27e0ea2358 wire: remove special zero-key handling.
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.

248879e203 wire: Move bitcoin_tx serialization from htlc_wire to wire
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.

7b80e5b66c Avoid undefined behaviour in eq_var(p1, p2, field)
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.

810abb6b21 bitcoin: create new wrapper type bitcoin_blkid, log backward endianness.
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.

477a529856 pay: make sure we don't think payment in progress if it immediately fails.
If send_htlc_out() fails, it doesn't initialize pc->out; that can
make us think it's still in progress.

9de3827199 channeld: don't use ccan/io, go sync.
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.

40315bfb91 test: fix dependencies.
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.

7e022b522c gossipd: don't try to handle padding inside fromwire_ipaddr.
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.
