Rusty Russell c328a76438 channeld: use flags to track whether changes are pending.
This is required when we have non-HTLC changes (ie. fees).

This means we'll find anywhere still using the payment key,
even though we still expose the private payment key to channeld.

Rusty Russell 5502a19d1e json: reject incoming JSON which has any unusual characters in tokens.
ie. non-printable, quotes or escapes.  We allow these outside tokens
(we expect tabs and \n for example).

This is a big hammer, but if someone really wants we can add support
later.

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

duplex()), and breaks a test which now continues after dropping a

Rusty Russell ef28b6112c status: use common status codes for all the failures.
This change is really to allow us to have a --dev-fail-on-subdaemon-fail option
so we can handle failures from subdaemons generically.

It also neatens handling so we can have an explicit callback for "peer
did something wrong" (which matters if we want to close the channel in
that case).

Rusty Russell 5889ad5fc4 dev-disconnect: add blackhole option.
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.
