funding: we process the funding locked message _after_ shortChanID is known
This commit adds a new bit of synchronization to the funding manager to
ensure that we only process the funding locked message directly _after_
the short channel ID has become available within the channel. This
fixes a possible bug wherein we would receive the funding locked
message, and register the channel with the switch without yet knowing
the short chan ID. This would then cause any HTLC’s routed to the new
channel to fail, as it would be using the incorrect short channel ID.

funding: obtain and populate shortChanID for MarkChannelAsOpen
This commit modifies the funding process to use the short channel ID,
rather than only the opening block height to mark a channel as open
once it has been confirmed. With this change, the short channel ID
information will now be available immediately after the channel has
been confirmed in the chain.

routing: add ToHopPayloads method to routing.Route
This commit adds a new method to the routing.Route struct:
ToHopPayloads. This function will converts a complete route into the
series of per-hop payloads that is to be encoded within each HTLC using
an opaque Sphinx packet.

We can now use this function when creating the sphinx packet to
properly encoded the hop payload for each hop in the route.

routing: populate the OutgoingTimeLock field within route hops
This commit inches towards fully validation+adherance of the per-hop
payloads within an HTLC’s route by properly calculating the outgoing
time lock value for each hop according to the current draft
specification.

channeldb: replace opening height will short chan ID in OpenChannel
This commit modifies the OpenChannel struct to include the full short
channel ID rather than simply the opening height. This new field will
be needed by an upcoming change to uniformly switch to using short
channel ID’s when forwarding HTLC’s due to the change in per-hop
payloads.

routing/chainview: make filter updates synchronous for neutrino
This commit fixes a possible race condition wherein a call to
FilterBlock after a call to UpdateFilter would result in the call to
FilterBlock not yet using the updated filter. We fix this by ensuring
the internal chain filter is updated by the time the call to
FilterBlock returns.

lnwallet: fix race condition in channel state machine, use single mutex
This commit fixes a race condition that was discovered as a result of
the new htlcswitch package. The StateSnapshot method and all of the
other methods which mutate the state of the channel state machine were
using distinct mutexes. The fix is trivial: all methods accessing the
internal channel state variable now use the same mutex.

routing/chainview: optimize neutrino implementation of FilterBlock
This commit optimizes the neutrino implementation of FilterBlock method
of the ChainView interface. The old implementation would _always_ fetch
the entire block and manually scan through it. Instead, we can just
fetch the filter, and then if the items match, fetch the block itself.
This will save bandwidth during a lnd node’s pruning of the channel
graph after a period of dormancy.

lnwallet/btcwallet: properly pass in FeeEstimator to btcwallet
This commit fixes a bug wherein the wallet would use the default relay
fee to craft transactions. On testnet, this might be insufficient or be
rejected all together in a mainnet setting. Therefore, we now pass in
the FeeEstimator interface and ensure that it’s consulted in order to
set the relay fee the wallet will use to craft transactions.

Note that this is a hold over until we have true dynamic fee
calculation within lnd which can then be extended to the internal
wallets.

lnd: decouple rpcServer from server, wait till chain synced before starting server
This commit overhauls the way that lnd is created with the goal of
ensuring the chain backends are fully synced up before the daemon
itself starts. The rpcServer has been slightly decoupled from the
server itself s.t we can start the rpcServer independently of the
server. This is required as we’ll now wait (unless we’re in simnet
mode) for the chain to fully sync up before we even _start_ any of the
server’s goroutines.

channeldb: store the funding transaction broadcast height for channels
This commit expands the field within the OpenChannel struct in order to
start tracking the height that the funding transaction was initially
broadcast. Other sub-systems within lnd can now use this data to give a
more accurate height hint to the ChainNotifier, or to use during the
funding workflow to decide if a channel should be forgotten after it
fails to confirm for N blocks.

server: Peers method now grabs data directly with read mutex
This commit modifies the Peers method on the server such that a caller
is able to query this method without the main serger goroutines
started. This is a small component in a larger change which will let us
