If another channel has set the optional `htlc_maximum_msat` field,
we should correctly parse that field and respect it when drawing up
routes for payments.
BOLT 7's been updated to split the flags field in `channel_update`
into two: `channel_flags` and `message_flags`. This changeset does the
minimal necessary to get to building with the new flags.
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.

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.

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.
The spec 4af8e1841151f0c6e8151979d6c89d11839b2f65 uses a 32-byte 'channel-id'
field, not to be confused with the 8-byte short ID used by gossip. Rename
appropriately, and update to the new handshake protocol.

In particular, 860990fa0afb55f839e882a5e9abe8abe6ccb981 reordered
channel_announcement and c93bf5cf8c48eab1b028e85214cb35feeeffcbb3
reordered the update_fail_malformed_htlc message.

This is from my fix-peer-numbering branch (without that, the code
won't compile due to dup numbers) and temporarily removes the
alignment check (fails due to sha256 in update_fail_malformed_htlc,
which will be fixed in my onion-failmsg-cleanup branch.
