I've changed the way libbitcoin connects to a more saner policy. There
are now a fixed number of slots and it always tries to maintain a
constant amount of connections. Before it was aggressively chasing
connections which was poorly thought out.

It might be more unstable because there are more asserts, but they will
help catch out any deeper bugs in the network code.
