This patch adds a channel_id parameter to allow for specifying
channels that are lacking a short_channel_id.
Useful in the case where a peer has 1) multiple channels (ONCHAIN etc)
and 2) a channel where the funding transaction hasn't been
broadcast/mined.
Command format: close id [unilateraltimeout] [destination]
Close the channel with peer {id}, forcing a unilateral
close after {unilateraltimeout} seconds if non-zero, and
the to-local output will be sent to {destination}. If
{destination} isn't specified, the default is the address
of lightningd.
Also change the pylightning:
update the `close` API to support `destination` parameter
`shutdown_scriptpubkey[REMOTE]` is original remote_shutdown_scriptpubkey;
`shutdown_scriptpubkey[LOCAL]` is the script used for "to-local" output when `close`. Add the default is generated form `final_key_idx`;
Store `shutdown_scriptpubkey[LOCAL]` into wallet;
Our policy is generally to omit fields which aren't sensible.
Also, @niftynei points out the spacing in for loops.

This triple join should be efficient to read, and to process. We have a
one-to-many (tx-to-annotations), followed by a
one-to-one (annotation-to-channel) join, so we are limited to annotations x
transactions results.
We have split the iteration over the txs and the output in different
functions, so pushing the annotation down, while keeping the transaction
addition atop. This showcases the need to not have the txid reference the
transactions.id in the DB: we annotate in a function that doesn't have the tx
index context, but only add the TX after we have finished extracting.
Currently the only source for amount_asset is the value getter on a tx output,
and we don't hand it too far around (mainly ignoring it if it isn't the
chain's main currency). Eventually we could bubble them up to the wallet, use
them to select outputs or actually support assets in the channels.
Since we don't hand them around too widely I thought it was ok for them to be
pass-by-value rather than having to allocate them and pass them around by
reference. They're just 41 bytes currently so the overhead should be ok.

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.

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
compilers assign the __LINE__ macro differently on multi-line macro
invocations.

This is dangerous but needed since postgres is not as forgiving about
unsatisfied foreign key constraints even while in a DB transaction.

We used to do some of the setup work in db.c, which is now free of any
sqlite3-specific code. In addition we also switch over to fully qualified DSNs
to specify the location of the wallet.

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.
