Note: won't work with grpc (or probably other tools), since the output
is different. But good for testing.

Changelog-Added: Config: option `xpay-handle-pay` can be used to call xpay when pay is used in many cases (but output is different from pay!)
Because we initalized plugin->io_rpc_conn *after* calling plugin->init,
send_outreq would do a (harmless, in our case) wakeup on an uninitialized address:
```
==1164079== Conditional jump or move depends on uninitialised value(s)
==1164079== at 0x1628FC: backend_wake (poll.c:227)
==1164079== by 0x160B98: io_wake (io.c:384)
==1164079== by 0x1160A8: ld_rpc_send (libplugin.c:255)
==1164079== by 0x1187E0: send_outreq (libplugin.c:1099)
==1164079== by 0x115041: init (xpay.c:1620)
```
Solution is simple: set plugin->io_rpc_conn to NULL, and don't wake it in this case.

fail->msg can be NULL for local failures (the error message itself is more informative
in this case). Use the generic "something went wrong" message.

Changelog-Changed: Wallet: Taproot addresses are used for unilateral-close change addresses.
It only works on BOLT11, and has long been replaced by the more
generic "decode".
Removing it will stop the confusion!
(Note: documentation claims it was introduced in 23.08, but that was
wrong, as it's been in CLN since the beginning).

Changelog-Deprecated: JSON-RPC: `decodepay`: use `decode`.

Looking at the logs (and comparing a successful run), it seems the connect happens before
the connect_stream is ready, so we miss it:

Since wait_for_onchaind_tx doesn't actually wait for the call to bitcoind to
return, we have a race in checking if the txid is in the mempool. Fix this
by making wait_for_onchaind_tx actually wait for the response (except for delayed txs!).
