1a94e7282b db: Make peers unique by node_id
We should only ever have a single entry for each node_id, enforcing
this on the DB.

4bc0750882 wallet: Moving wallet_channel->peer_id into the peer struct
This was supposed to be a temporary solution anyway, and I had a
rather annoying mixup between peer_id and unique_id, the latter of
which is actually a connection identifier.

3fefd5f46d master: Only persist the peer/channel if we have reached openingd
There is no point in doing so before, and it'd be creating empty
entries for each connection.

e9b69b195a wallet: Store channel to db whenever something changes
This is as coarse grained as it can get, and therefore slow, but it'll
store the channel (sans HTLCs) to database so we can recover them upon
restart.

406d52042b peer: Add channel to peer and save upon opening a channel
Add the channel to the peer on the two open paths (fundee and funder)
and store it into the database. Currently fails when opening a channel
to a known peer after loading from DB because we attempt to insert a
new peer with the same node_id. Will fix later.

893335244d openingd: supply initial tx as well as signature.
And store in peer->last_tx/peer->last_sig like all other places,
that way we broadcast it if we need to.

Note: the removal of tmpctx in funder_channel() is needed because we
use txs[0], which was allocated off tmpctx.

6dbd99ddc6 gossip: Fix a race condition between release_peer and fail_peer
There was a race condition that would cause an assertion to segfault
if a call to release_peer was interleaved with a fail_peer. The
release_peer was making the peer non-local, which was then causing the
assertion in fail_peer to fail. Now we just have 3 cases: not found,
local, and non-local.

2bf92c9063 peer: Check localfeatures and globalfeatures against what we support (#195)
We support a number of features already, so failing connections
whenever we see an even bit set is not a good idea. This turned out to
kill our connections to eclair.

Also, the spec says that the LSB / bit 0 is to be counted as index 0, and
therefore even. So we need to check the lower of each 2-bit-tuple not
the higher one.
