A convenient alias for char *, though we don't allow control characters
so our logs can't be fooled with embedded \n.

We used to use a hack for gossip_resolve_channel_reply, where we'd send
a NULL key on failure. It's now been neatened to use a counter, so we
don't need this.

Removes the need to keep a second transaction around and marking it as
`noleak`, just to make sure that dependencies are not free'd along
with the original tx.

memcmp((p1)->field, (p2)->field, ...) results in undefined behaviour
if (p1)->field or (p2)->field is NULL. This holds also when
tal_count((p1)->field) * sizeof(*(p1)->field) == 0.
It's just a sha256_double, but importantly when we convert it to a
string (in type_to_string, which is used in logging) we use
bitcoin_blkid_to_hex() so it's reversed as people expect.

If send_htlc_out() fails, it doesn't initialize pc->out; that can
make us think it's still in progress.

We revert to a simple select() loop. This makes things simpler, and fixes
the problem where we want to exit but we've partially read a peer packet.
We still queue up outgoing peer packets for non-blocking send: if we
went full sync there, we'd risk deadlock if both sides wrote a huge
number of packets and neither was reading.
This also greatly simplifies the next patches, where we want to make
our first get/response from gossipd.

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.

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.
