Christian Decker 5912c68185 db: Add a hexval helper to decode hex values from db into fields 
This is going to be handy pretty soon. Channels are almost fully
blobs...

Christian Decker 34baf05973 wallet: Implement shachain persistence 
This needed a rather annoying hack since sqlite3 can only store
integers up to 2^63, so I just squash it down/invert it, and hope that
we never ever have more than 2^63 updates.

Christian Decker 28cc92cd15 gossip: Use bit 3 (mask 0x08) to signal initial routing sync 
After quite some back and forth we seem to finally agree on the bit
3 (mask 0x08) to signal optional initial_routing_sync.

Christian Decker fbe3a017a9 gossip: Fix crash of getroute if we don't know any channels 
This happens when we either have no channel open, or didn't announce
the channel. This patch just fails the getroute request. I'll later
add the non-broadcast announcement for local channels that should fix
this for unannounced channels.

Christian Decker 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.

Christian Decker 2c0b52fb77 bitcoin: Make chainparams const 
`cli` and `cli_args` were not `const` before since they are added to a
non-`const` array. Using `cast_const` we can keep them `const` without
unsafe cast.

Christian Decker 83c8c3fc52 opening: Use the correct chainparams to open a channel 
We were using the bitcoin genesis blockhash for all networks, which is
not correct, and would result in the open being aborted when talking

Rusty Russell 87232ec25c lightningd: new peer state CLOSINGD_COMPLETE. 
This is a transitional state, while we're waiting to see the
closing tx onchain (which is To Be Implemented).

The simplest way to do re-transmission is to re-use closingd, and just
disallow any updates.
