Change all calls to use the correct serialization and deserialization
functions, include the correct headers and remove the control
messages.

Some fields were redundant, some are simply moved into 'struct lightningd'.
All routines updated to hand 'struct lightningd *ld' now.

Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':', not '/' too).

To avoid everything pulling in HTLCs stuff to the opening daemon, we
split the channel and commit_tx routines into initial_channel and
initial_commit_tx (no HTLC support) and move full HTLC supporting versions
into channeld.

Now we're always sync, just use an fd. Put the hsm_sync_read() helper
here, too, and do HSM init sync which makes things much simpler.

Wallet should really be the container for anything bip32 related, so
I'd like to slowly wean off of `ld->bip32_base` in favor of
`ld->wallet->bip32_base`
This matters in one case: channeld receiving a bad message is a
permenant failure, whereas losing a connection is transient.

Rather a big commit, but I couldn't figure out how to split it
nicely. It introduces a new message from the channel to the master
signaling that the channel has been announced, so that the master can
take care of announcing the node itself. A provisorial announcement is
created and passed to the HSM, which signs it and passes it back to
the master. Finally the master injects it into gossipd which will take
care of broadcasting it.
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.

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.

Instead of indicating where to place the fd, you say how many: the
fd array gets passed into the callback.
This is also clearer for the users.

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.

It's a bit messy, since some status messages are accompanied by an FD:
in this case, the handler returns STATUS_NEED_FD and we read that then
re-call the handler.
