3404509928 wallet: Move UTXO tracking to DB
Since we have a simple way to query the database for UTXOs we can
simplify some of the coin selection logic. That gets rid of the
in-memory list of UTXOs.

7e0b9bd1ab wallet: Always use the DB backed bip32_max_index
We were loading it on startup and updating as we went. Removing
caching to reduce chances of becoming desynchronized.

257ecf6222 wallet: Helper to store/retrieve persistent vars to/from DB
Not the nicest code, but it allows us to store the bip32_max_index so
that we don't forget our addresses upon restart. We could have done
the same by retrieving the max index from our index, but then we'd
forget addresses that don't have an associated output. Conversion
to/from string is so that we can store arbitrary one off values in the
DB in the future, independent of type.

9882a9fb29 wallet: Start the wallet interface and link it into lightningd
The database is hidden behind the wallet interface, which has all the
wallet specific functionality. First up is the tracking of outputs.

9b1d240c1f lightningd: --dev-disconnect support.
We use a file descriptor, so when we consume an entry, we move past it
(and everyone shares a file offset, so this works).

The file contains packet names prefixed by - (treat fd as closed when
we try to write this packet), + (write the packet then ensure the file
descriptor fails), or @ ("lose" the packet then ensure the file
descriptor fails).

The sync and async peer-write functions hook this in automatically.

b4beab6537 gossip: Make the broadcast interval configurable
Adds a new command line flag `--dev-broadcast-interval=<ms>` that
allows us to specify how often the staggered broadcast should
trigger. The value is passed down to `gossipd` via an init message.

This is mainly useful for integration tests, since we do not want to
wait forever for gossip to propagate.

826fb0c2dc lightningd: track HTLC ends.
This lets us link HTLCs from one peer to another; but for the moment it
simply means we can adjust balance when an HTLC is fulfilled.

95f41287f0 lightningd/subd: new code for subdaemons.
This uses a single fd for both status and control.

To make this work, we enforce the convention that replies are the same
as requests + 100, and that their name ends in "_REPLY".

This also means that various daemons can simply exit when done; there's
no race between reading request and closing status fds.

2ce6a4bcca daemon/peer: move struct peer to internal header.
We use a different 'struct peer' in the new daemons, so make sure
the structure isn't assumed in any shared files.

This is a temporary shim.

3cb576d69d refactor: Moving gossip/routing specific state into its own struct
This used to be part of `lightningd_state` which is being split up for
the various subdaemons. The main change is the addition of the `struct
routing_state` in `routing.h` and the addition of `rstate` in `struct
lightningd_state` for backwards compatibility.
