connectd will be keeping the conn open, so it needs to free this
"conn_timeout" timer. Pass it through, so we can do that.

If the port is set, we spawn it (lightning_websocketd) on any
connection to that port. That means websocketd is a per-peer daemon,
but it means every other daemon uses the connection normally (it's
just actually talking to websocketd instead of the client directly).

We should actually be including this (as it may define _GNU_SOURCE
etc) before any system headers. But where we include <assert.h> we
often didn't, because check-includes would complain that the headers
included it too.
Weaken that check, and include config.h in C files before assert.h.

common/onion is going to need to use this for the case where it finds a blinding
seed inside the TLV. But how it does ecdh is daemon-specific.
We already had this problem for devtools/gossipwith, which supplied a
special hsm_do_ecdh(). This just makes it more general.
So we create a generic ecdh() interface, with a specific implementation
which subdaemons and lightningd can use.

This will help with the next patch, where we wean off using a global
for features: connectd.c has access to the feature bits.
Since connectd might now want to send a message, it needs the crypto_state
non-const, which makes this less trivial than it would otherwise be.

This fixes block parsing on testnet; specifically, non-standard tx versions.
We hit a type bug in libwally (wallt_get_secp_context()) which I had to
work around for the moment, and the updated libsecp adds an optional hash
function arg to the ECDH function.
Fixes: #2563

It's more natural than using a zero-secret when something goes wrong.
Also note that the HSM will actually kill the connection if the ECDH
fails, which is fortunately statistically unlikely.
