It runs 6 nodes: under valgrind this ends up consuming 5.3 GB RSS. By
stopping nodes between, we peak about 1G RSS.
Measured using:
(while true; do echo $(for i in 4 5 6; do ps uh | tr -s ' ' | cut -d\ -f$i | tally; done); sleep 5; done)&
(Which measures my other processes as well, but that's only about 100M).

This happened in my tal_dump(), and I couldn't see how we ended up
with object having more than one "backtrace". Adding asserts that we
never added a second backtrace didn't trigger.
Finally I wondered if we were tal_steal() backtraces, and sure enough
we do that blinding in one place: libwally wrapping. So fix that.

Do proper refcounting on log prefixes; previously we kept them around,
which is fine, but the extra notleak() and backtrace in developer mode
could get quite heavy (I ended up with 1G of backtraces!). This is
mainly due to creating one on every JSONRPC command, and running
clboss.

Changelog-Fixed: lightningd: remove slow memory leak in DEVELOPER builds.
I noticed that `wallet/db_postgres.c` never actually calls `db_changes_add`.
PostgreSQL arguably has a better replication system (a PostgreSQL cluster)
than what `db_write` hook can offer, so rather than make `db_write` work on
PostgreSQL, just document that it does not actually work there.
ChangeLog-none
Because db->conn is a void *, changing it (from a direct pointer to
a pointer to a pair of pointers) did not break compile if one place hadn't
been update.
The result was a confusing failure: sqlite3 complaining about API misuse,
since the db->conn pointer was not a valid db handle any more.
This is one case where avoiding a void * is hard: we might not even
have the postgresql types, since it might not be installed. But a union
would have been superior here.

ChangeLog-Added: With the `sqlite3://` scheme for `--wallet` option, you can now specify a second file path for real-time database backup by separating it from the main file path with a `:` character.
1. db_col_text becomes db_col_strdup, which is what is usually wanted.
2. db_col_short_channel_id becomes db_col_short_channel_id_str, to emphasize
that it stores in string form. Modern versions should store u64.

This simplistically maps names to numbers, eg:
SELECT foo, bar FROM tbl;
'foo' -> 0
'bar' -> 1
If a statement is too complex for our simple parsing, we treat it as a
single field (which currently it always is).

This surprised me, since the CHANGELOG for [0.8.2] said:
We now announce multiple addresses of the same type, if given. ([3609](https://github.com/ElementsProject/lightning/pull/3609))
But it lied!
Changelog-Fixed: We really do allow providing multiple addresses of the same type.

autotor is older, but statictor is better. Your options are really
"use HiddenServiceDir in torrc" vs "use statictor", with the issue
that statictor requires you to configure Tor for control access by
c-lightning.

October was the date Torv2 is no longer supported by the Tor Project;
it will probably not work at all by next release, so we should remove
it now even though it's not quite the 6 months we prefer for
deprecation cycles.
I still see 110 nodes advertizing Torv2 (vs 10,292 Torv3); we still
parse and display it, we just don't advertize or connect to it.

On some distributions (e.g. Gnu Guix) Python packages are not installed in
some standard directory, rather they are installed in different places and
the `PYTHONPATH` variable is modified to include the different places.
So, we must not use the name `PYTHONPATH` in our `Makefile` since `make`
will replace the `PYTHONPATH` environment variable, preventing e.g.
`tools/generate-wire.py` from finding `python-mako` installed on such
distributions.
