8c468c1e15 daemon: use fee rates rather than absolute fees (BOLT #2) 
And divide fees as specified there.

We still use fixed values rather than floating, and we don't send or
handle update_fee messages.

b423b33236 protocol: implement close as per BOLT #2. 
We don't actually implement closing when we have HTLCs (we should
allow it, as that's what the clearing phase is for), since soon we'll
rewrite HTLC to match the async HTLC protocol of BOLT #2.

Note that this folds the close paths, using a simple check if we have
a close transaction.  That's a slight state layer violation, but
reduces code duplication.

45c5c83d6f daemon: exit main loop to free dead peers. 
When a peer is finally to be freed (ie. STATE_CLOSED), doing this
inside the state logic is a bit fraught.  We're better off exiting the
io loop and freeing it there.

5b9f8d8bbd bitcoind: serialize requests. 
bitcoind has a limit of 16 requests at once, by default, so our simplest
solution is to serialize them.

34e32978b8 bitcoind: warn if their bitcoin config doesn't have walletbroadcast=0. 
Because we use the bitcoin wallet to create the anchor transaction, we
need to make sure it doesn't broadcast it; safest to check their config
for the option.
