hsm: new fd type for channeld.
Instead of reusing HSMFD_ECDH, we have an explicit channeld hsm fd,
which can do ECDH and will soon do channel announce signatures as well.

We *should* split the struct into key and data, rather than only comparing

This lets us link HTLCs from one peer to another; but for the moment it

Update wire from spec ed107e4ef019f33a88aa5567adca7fbb944e93af
This version correctly extracts fields with _ in them, meaning we get
more fields.
Also adds Makefile dependency which I noticed broke the build.

lightningd/subd: add a context to requests.
If a peer dies, and then we get a reply, that can cause access after free.
The usual way to handle this is to make the request a child of the peer,
but in fact we still want to catch (and disard) it, so it's a little
more complex internally.

We can usefully have them tell is if there is outstanding work to do,
too.

The three cases we care about only happen on specific transitions:
1. They can no longer spend our failed HTLC: we can fail the source now.
2. They are fully committed to their new HTLC htlc: we can forward now.
3. They can no longer timeout their fulfilled HTLC: the funds are ours.
