:

1. Send ERROR not WARNING if they send a malformed commitment secret.
2. Send WARNING not ERROR if they get the shutdown_scriptpubkey wrong (vs upfront)
3. Send WARNING not ERROR if they send a bad shutdown_scriptpubkey (e.g. p2pkh in future)
4. Rename some vars 'err' to 'warn' to make it clear we send a warning.

This means test_option_upfront_shutdown_script can be made reliable, too,
and it now warns and doesn't automatically close channel.

3b536400f9 specs: update CSV files.
Regenerate from current BOLTS via `make extract-bolt-csv`

1. The remote_addr field was added manually into peer_wire.csv: this
   needs to be a patch otherwise it vanishes on regen.
2. We never brought into the channel_disabled fields, because it was
   too much hassle (we never actually generate this!).  Do it now.

20392ae526 connectd: restore obs2 onion support.
I removed these prematurely: we *haven't* had a release since
introducing them!

This consists of reverting d15d629b8b
"plugins/fetchinvoice: remove obsolete string-based API." and
plugins/fetchinvoice: remove obsolete string-based
API. "onion_messages: remove obs2 support."

Some minor changes due to updated fromwire_tlv API since they
were removed, but not much.

83ee68ab06 common/tlvstream: put TLV checking back in the generic function.
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.

a770f51d0e tools/generate_wire.py: make functions allocate the TLV.

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

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.

This is from 6e99c5feaf60cb797507d181fe583224309318e9

We renamed the enctlv field to encrypted_recipient_data in the spec, and the
new onion_message is message 513.  We don't handle it until the next patch.

Two renames:
1. blinding_seed -> blinding_point.
2. enctlv -> encrypted_recipient_data.

features only used by our own plugins, we just rename.
