Just applied the same suppression as rusty in:
6635fe12e4 (Rusty Russell 2020-05-15 15:57:29 +0930 146)
/* cppcheck-suppress uninitvar - false positive on f1->bits */
My cppcheck was complaining about the same issue in the following functions.
I wonder why travis does not care though.
Changelog-None
1. One place returned false instead of -1.
2. The names implied it returned a bool, and it doesn't.
Fix both, and curse C's loose typing a little.

There's a spec rule about only ever sending a correctly sized
feature-bits, so as a precaution we have `clear_feature_bit` correctly
resize when a bit is cleared.
libwally has a quirk where the finalize method will fail to 'completely'
finalize an input's parts if either the final_scriptsig or
final_redeemscript fields are set
since we manually set the final_witness stack here, we also need to
fully finalize the redeemscript -> final_scriptsig here as well.
And make caller of json_stream_forward_change_id use it, since
we're going to reuse that.
Also call json_out_finished here, so next object doesn't have a ","
prepended.

Note that check-whitespace and check-bolt already do this, so we
can eliminate redundant lines in common/Makefile and bitcoin/Makefile.
We also include the plugin headers in ALL_C_HEADERS so they get
checked.

This:
- Allows `.*btc` amounts (without post-decimal)
- Avoids creating decimals when amount is 0 btc
- Corrects our handling of the suffixes (memeqstr would
sometimes return false because of null-termination)
Changelog-Fixed: We are now able to parse any amount string (XXXmsat, XX.XXXbtc, ..) we create.

Instead of a boutique message, use a "real" channel_announcement for
private channels (with fake sigs and pubkeys). This makes it far
easier for gossmap to handle local channels.
Backwards compatible update, since we update old stores.
We also fix devtools/dump-gossipstore to know about the tombstone markers.
Since we increment our channel_announce count for local channels now,
the stats in the tests changed too.

We were always ordering heap by distance, not score (which are different
if we are routing by cheapest, not shortest!).
This simplifies our callbacks, too.

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.
There are 3 commands for opening a channel with dualfunding.
`openchannel_init` is the first of these.
It initializes the open-channel dialog, and stops once we've run out of
updates (input/outputs) to send to the peer.
We force use of tal_wally_start/tal_wally_end around every wally
allocation, and with "end" make the caller choose where to reparent
everything.
This is particularly powerful where we allocate a tx or a psbt: we
want that tx or psbt to be the parent of the other allocations, so
this way we can reparent the tx or psbt, then reparent everything
else onto it.
Implementing psbt_finalize (which uses a behavior flag antipattern)
was tricky, so I ended up splitting that into 'psbt_finalize' and
'psbt_final_tx', which I think also makes the callers clearer.

1. Rename memleak_enter_allocations to memleak_find_allocations.
2. Unify scanning for pointers into memleak_remove_region / memleak_remove_pointer.
3. Document the functions.

The next patch perturbed things enough that we suddenly started
getting (with --track-origins=yes):

This is because there is uninitialized padding at the end of struct
peer_state.
