We temporarily hack to sync_crypto_write/sync_crypto_read functions to
not do any crypto, and do it all in connectd.

Once connectd is doing this, we can't close as soon as we send,
and in fact we can't do 'fail write' either.

And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).
config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

After recent header files clean-up it was not possible to
build c-lightning 7401b2682. This patch fixes it both for
Alpine Linux and OpenBSD.

This allows us to ensure a packet is read by the other end, but we
don't read anything else from them or write anything to them.
Using '+' is similar, but because it closes the connection, the peer
might notice before receiving the packet (such as if it does a write).

This is ignored in subdaemons which are per-peer, but very useful for
multi-peer daemons like connectd and gossipd.

And clean up some dev ones which actually happen (mainly by calling
channel_fail_permanent which logs UNUSUAL, rather than
channel_internal_error which logs BROKEN).

Encapsulating the peer state was a win for lightningd; not surprisingly,
it's even more of a win for the other daemons, especially as we want
to add a little gossip information.

Avoid that 200ms loss. We don't want to disable nagle generally,
since it's great for gossip and other traffic; we just want to push at
critical times.

tal_count() is used where there's a type, even if it's char or u8, and
tal_bytelen() is going to replace tal_len() for clarity: it's only needed
where a pointer is void.
We shim tal_bytelen() for now.

Currently it's always for messages to peer: make that status_peer_io and
add a new status_io for other IO.

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.

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.
