It's a u64, we should pass by copy. This is a big sweeping change,
but mainly mechanical (change one, compile, fix breakage, repeat).

This has the benefit of being shorter, as well as more reliable (you
will get a link error if we can't print it, not a runtime one!).

We have various functions to convert to a string, rename them all so we can
count on fmt_X being the formatter for struct X, and make them all return
`char *`.
Sometimes they existed but were private, sometimes they had a
different name. Most take a pointer, but simple types pass by copy:
short_channel_id, amount_msat and amount_sat.
The following public functions changed:
1. psbt_to_b64 -> fmt_wally_psbt.
2. pubkey_to_hexstr -> fmt_pubkey.
3. short_channel_id_to_str -> fmt_short_channel_id (scid by copy now!)
4. fmt_signature -> fmt_secp256k1_ecdsa_signature
5. fmt_amount_sat/fmt_amount_msat pass copy not pointer, return non-const char *.
6. node_id_to_hexstr -> fmt_node_id

In this case the cmd is `sql` but the field we're talking about is from
a different command, so we need a new libplugin API.
Note: there are still no deprecations in any tables used by `sql`, so this
is a bit moot for now.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
When we allow deprecation to be set per-connection, we need to
generalize this approach. Instead of filtering out deprecated
fields at schema loading, we need to load them, then refuse
to serve deprecated fields on a per-request basis.

`struct column` has a dynamically allocated member, which is neater if
it is a tal object itself (we allocated the member off the array, instead).
We're about to add two new members, so clean this up first.

I added a plugin arg and was surprised that compile didn't break.
This is because typesafe_cb et al are conditional casts: if the type
isn't as expected it has no effect, but we're passing plugin_option() through
varargs, so everything is accepted!
Add a noop inline to check type, and fix up the two cases where we
used `const char *` instead of `char *`.

We didn't handle the case of an array inside a subobject. But that
happens when we add the next commit!

Without this patch, we only ever loaded the "nodes" table once, then
didn't see updates.
How this ever got past CI is a mystery; perhaps valgrind was so slow that
the updated node_announcement hit the gossmap before we even asked sql
on l3 about the nodes table?

Changelog-Fixed: Plugins: `sql` nodes table now gets refreshed when gossip changes.
I noticed that our subtables were not being cleaned, despite being "ON
DELETE CASCADE". This is because foreign keys were not enabled, but
then I got foreign key errors: rowid cannot be a foreign key anyway!
So create a real "rowid" column. We want "ON DELETE CASCADE" for
nodes and channels (and other tables in future) where we update
partially.

In particular, we generate the schema part from the plugin itself.

Changelog-Added: Plugins: `sql` plugin command to perform server-side complex queries.
We now add tables to the strmap as we allocate them, since we don't
want to call "finish_td" when we're merely invoked for the
documentation, and don't need a database.

For now, we ignore every deprecated field, but put in the logic so
that future deprecations will work as expected.

This requires us to rename "index" fields, rename fields if we have a
sub-object, and create sub-tables if we have an array, and handle the
fact that some listX commands don't contain array X (listsendpays
contains "payments").

Rather than two arrays "columns" (for names) and "fieldtypes" (for
types), use a struct. This makes additions easier for successive
patches.
Also pull process_json_obj() out of the loop in list_done().
