This seems to be a cut & paste bug (mine, AFAICT!) from the command code:
```
rune = rune_derive_start(cmd, master_rune,
tal_fmt(tmpctx, "%"PRIu64,
rune_counter ? *rune_counter : 0));
```
In that case, rune_counter was a pointer, which could be NULL.

It always is for runes we create, but in theory you can take our secret key
and make our own runes with your own tools.
(We correctly refuse runes without uniqueids if they're *not* ours
anyway: uniqueid is only used for our own runes).

nodeid is only useful when we know the peer we're talking to (e.g. commando).

No-schema-diff-check: We're simply making optional, not deprecating!
Indeed, we can fall through this if it's not a valid enum value.

We want to access this in db migrations, which happen very early, but
runes_init needs the db, creating a circular dependency which must be
split.

The uid isn't enough: it could be someone else's rune. This is tested
in the command rune list tests.

This extracts the core checking functionality for a rune, so they can
easily be used more widely than just commando.
