lnd: add new "perm" bit to the ConnectPeer RPC call
This commit modifies the ConnectPeer RPC call and partitions the
behavior of the call into two scenarios: the connection should be
persistent which causes the call to be non-blocking, and the connection
should only attempt to connect once — which causes the call to be
blocking and report any error back to the caller.

As a result, the pendingConnRequest map and the logic around it is no
longer needed.

lnd: add support for pushing funds as part of channel funding
This commit adds daemon level support for pushing funds as part of the
single funder channel workflow. This new feature allows the user to
open a channel and simultaneously make a channel at the same time which
can improve the UX when setting up a channel for the first time.

multi: update btcsuite API's to latest upstream changes
This commit makes a large number of minor changes concerning API usage
within the deamon to match the latest version on the upstream btcsuite
libraries.

The major changes are the switch from wire.ShaHash to chainhash.Hash,
and that wire.NewMsgTx() now takes a paramter indicating the version of
the transaction to be created.

multi: allow force channel closures while not connected to peer
This commit adds a much needed feature to the daemon, namely the
ability to force close a channel while the source daemon doesn’t have
an active connection to the counter party. Previously this wasn’t
possible as ALL channel closures were routed through the htlcSwitch
which is only able to trigger a channel closure if the peer is online.

To remedy this, if the closure type is “force” then, we now handle the
channel closure and related RPC streaming updates from the call handler
site of the RPC itself. As a result, there are now only two htlcSwitch
channel closure types: breach, and regular. The logic that’s now in the
rpcSever should likely be refactored into a distinct sub-system, but
getting the initial functionality in is important.

Finally, the channel breach integration test has been modified to skip
connection the peers before attempting the forceful channel closure of
a revoked state as the remote peer no longer needs to be online.

rpcserver: return an encoded payment request in AddInvoice
This commit modifies the generated response to an “AddInvoice” RPC by
including an encoded payment request in the response. This change gives
callers a new atomic piece of information that they can present to the
payee, to allow completion of the payment in a seamless manner.

breacharbiter: introduce new sub-system to watch for breaches
This commit introduces a new sub-system into the daemon whose job it is
to vigilantly watch for any potential channel breaches throughout the
up-time of the daemon. The logic which was moved from the utxoNursery
in a prior commit now resides within the breachArbiter.

Upon start-up the breachArbiter will query the database for all active
channels, launching a goroutine for each channel in order to be able to
take action if a channel breach is detected. The breachArbiter is also
responsible for notifying the htlcSwitch about channel breaches in
order to black-list the breached linked during any multi-hop forwarding
decisions.

rpcserver: fetch balance for ChannelBalance from disk
This commit modifies the ChannelBalance RPC to fetch the balance from
disk since channels are now able to efficiently retrieved from disk due
to recent index that have been added. Previously this RPC would only

routing: update Sphinx API to include r-hash and per-hop-payload
This commit modifies both the Sphinx packet generation and processing
for recent updates to the API.

With the version 1 Sphinx specification, the payment hash is now
included in the MACs in order to thwart any potential replay attacks.
As a result, any attempts to replay previous HTLC packets MUST re-use
the same payment hash, meaning that the first-hop node can simply
settle the HTLC immediately, thwarting the attacker.

Additionally, within the Sphinx packet, each hop now gets a per-hop
payload which contains the necessary details (CTLV value, fee, etc) for
the node to successfully forward the payment. This per-hop payload is
protected by a packet-wide MAC.

rpc: query the database instead of active peers for the ListChannel RPC
This commit takes advantage of the newly added
channeldb.FetchAllChannels method to return the state of all active
channels for the ListChannels RPC command. With this change the state
of all channels can now be queried regardless of if any/all the peers
are currently online.

In a future modification a bit will be added to the channel information
which indicates if the LinkNode the channel was created with is
currently online or not.

rpc: create new goroutine to read new payments for SendPayment
This commit modifies the server-side handling of the streaming
SendPayment RPC to launch a new goroutine which is dedicated to reading
new requests from the client from the bi-directional stream. This
modification decouples error handling from stream reading allowing
errors to be returned to the client as the arise rather than after the
next payment has been sent.

rpcserver: use the first hop pubkey as the dest to the htlcSwitch
This commit modifies the sendpayment command slightly to use the pub
key of the *first* hop within the route as the destination within the
htlcPacket sent to the htlcSwitch.

Previously, since only single hop was implemented, the final
destination would be set within the htlcPkt, causing the route to fail
as the switch doesn’t have a direct link to the dest in the multi-hop
case.

lnd: integrate Sphinx onion routing when sending/receiving HTLC's
This commit alters the send/receive HTLC pipe line a bit in order to
fully integrate onion routing into the daemon.

The server now stores the global Sphinx router which all active
htlcManagers will used when processing upstream HTLC add messages.
Currently the onion routing private key is static, and identical to the
node’s current identity public key. In the future this key will be
rotated daily the node based on the current block hash.

When sending a payment via the SendPayment RPC, the routing manager is
now queried for the existence of a route before the payment request is
sent to the HTLC switch. If a path is found, then a Sphinx onion packet
encoding the route is created, then populated within the HTLC add
message.

Finally, when processing an upstream HTLC add request, the sphinx
packet is decoded, then processed by the target peer. If the peer is
indicated as the exit node, then the HTLC is queue’d to be settled
within the next state update.

config: add a new --debughtlc config parameter
This commit adds a new configuration parameter to the deamon:
‘DebugHTLC’. When true, all outgoing HTLC’s sent via the RPC interface
will be sent paying to a special rHash value which all lnd nodes also
with the flag activated know the preimage to. Therefore all payments
sent to a 1-hop node will immediately be settled by that node.

By default, this flag is false, it it only intended to be used to
exercise local changes to 1-hop behavior manually.

2788dbeaa8 Add RPC to show current total available channel capacity #29 (#35)
This commit adds a new RPC command: `channelbalance` which returns the
sum of all available channel capacity across all open channels. The
total balance is currently returned in units of `satoshis`. Additionally
the `networkHarness` has been modified slightly to allow specifying the
additional "extra" command line parameters when creating the initial
seed nodes. Minor refactoring within the integration tests has been
undertaken in order to increase code re-use across tests.

Closes #29.

lnd: properly execute force closures kicked off via RPC
This commit includes some slight refactoring to properly execute force
closures which are initiated by RPC clients.

The CloseLink method within the htlcSwitch has been extended to take an
additional parameter which indicates if the link should be closed
forcefully. If so, then the channelManager which dispatches the request
executes a force closure using the target channel state machine. Once
the closing transaction has been broadcast, the summary is sent to the
utxoNursery so the outputs can be swept once they’re mature.
