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.

4dded23cd3 hsmtool: use flag TCSANOW when disabling tty ECHO, fixes rare hang in test_hsm*
No idea why TCSAFLUSH was used, could not find anything in PR comments.
Also cannot explain exactly what causes the problem, but the hang can be reproduced
*with* TCSAFLUSH and not with TCSANOW.

According to termios doc:
TCSANOW
    the change occurs immediately.
TCSAFLUSH
    the change occurs after all output written to the object referred by fd has been
    transmitted, and all input that has been received but not read will be discarded
    before the change is made.

c1f534a159 backtrace: avoid duplicate backtrace objects.
This happened in my tal_dump(), and I couldn't see how we ended up
with object having more than one "backtrace".  Adding asserts that we
never added a second backtrace didn't trigger.

Finally I wondered if we were tal_steal() backtraces, and sure enough
we do that blinding in one place: libwally wrapping.  So fix that.

2f247c7bfb torv2: remove support for advertizing and connecting.
October was the date Torv2 is no longer supported by the Tor Project;
it will probably not work at all by next release, so we should remove
it now even though it's not quite the 6 months we prefer for
deprecation cycles.

I still see 110 nodes advertizing Torv2 (vs 10,292 Torv3); we still
parse and display it, we just don't advertize or connect to it.

prevents sudden feerate changes from overshooting our dust budget)

5356267f15 *: Use new closefrom module from ccan.
This also inadvertently fixes a latent bug: before this patch, in the
`subd` function in `lightningd/subd.c`, we would close `execfail[1]`
*before* doing an `exec`.
We use an EOF on `execfail[1]` as a signal that `exec` succeeded (the
fd is marked CLOEXEC), and otherwise use it to pump `errno` to the
parent.
The intent is that this fd should be kept open until `exec`, at which
point CLOEXEC triggers and close that fd and sends the EOF, *or* if
`exec` fails we can send the `errno` to the parent process vua that
pipe-end.

However, in the previous version, we end up closing that fd *before*
reaching `exec`, either in the loop which `dup2`s passed-in fds (by
overwriting `execfail[1]` with a `dup2`) or in the "close everything"
loop, which does not guard against `execfail[1]`, only
`dev_disconnect_fd`.

20fe5c6ab1 common/json.c: Have json_add_literal *use* len argument.
The current `json_add_literal` does not use its `len` argument, at all:

09c2fef4a4/common/json.c (L1076-L1083)

Which is something of a WTF, why even require the `len` argument if it
is not even used in the function?
This would have been acceptable if it were a callback and the
callback-requiring function passed it in always, but this function is
not intended to be a callback but instead to be called directly.

Existing callers always pass in `strlen(literal)`, so this bug was not
noticed before:
