I was wondering why TAGS was missing some functions, and finally
tracked it down: PRINTF_FMT() confuses etags if it's at the start
of a function, and it ignores the rest of the file.
So we put PRINTF_FMT at the end, but that doesn't work for
*definitions*, only *declarations*. So we remove it from definitions
and add gratuitous declarations in the few static places.1

I'm not sure what went wrong, but the first RC I cut had some trouble
with the tag being picked up with `git describe`, I think it was missing
a 'tag message'. I'm not sure what caused this.
This commit breaks up the first git tag procedure to have the releaser
verify that the tag command works as intended (and sensitizes them to
checking this for subsequent release cuts, if necessary)
Feerate changes are asymmetric, as they can only be sent by the funder.
For FUNDER, the remote feerate is set when upon send of
commitment_signed, and the local feerate is set on receipt of
revoke_and_ack.
For non-funder, the local feerate is set on receipt of
commitment_signed, and the remote feerate set on send of
revoke_and_ack. In our code, these two happen together.
channeld gets this right, but lightningd ignored the funder/fundee
distinction, and as a result, receipt of a commitment_signed by the
funder altered fees in the database. If there was a reconnection
event or restart, then these (incorrect) values would be used, causing
us to complain about a 'Bad commit_sig signature' and close the
channel.

A 'Bad commit_sig signature' was reported by @Javier on Telegram and
@DarthCoin. This was between two c-lightning peers, so definitely our fault.
Analysis of this message revealed the signature was using the wrong
feerate. I finally managed to make a test case which triggered this.

Whenever we have multi-connected nodes, out-of-order gossip is possible.
In particular, if a node_announcement is 1 second fresher than the
channel_announcement, a timestamp_filter might get one and not the
other.

The case where this is needed is when the wallet had a forwarded payment
somewhere between commits 66a47d2 (which started tracking forwardings) and
d901304 (which added the `received_time` column). This just emulates the
behavior of sqlite3 for postgres as well.

Checking on whether we access a null field is ok, but should we crash right
away? Probably not. This reduces the access to a warning on sqlite3 and let's
it continue. We can look for occurences and fix them as they come up and then
re-arm the asserts once we addressed all cases.
Asking for the last few blocks was logical, but my node is missing
most gossip in practice.
For the moment, simply ask a peer for every channel it knows, once
we're started up.

When probing, no point probing for before lightning became cool. Current
logic means we often probe below block 500,000, and think things are OK
because there are no short_channel_ids.

We were using `i` as index variable in two nested loops. This works as long as
the DNS seed resolves to a single address, but will crash if the node has both
an A as well as an AAAA entry, at which point we'll try to index the hostname
without a matching entry.

We were implicitly relying on sqlite3 behavior that returns the zero-value for
nulled fields when accessing them. This adds the same behavior explicitly to
the DB abstraction in order to reduce `db_column_is_null` checks in the logic,
but still make it evident what is happening here.
