We previously tried to use the commitment tx to create an initial
feerate range, then refine it as we look at each HTLC tx. This was
wrong, because the commitment tx can underpay fees (if it can't afford
it), and our estimate of the maximum possible feerate would be too low.
Now, we only have two fees we need to figure out: HTLC timeout txs and
HTLC success txs, so simply grind them on first use.

These are basic instructions that lead to the build process completing without error (after a known error occurs and is rectified). For now, the final results are untested.
In particular, the main daemon and subdaemons share the backtrace code,
with hooks for logging.
The daemon hook inserts the io_poll override, which means we no longer
need io_debug.[ch]. Though most daemons don't need it, they still link
against ccan/io, so it's harmess (suggested by @ZmnSCPxj).
This was tested manually to make sure we get backtraces still.

I didn't convert all tests: they can still use a standalone context.
It's just marginally more efficient to share the libwally one for all
our daemons which link against it anyway.

This may be causing #1280, since with `--daemon` the DB is being reopened
without enabling the foreign key relations and hence the delete cascades.

If we only remember the actions that added channels then we'd restore them when
re-reading the gossip_store, so put a tombstone in there to remember to delete
it. These will be cleared upon re-writing the store since the announcements wont
be written anymore.

In the next commit we remove channels whose outpoint was spent from our network
view, so checking for it will not work anymore.

This was a tricky one to find, it turns out that some nodes are sending
node_announcements even if they don't have a channel announced yet. If they are
a peer and the channel is currently verifying then we'll have a local channel in
the network view, hence accept the node_announcement, but when replaying, the
node_announcement will be replayed and we won't have a channel yet. This just
skips node_announcements, which is always safe.

The overflow check `mul_overflows_s64(int64_t, int64_t)` overflows.
Since this is an signed integer overflow this triggers UB, which
in turn means that we cannot trust the check.
Luckily mul_overflows_s64(int64_t, int64_t) is unused. Removing it.
This is necessary since we have onchaind tell us about the
their_unilateral/to_us output, after it is already in a block.
