4bf398c4e7 status: move into lightningd/status.
It's really a lightningd-only thing, and we're about to do surgery on it.

74df755a29 gossip: Added nested message types for getnodes query
Added a struct that represents a single entry in a `getnodes` reply,
so that we can append one after the other and parse them again on the
other side.

95f41287f0 lightningd/subd: new code for subdaemons.
This uses a single fd for both status and control.

To make this work, we enforce the convention that replies are the same
as requests + 100, and that their name ends in "_REPLY".

This also means that various daemons can simply exit when done; there's
no race between reading request and closing status fds.

c64447a929 lightningd/derive_basepoints: hoist derivation logic.
All the daemons will use a common seed for point derivation, so drag
it out of lightningd/opening.

This also provide a nice struct wrapper to reduce argument count.

edc30b12ea lightningd: --dev-debugger=<subdaemon>
Or for blackbox tests --gdb1=<subdaemon> / --gdb2=<subdaemon>.

This makes the subdaemon wait as soon as it's execed, so we can attach

76e2c980e1 gossip: Moving to intmap-based broadcast for the legacy daemon
Moved the broadcast functionality to broadcast.[ch]. So far this
includes only the enqueuing side of broadcasts, the dequeuing and
actual push to the peer is daemon dependent. This also adds the
broadcast_state to the routing_state and the last broadcast index to
the peer for the legacy daemon.

b41d71da30 Makefile: Making sure header vars are populated correctly
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.
