3b622f06c3 lightningd: use param_check on all commands which do extra checks.
This makes `check` much more thorough, and useful.

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: JSON-RPC: `check` now does much more checking on every command (not just basic parameter types).

aab948e538 datastore: Add datastoreusage command
datastoreusage returns the total_bytes that are stored under a given
{Key} or from root. {Key} is the entry point from which we begin to
traverse the datastore.

Changelog-Added: JSON-RPC: `datastoreusage`: returns the total bytes that are stored under a given key.

e39c80bf8b lightningd: simplify datastore internal db API.
The wallet_datastore_first() SELECT statement only iterates from the
given key (if any), relying on the caller to notice when the key no
longer applies.  (e.g. startkey = ["foo", "bar"] will return key
["foo", "bar"] then ["foo", "bar", "child" ], then ["foo", "baz"]).

The only caller (listdatastore) would notice the keychange and stop
looping, but reallly wallet_datastore_next() should do this.  When I
tried to use it for migrations, I got very confused!

Also, several places want a simple "wallet_datastore_get()" function,
so provide that.

9a77a995a8 lightningd: unescape JSON strings for db.
We were feeding in the raw JSON, which escapes \".  Then we were
escaping *again* to return it.

80250f9b60 datastore: Add check for empty key array
We need to check if the key parameter is an empty array in
`listdatastore` as we do assume an array of at least length 1 in
`wallet.c:5306`.

401f1debc5 common: clean up json routine locations.
We have them split over common/param.c, common/json.c,
common/json_helpers.c, common/json_tok.c and common/json_stream.c.

Change that to:
* common/json_parse (all the json_to_xxx routines)
* common/json_parse_simple (simplest the json parsing routines, for cli too)
* common/json_stream (all the json_add_xxx routines)
* common/json_param (all the param and param_xxx routines)

4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).

config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

fe86c117d9 datastore: turn keys into arrays
After some discussion with @shesek, and my own usage, we agreed that
a more comprehensive interface, which explicitly supports grouping,
is desirable.

Thus keys are now arrays, with the semantic that a key is either a
parent or has a value, never both.

For convenience in the JSON schema, we always return them as arrays,
though we accept simple strings as arguments.

533571a655 datastore: add generation, simple atomicity.
We add a generation counter, and allow update or del conditional
on a given generation.

Formalizes error codes, too, since we have more now.
