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.

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.

We were using the bitcoin genesis blockhash for all networks, which is

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.

9ec804341c channeld: fix intermittant failure on reading init msg from master. 
As tracked down by Christian; by setting up the master conn first,
we make the master fd async.  This means that the synchronous read
(in init_channel) can fail with -EAGAIN, and indeed, Christian
saw this when not running under valgrind.

c05f63a4db peer_control: fix double-state transition on reconnect. 
We actually don't need to transition if we're reconnecting, and logic
to go to CHANNELD_NORMAL was wrong: we checked that we'd seen funding tx
locked, but not that we'd received a msg from the remote peer.

We need to fix the tests now we no longer double-transition, too.
