Test objects must be added to $(ALL_OBJS) so they correctly depend on
CCAN headers etc.
Also, each test in a subdir must depend on headers and src in the parent
directory, as it will often #include them directly.

In future it will have TOR support, so the name will be awkward.
We collect the to/fromwire functions in common/wireaddr.c, and the
parsing functions in lightningd/netaddress.c.

It makes it impossible to embed an ipaddr in another structure, since we
always try to skip over any zeroes, which may swallow a following field.
Do the skip specially for the case where we're parsing routing messages:
we never use padding for our own internal messages anyway.

GCC optimizes it out anyway: I sent an uninitialized var and it sent 8!
The receiver checks the value is 0 or 1 anyway.

1. The code to skip over padding didn't take into account max.
2. It also didn't use symbolic names.
3. We are not supposed to fail on unknown addresses, just stop parsing.
4. We don't use the read_ip/write_ip code, so get rid of it.

Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':', not '/' too).

To avoid everything pulling in HTLCs stuff to the opening daemon, we
split the channel and commit_tx routines into initial_channel and
initial_commit_tx (no HTLC support) and move full HTLC supporting versions
into channeld.

After quite some back and forth we seem to finally agree on the bit

The next patch includes wire/peer_wire.h and causes a compile error
as lightningd/gossip_control.c defined its own gossip_msg function.
New names are clearer.

Fixes the `short_channel_id` being serialized as 4 bytes block height,
3 bytes transaction index and 1 byte output number, to use 3+3+2 as
the spec says.
The reordering in the unit test structs is mainly to be able to still
use `eq_upto` for tests.
I caught the gossip daemon freeing a message, while it was queued to be
written. Using tal_dup_arr() is the Right Thing, as it handles taken()
properly automatically.

wire_io: make a copy in io_write_wire (unless taken()).
I hit a corner case where gossipd freed a duplicate while it was being
sent out; this kind of thing doesn't happen if io_write_wire() makes
a copy by default.
We also do a memcheck() here; this gives us a caller in the backtrace
if there are uninitialized bytes, rather than waiting until the write
which happens later.

Now in sync with 8ee57b97738b1e9467a1342ca8373d40f0c4aca5.
Our tool doesn't need to convert them any more, but we actually had a
mis-typed field in the HSM which needed fixing.

We alternated between using a sha256 and using a privkey, but there are
numerous places where we have a random 32 bytes which are neither.
This fixes many of them (plus, struct privkey is now defined in terms of
struct secret).

We were getting an assert "!secp256k1_fe_is_zero(&ge->x)", because
an all-zero pubkey is invalid. We allow marshal/unmarshal of NULL for
now, and clean up the error handling.
1. Use status_failed if master sends a bad message.
2. Similarly, kill the gossip daemon if it gives a bad reply.
3. Use an array for returned pubkeys: 0 or 2.
4. Use type_to_string(trc, struct short_channel_id, &scid) for tracing.

Mainly switching from the old include to the new include and adjusting
the actual size of the onion packet. It also moves `channel.c` to use
`struct hop_data`.
It introduces a dummy next hop in `channel.c` that will be replaced in
the next commit.
