Rusty Russell bbed5e3411 Rename subdaemons, move them into top level.
We leave the *build* results in lightningd/ for ease of in-place testing though.

Rusty Russell 153c622157 lightningd: remove lightningd_state.
Some fields were redundant, some are simply moved into 'struct lightningd'.
All routines updated to hand 'struct lightningd *ld' now.

Rusty Russell 8375857116 common: absorb remaining files from daemon/
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).

Rusty Russell 85ff95e829 common: new directory for any shared objects.
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.

Rusty Russell 2ff50107ac lightningd/hsm_control: use a simple fd for HSM.
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.

Christian Decker d6656358b5 wallet: Add bip32_base to the wallet struct
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`

Rusty Russell d95adf7f33 subd: hand through fatal messages as well to callback.
This matters in one case: channeld receiving a bad message is a
permenant failure, whereas losing a connection is transient.

Christian Decker daf8866eb5 gossip: Implement the basic node_announcement
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.

Rusty Russell fc98d797d2 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.

Rusty Russell fed25cc540 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.

Rusty Russell 38bffc0f0c lightningd/subd: support multiple fds sent at once in request reply.
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.

Rusty Russell 7525ed787a lightningd/hsm: create a peer-seed for peer secrets.
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.

Rusty Russell 1800e84db7 subdaemon: callback to handle subdaemon status updates.
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.
