The DB field type has to match the size of the accessor-type, and we had to
split the `REPLACE INTO` and `INSERT INTO OR IGNORE` queries into two
queries (update and insert if not updated) since there is no portable UPSERT
operation, but impact should be minimal.

sqlite3 was forgiving, postgres isn't, so let's make sure we use the strictest
field type possible, relaxing when rewriting.
The commit consists just of the following mapping
- INTEGER -> BIGSERIAL if it is the primary key
- INTEGER -> BIGINT if it is an amount or a reference to a primary key

This was already done in `db_step` but `db_count_changes` and
`db_last_insert_id` also rely on the statement being executed. Furthermore we
now check that the statement was executed before freeing it, so it can't
happen that we dispose of a statement we meant to execute but forgot.
The combination of these could be used to replace the pending_statement
tracking based on lists, since we now make sure to execute all statements and
we use the memleak checker to make sure we don't keep a statement in memory.

sqlite3 will just report 0 for anything that it thinks should be numeric, or
is accessed using a numeric accessor. Postgres does not, so we need to check
for is_null before trying to read it.

sqlite3 doesn't really do any validation whatsoever, and there is no
difference between 64bit and 32bit numbers. Posgtres on the other hand gets
very upset if the size doesn't match.
This commit swaps out handwavy types with the ones that should be there :-)

This was weird right from the start, so we just split the table into integers
and blobs, so each column has a well-defined format. It is also required for
postgres not to cry about explicit casts in the `paramTypes` array.

The first ever query to check if the version DB exists may fail. We allow
this, but we need to restart the DB transaction since postgres fails the
current transaction and rolls back any changes.
This just commits (and fails) and starts a new transaction so the rest of the
migration can continue.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
Needed to change a couple of migrations. The changes are mostly innocuous:
- changing BLOB to TEXT for short_channel_ids which is the correct type
anyway, and sqlite3 treats them the same anyway.
- Use `int` for version since the byte representation is checked by postgres.
- Change anything that is INT, but will be bound to u64 to BIGINT (again
postgres checks these more carefully than sqlite3).
Two migrations were replaced with dummy values, since they are buried deep
enough, and I found no portable way of expressing `strftime()` and `INSERT OR
IGNORE`.

Using a generated identifier with filename and line proved to be brittle since

This avoids having to correlate with listpeers for the most pertinent
information.
This API predates plugins, otherwise we'd have listutxos and listpeers
and this would simply combine them appropriately. Still, it exists so
there's little reason not to make it more friendly.

Allow a user to select the utxo set that will be added to a
transaction, via the `utxos` parameter. Optional.
Format for utxos should be of the form ["txid:vout","..."]
Rather than reaching into data structures, let them register their own
callbacks. This avoids us having to expose "memleak_remove_xxx"
functions, and call them manually.
Under the hood, this is done by having a specially-named tal child of
the thing we want to assist, containing the callback.

It's better to let the driver decide when and how to expand. It can then

We now have a much stronger consistency check from the combination of
transaction wrapping, tal memory leak detection. Tramsaction wrapping ensures
that each statement is executed before the transaction is committed. The
commit is also driven by the `io_loop`, which means that it is no longer
possible for us to have statements outside of transactions and transactions
are guaranteed to commit at the round's end.
By adding the tal-awareness we can also get a much better indication as to
whether we have un-freed statements flying around, which we can test at the
end of the round as well.

This is likely the last part we need to completely encapsulate the part of the
sqlite3 API that we were using. Like the `db_count_changes` call I decided to
pass in the `struct db_stmt` since really they refer to the statement that was
executed and not the db.

These are based on top of the basic column access functions, and act as a
small type-safe wrapper, that also does a bit of validation.

This has a slight side-effect of removing the actual begin and commit
statements from the `db_write` hooks, but they are mostly redundant anyway (no
harm in grouping pre-init statements into one transaction, and we know that
each post-init call is supposed to be wrapped anyway).

For some of the query methods in the next step we need to have an idea of
