permute_tx: reintroduce permute map.
We used to have a permutation map; this reintroduces a variant which
uses the htlc pointers directly.
We need this because we have to send the htlc-tx signatures in output
order as part of the protocol: without two-stage HTLCs we only needed
to wire them up in the unilateral spend case so we simply brute-forced
the ordering.

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.

refactor: Moving gossip/routing specific state into its own struct
This used to be part of `lightningd_state` which is being split up for
the various subdaemons. The main change is the addition of the `struct
routing_state` in `routing.h` and the addition of `rstate` in `struct
lightningd_state` for backwards compatibility.

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.
