595fbd2a19 createinvoice: make a minimal blinded "path" in bolt12 invoice if none presented.
The "path" is just a message to ourselves.  This meets the minimal
requirement for bolt12 invoices: that there be a blinded path (at
least so we can use the path_id inside in place of "payment_secret").

We expose the method to make this path_id to a common routine: offers
will need this for generating more sophisticated paths.

36a29fbfbc lightningd/json.h: remove.
There are hardly any lightningd-specific JSON functions: all that's left
are the feerate ones, and there's already a comment that we should have
a lightningd/feerate.h.

401f1debc5 common: clean up json routine locations.
We have them split over common/param.c, common/json.c,
common/json_helpers.c, common/json_tok.c and common/json_stream.c.

Change that to:
* common/json_parse (all the json_to_xxx routines)
* common/json_parse_simple (simplest the json parsing routines, for cli too)
* common/json_stream (all the json_add_xxx routines)
* common/json_param (all the param and param_xxx routines)

4f12ff0967 Makefile: add $(LIGHTNINGD_SRC_NOHDR) to $(ALL_C_SOURCES) for "make clean" to work properly
"make clean" removes all object files listed in $(ALL_OBJS), which is derived from $(ALL_C_SOURCES).
Source files in $(LIGHTNINGD_SRC_NOHDR) are missing from $(ALL_C_SOURCES) therefore some object files are not removed by "make clean".

4508584b21 dualfund: rearrange things so that the wire-dependent calls are separate
There's a few structs/wire calls that only exist under experimental features.
These were in a common file that was shared/used a bunch of places but
this causes problems. Here we move one of the problematic methods back
into `openingd`, as it's only used locally and then isolate the
references to the `witness_stack` in a new `common/psbt_internal` file.

This lets us remove the iff EXP_FEATURES inclusion switches in most of
the Makefiles.

I got a corrupt file, which looked like multiple concurrent attempts

Also move into plugins/ where it logically belongs.

83298c030a wallet: switch over to withdraw in module, remove lots of unused code.
This removes the reservation cleanup at startup, too, now they're all
using 'reserved_til'.

This changes test_withdraw, since it asserted that outputs were marked
spent as soon as we broadcast a transaction: now they're reserved until
it's mined.  Similarly, test_addfunds_from_block assumed we'd see funds
as soon as we broadcast the tx.
