Rusty Russell e012e94ab2 hsmd: rename hsm_client_wire_csv to hsm_wire.csv
That matches the other CSV names (HSM was the first, so it was written
before the pattern emerged).

Rusty Russell 6b6b7eac61 hsmd: use status_conn to send bad_request messages, make handlers uniform.
The current code sends hsmstatus_client_bad_request via the req fd;
this won't work, since lightningd uses that synchronously and only
expects a reply to its commands.  So send it via status_conn.

We also enhance hsmstatus_client_bad_request to include details, and
create convenience functions for it.  Our previous handling was ad-hoc;
we sometimes just closed on the client without telling lightningd,
and sometimes we didn't tell lightningd *which* client was broken.

Also make every handler the exact same prototype, so they now use the
exact same patterns (hsmd *only* handles requests, makes replies).

I tested this manually by corrupting a request to hsmd.

Rusty Russell 1e4e476c9e hsmd: implement bitcoin_key() to subsume bitcoin_pubkey and bitcoin_keypair.
This mirrors the node_key() interface we already have.

Rusty Russell 0d46a3d6b0 Put the 'd' back in the daemons.
@renepickhardt: why is it actually lightningd.c with a d but hsm.c without d ?

And delete unused gossipd/gossip.h.
