Note that other directories were explicitly depending on the generated

$(LIGHTNINGD_HSM_CLIENT_OBJS), so we remove that.

Since we now over-write the wally malloc/free functions, we need to do
so for tests as well. Here we pull up all of the common setup/teardown

Adds a new plugin notification for getting information about coin

called from within lightningd. Separated from the 'common' set because
the lightningd struct is required to finalize the blockheight etc

3b4a06f52b common: generalize ecdh function.
common/onion is going to need to use this for the case where it finds a blinding
seed inside the TLV.  But how it does ecdh is daemon-specific.

We already had this problem for devtools/gossipwith, which supplied a
special hsm_do_ecdh().  This just makes it more general.

So we create a generic ecdh() interface, with a specific implementation
which subdaemons and lightningd can use.

f7ebbb2ec5 common: make sphinx code ignorant of payload format.
Now "raw_payload" is always the complete string (including realm or length
bytes at the front).

This has several effects:
1. We can receive an decrypt an onion which is grossly malformed.
2. We can still hand this to the htlc_accepted hook.
3. We then fail it unless the htlc_accepted accepts it manually.
4. The createonion API now takes the raw payload, and does not know
   anything about "style".

The only caveat is that the sphinx code needs to know the payload
length: we have a call for that, which simply tells it to copy the
entire onion (and treat us as the final node) if it's invalid.

220449e1cd ccan: import ccan/json_out and ccan/json_escape.
These are generalized from our internal implementations.

The main difference is that 'struct json_escaped' is now 'struct
json_escape', so we replace that immediately.

The difference between lightningd's json-writing ringbuffer and the
more generic ccan/json_out is that the latter has a better API and
handles escaping transparently if something slips through (though
it does offer direct accessors so you can mess things up yourself!).

b4455d517c common/node_id: new type.
Node ids are pubkeys, but we only use them as pubkeys for routing and checking
gossip messages.  So we're packing and unpacking them constantly, and wasting
some space and time.

This introduces a new type, explicitly the SEC1 compressed encoding
(33 bytes).  We ensure its validity when we load from the db, or get it
from JSON.  We still use 'struct pubkey' for peer messages, which checks
validity.

f8f76e3d31 plugin: Add hook registration
I might have gone a bit overboard with the type-checking, but
typesafe_cb_cast is quite nice to use, so why not. The macro to
register a new hook encapsulates the entire flow from param
serialization, to dispatch, parsing and callback dispatch in one
bundle. I was tempted to have the callback outside of the
registration, but it's unlikely that we'll have two calls to the same
hook with different callbacks.

e17f69ce2d json_stream: disentangle JSON handling from command.
We promote 'struct json_stream' to contain the membuf; we only attach
the json_stream to the command when we actually call
json_stream_success / json_stream_fail.

This means we are closer to 'struct json_stream' being an independent
layer; the tests are already modified to use it directly to create
JSON.

This is also the first step toward re-enabling non-serial command
execution.

3d3d2ef9af gossipd: remove connectd functionality, enable connectd.
This patch guts gossipd of all peer-related functionality, and hands
all the peer-related requests to channeld instead.

gossipd now gets the final announcable addresses in its init msg, since
it doesn't handle socket binding any more.

lightningd now actually starts connectd, and activates it.  The init
messages for both gossipd and connectd still contain redundant fields
which need cleaning up.

There are shims to handle the fact that connectd's wire messages are
still (mostly) gossipd messages.
