Rusty Russell 00a0d09340 tools/check-includes.sh: test that c files include their .h files.
This is best-practice (to ensure prototypes match up), but there were a
few places we didn't (at least, directly).  Make it a requirement,
either of form "foo.h" or <dir/foo.h>.

The noise is the change to our print templates.

Rusty Russell cb22015b2a common/channel_type: wrapper for generated 'struct channel_type'.
We make it a first-class citizen internally, even though we won't use
it over the wire (at least, non-experimental builds).  This scheme
follows the latest draft, in which features are flagged compulsory.

We also add several helper functions.

Since uses the *even* bits (as per latest spec), not the *odd* bits,
we have some other fixups.

This includes the new bolt11 test vectors, and also removes the

niftynei 0f05238e97 psbt: set the witness script to null, also
Otherwise libwally pushes the psbt-key for 'witness script' onto the
serialized version and we fail the 'is this identical' check.

Relevant line from libwally, where if bytes, we push a psbt_key.

```
static void push_typed_varbuff(unsigned char **cursor, size_t *max,
                               uint64_t type,
                               const unsigned char *bytes, size_t bytes_len)

    if (bytes) {
        push_psbt_key(cursor, max, type, NULL, 0);
        push_varbuff(cursor, max, bytes, bytes_len);
    }

Rusty Russell 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.

Rusty Russell c448170d5f common/bolt12_merkle.c: fix comments.
I spent an hour thinking this code had a bug (see test vector fix);
we *do* overallocate the tree, but that's deliberate: we fill with NULLs
and ignore on recursion.

The Merkle recurse comment had an out-by-one, and the NULL-pad
technique used was uncommented.
