Rusty Russell 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.

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

Rusty Russell 35e3c1866e common: generalize extract_channel_id().
connectd is going to end up using this do demux; make it fast and complete.

Fixing this reveals a problem in openingd: it now extracts the channel_id
from funding_signed (which is where we transition off the temporary), and
gets upset.  So fix that.

Rusty Russell 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.

Rusty Russell 4c63fedce9 test: make an onionmessage test vector.
This builds on the enctlv vectors, but actually goes all the way
to creating a modern onionmessage.

Thanks to Thomas H for corrections!

Rusty Russell e02e0a197d common/test/run-blindedpath_enctlv: use modern functions to create test vector.
And include the final destination enctlv.

Rusty Russell 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.

Yes, we changed the spec again.  Hopefully for the last time!
