522457a12b connectd, gossipd, pay, bcli: use timemono when solely measuring duration for timeouts.
This is immune to things like clock changes, and has the convenient side-effect that
it will *not* be overridden when we override time for developer purposes.

dd7cc71b38 plugins: remove unused json_buffer / json_toks members from libplugin-pay.
They were never referenced, and saving the toks is questionable since their
lifetime is not guaranteed to live beyond this call (at least the buffer was
duplicated, but that also assumed it was at the start of the object).

f6a4e79420 global: remove unnecessary includes from headers.
Each header should only include the other headers it needs to compile;
`devtools/reduce-includes.sh */*.h` does this.  The C files then need
additional includes if they don't compile.

And remove the entirely useless wire/onion_wire.h, which only serves to include wire/onion_wiregen.h.

c797b6fb20 libplugin: add method string to jsonrpc callbacks, implement generic helpers.
Without knowing what method was called, we can't have useful general logging
methods, so go through the pain of adding "const char *method" everywhere,
and add:

1. ignore_and_complete - we're done when jsonrpc returned
2. log_broken_and_complete - we're done, but emit BROKEN log.
3. plugin_broken_cb - if this happens, fail the plugin.

8e9f71ff85 libplugin: pay now emits channel_hint as we learn about the net
The `pay` plugin, as well as other plugins making use of the tree-pay
executor, will now emit their observations as they see them. The
notifications are sent on the `channel_hint_updated` topic, and any
subscriber will get them.

We also added a `timestamp` to the `struct channel_hint`, as these
observations now outlive the `pay` call, and have to be attenuated /
relaxed as they age, until we can eliminate them completely (when the
restriction is equal to the structural information gathered from the
gossip).

ca1b469c1a plugin/pay: Handle paying to blinded path starting with us.
Ideally, we would be able to submit a payment exactly as an incoming
HTLC would, but our forwarding and decoding logic is currently very
much tied to the HTLC.  It would be wonderful to detach that and
have an "injectonion" interface which was unwrapped like any other
(see "injectonionmessage") which would handle self-pay without any
special paths.

Since I'm not prepared to rewrite that all now, instead we use an
interface to decrypt the first hop if it's us, and use the remainder
of the blinded path.

Changelog-Fixed: plugins: pay can now pay a bolt12 invoice even if we, ourselves, are the head of the blinded path within it.
