Rusty Russell 0cab9d1dd1 daemon_conn: helper to release daemon_conn.
We'll want this for the next change, where gossipd migrates remote peers
back to local ones.

Rusty Russell afea2520ba wireaddr: marshal empty address properly.
On unmarshal, we stop unmarshaling on a 0 (ADDR_TYPE_PADDING) type.  So
we should also stop marshaling in that case.

Rusty Russell 02411b04e4 channel: remove awaiting_revoke_and_ack flag.
We can tell this more generically because the count of revocations
received != count of commitments sent.  This is the correct condition
which allows us to restore the test we had to eliminate in
c3cb7f1c85.

The wire protocol uses this, in the assumption that we'll never see feerates

Rusty Russell 3c6eec87e3 Add DEVELOPER flag, set by default.
This is a bit messier than I'd like, but we want to clearly remove all
dev code (not just have it uncalled), so we remove fields and functions
altogether rather than stub them out.  This means we put #ifdefs in callers
in some places, but at least it's explicit.

We still run tests, but only a subset, and we run with NO_VALGRIND under
Travis to avoid increasing test times too much.

Rusty Russell 2273ce783e dev_disconnect: support multiple disconnects in the same daemon.
We currently assume the daemon gives up; gossipd won't, and we want to

This reveals a bug (returning io_close() is bad if the call is to
duplex()), and breaks a test which now continues after dropping a
packet..
