572942c783 psbt: use DER encoded + sighash byte for PSBT_IN_PARTIAL_SIG items
Per BIP-0171, the signature map is of pubkey to "The signature as would
be pushed to the stack from a scriptSig or witness".

Fixes 5298

Changelog-Fixed: PSBT: Fix signature encoding to comply with BIP-0171.

b359a24772 cln-plugin: Handle --help invocations better
We now have ternary outcomes for `Builder.configure()` and
`Builder.start()`:

 - Ok(Some(p)) means we were configured correctly, and can continue
   with our work normally
 - Ok(None) means that `lightningd` was invoked with `--help`, we
   weren't configured (which is not an error since the `lightningd` just
   implicitly told us to shut down) and user code should clean up and
   exit as well
 - Err(e) something went wrong, user code may report an error and exit.

bf4d9e30d2 fundpsbt: deprecate reserve=true/false usage.
Make it always a number; this makes the JSON request specification
simpler.  We allowed a number since v0.10.1.

(reserve=True is the default anyway, so usually it can be omitted:
reserve=False becomes reserve=0).

Changelog-Deprecated: JSON-RPC: `fundpsbt`/`utxopsbt` `reserve` must be a number, not bool (for `true` use 72/don't specify, for `false` use 0).  Numbers have been allowed since v0.10.1.

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.

65be18d355 memleak: handle libwally allocations better.
Things allocated by libwally all get the tal_name "wally_tal",
which cost me a few hours trying to find a leak.

In the case where we're making one of the allocations the parent
of the others (e.g. a wally_psbt), we can do better: supply a name
for the tal_wally_end().

So I add a new tal_wally_end_onto() which does the standard
tal_steal() trick, and also changes the (typechecked!) name.
