4cfd972407 common/blindedpath: expose API at a lower level.
We actually want lightningd to create these, since it wants to put the
path_id secret in the last element.  So best API is actually a generic
one, rather than separate APIs to create first and last ones.

And really, the more explicit initialization makes the users clearer.

53e40c4380 common/blindedpath: generalize routines.
We're going to share them for onion messages as well as for blinded
payments.

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.

b3af5f5a2c spec: import latest onionmessage spec, based on routeblinding.
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.

We don't do a compat cycle for our JSON APIs for these experimental
features only used by our own plugins, we just rename.

b74848f6f6 common: remove support for pre v0.10.2 onionmessages.
Temporarily disable sendpay_blinding test which uses obsolete onionmsg;
there's still some debate on the PR about how blinded HTLCs will work.
