I have seen some strange flakiness (under VALGRIND), which I have
traced down to dev-disconnect "+" not working as expected. In
particular, the message is not sent out before closing the fd.
This seems to fix it on Linux, though it's so intermittant that it's hard
to be completely sure.

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.

We currently assume the daemon gives up; gossipd won't, and we want to
test it there too.
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..

Useful if we want to drop & suppress, for example. We change '=' to mean
do nothing to the packet.
We use this to clean up the test_reconnect_sender_add test.

To reproduce the next bug, I had to ensure that one node keeps thinking it's
disconnected, then the other node reconnects, then the first node realizes
it's disconnected.
This code does that, adding a '0' dev-disconnect modifier. That means
we fork off a process which (due to pipebuf) will accept a little
data, but when the dev_disconnect file is truncated (a hacky, but
effective, signalling mechanism) will exit, as if the socket finally
realized it's not connected any more.
The python tests hang waiting for the daemon to terminate if you leave
the blackhole around; to give a clue as to what's happening in this
case I moved the log dump to before killing the daemon.

We use a file descriptor, so when we consume an entry, we move past it
(and everyone shares a file offset, so this works).
The file contains packet names prefixed by - (treat fd as closed when
we try to write this packet), + (write the packet then ensure the file
descriptor fails), or @ ("lose" the packet then ensure the file
descriptor fails).
The sync and async peer-write functions hook this in automatically.
