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 remove the unused status_send_fd, and rename status_send_sync (it
should only be used for that case now).
We add a status_setup_async(), and wire things internally to use that
if it's set up: status_setup() is renamed status_setup_sync().

Since we use async IO, we can't use status_send. We keep a pointer to the
master daemon_conn, and use that to send.

We use the fourth value (size) to determine the type, unless the fifth
value is suppled. That's silly: allow the fourth value to be a typename,
since that's the only reason we care about the size at all!
Unfortunately there are places in the spec where we use a raw fieldname
without '*1' for a length, so we have to distingish this from the
typename case.

This is a bit tricky: for our signing code, we don't want scriptsigs,
but to calculate the txid, we need them. For most transactions in lightning,
they're pure segwit so it doesn't matter, but funding transactions can
have P2SH-wrapped P2WPKH inputs.

I made it privkey to prove we owned one key, but without the HSM checking
we have a valid sig for the first commitment transaction, and that
we haven't revealed the revocation secret key, why bother?

For the moment this is simply handed through to lightningd for
generating the per-peer secrets; eventually the HSM should keep it and
all peer secret key operations would be done via HSM-ops.

The problem with wire headers not being generated in time before stuff
depended on it turns out to be related with inclusion order of
sub-makefiles. The inclusions must preceed the use of
LIGHTNINGD_HEADERS since they append to that variable.
