Use TCP pull mode (#422)

We now use [akka tcp pull mode](https://doc.akka.io/docs/akka/2.5.3/scala/io-tcp.html#read-back-pressure-with-pull-mode) for both incoming and outgoing connections.

In combination with setting a relatively low value for `akka.io.tcp.max-received-message-size`, this results in less RAM consumption, in particular when validating a whole routing table.

Also improved the router:
- Removed the grouping of `channel_announcement` because batching is done lower in the stack, in the bitcoin json-rpc client. Channels are now validated as they arrive.
- Keep track of all origin peers for every announcement (instead of the first one), in order not to send back the same announcements to peers.
- Better choice of data structures, which increases constant time operation (but don't completely eliminate less efficient access)
- Reworked management of private/not-yet-announced channels
