Fixes 32-bit builds:

67e43ea868 renepay: clean up ARC_ADDITIONAL_BITS.
It's expressed in bits, but really it's clearer as a quantity, given
how it's used.

b793dc9224 renepay: implement an alternative to a union with bitsets.
This was actually relying on little-endian; if we want this, we need to be explicit.

3024afe524 renepay: more cleanups
- adopt "const <type> *"convention
- remove use_shadow option for some pyln tests
- show prob. information of flows into paynotes
- show prob. of success of entire payment flow in paynotes
- minflow: We were not releasing the memory of flow arrays when replacing
  them with a new canditate.
- use memleak_scan_obj in memleak_check
- replace u64 with size_t

b5da85e85d plugins/renepay/dijkstra: improve API to remove global.
The global is an *internal* hack because dijkstra_item_mover doesn't
take a context arg!  It should be used with care.

Easy, since all the accessors exist: we just hand in the struct dijkstra.

79486c1e3b renepay: fixups after comments
- remove internal gheap checks
- add check for arc_t.chanidx overflow
- remove outdated comments
- check the delta flow bounds before augmenting along a path
- get_flow_paths uses a dynamic tal array instead of a list.
- fix a unit test that depended on the order of returned flows
- fix bug: lightnind doesn't like if I reuse the partid of a failed
  flow, therefore use a higher partid than any of the previous attempts.
- plugin_err instead of LOG_BROKEN if sendpay fails and we cannot get a
  an error code.
- fix wrong comments.
- remove the background timer.
- This is a bugfix. Previous to this the MCF network was built using the
knowledge of the min and max liquidity but it didn't take into account
pending HTLCs.
- Also remove the min_prob_success option but hardcode a 90% value.

Removing some options that are not relevant to the user, they're kept
for developer mode only:
- base_fee_penalty
- min_prob_success
- prob_cost_factor
- remove heap.h, not used
