rpc: only set balance params when force closing if output not dust
This commit fixes an existing bug that would cause a force closed
channel to stay pending forever. In this instance, if one force closes
a channel while they have a dust output, and restart before the channel
is fully closed, then it wouldn’t have been closed automatically
(within the database) by the autopilot agent.

rpc: ensure db is updated on force close if no outputs to sweep
This commit fixes an issue where if a party force closing a channel,
doesn’t have a non-dust balance, nor any outgoing HTLC’s, then the
channel would never be marked as fully closed within the database.

We ensure that this case is addressed, by inserting a checking to
determine if we have any funds to sweep, marking the channel fully
closed on initial commitment transaction confirmation if not.

rpc: ensure that calls that depend server are rejected if server not active
This commit adds a bit of a guard to a set of RPC calls. If an RPC call
needs to interact with the server but it hasn’t yet been started. Then
we’ll exit early in order to avoid blocking the call until the server
itself has started.

A recent change to the initialization order of sub-systems within lnd
results in a state where the daemon will wait for the wallet itself to
finish syncing _before_ the server is started. This was interpreted as
a bug by some users, so we’ll make the state of the server more
explicit by returning an error.

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.

rpc: fix bug in GetNetworkInfo that causes NaN outputs in JSON
Previously the integers would either underflow or the floating point
division would result in odd numbers if a node knew of zero channels
within the network graph. We now fix this situation by checking to see
if any channels exist before computing the network stats.

Fixes #211.

In order to not close the payment stream on payment error the additional

function means that something has happend inside the client and we unable
to process any payment farther, and error inside the payment response
means, that something wrong has happend with payment itself.

c4955258f1 htlcswicth: start use htlcswitch and channel link inside lnd
In current commit big shift have been made in direction of unit testable
payments scenarios. Previosly two additional structures have been added
which had been spreaded in the lnd package before, and now we apply
them in the lnd itself:

1. ChannelLink - is an interface which represents the subsystem for
managing the incoming htlc requests, applying the changes to the
channel, and also propagating/forwarding it to htlc switch.

2. Switch - is a central messaging bus for all incoming/outgoing htlc's.
The goal of the switch is forward the incoming/outgoing htlc messages
from one channel to another, and also propagate the settle/fail htlc
messages back to original requester.

With this abtractions the folowing schema becomes nearly complete:

abstraction

rpc: non-existence of a nursery report is no longer an error
This commit fixes a slight logic error that could render the
`pendingchannels` RPC unusable if a node was on the reciting end of a
channel force close with no time-locked balance. In such a case the
channel wouldn’t be sent to the utxoNursery, resulting in an “contract
not found error”.

To fix this behavior, we’ve created a typed error that can be checked
within the RPC, thus we no longer treat this routine case as an error
case.

rpc: modify DisconnectPeer implementation to do all validation within rpcServer
This commit modifies the implementation of the new DisconnectPeer RPC
in the following ways:
   * all validation has moved from the server to the rpcserver
   * rather than iterating over _all_ channels, we now only check the
     peer’s channels
   * the disconnectPeerMsg now has a public key object
      * this allows us to also verify that the user submitted a valid
        pub key string
   * we now check if a peer was persistent when disconnecting so we can
     remove them from the persistent peer map

rpcserver: use semaphore to limit # of goroutines in SendPayment
This commit fixes a prior oversight in the implementation of
SendPayment that could result in tens of thousands of goroutines
OOM’ing an lnd daemon. Previously we didn’t limit the number of
outstanding payments that were allowed by a client. Users on machines
with a small amount of RAM were reporting crashes when sending a very
large number of payments in a consistent stream. This commit fixes this
issue by now using a semaphore to limit the number of outstanding
payments (and therefore) goroutines allowed in the SendPayment method.

rpc: properly detect case where remote party closes unknownst to us
This commit addresses an edge case which has been discovered by testers
of lnd of testnet. When/if channels get out of sync the unilateral
channel closure of a remote node may go undetected, which causes the
local node to lose their ability to purge the now closed channel from
their database state.

With this commit, if we try to force close a channel but detect it as
double-spent due to a prior commitment transaction being broadcast,
then we simply forget the channel as it has already been closed.

This commit moves much of the logic for querying for a potential route,
constructing the HTLC including the Sphinx packet, and sending the
ultimate payment from the rpcServer to the ChannelRouter.

This movement paves the way for muilt-path path finding as well as

having the ChannelRouter construct the Sphinx packet, we’ll be able to
also include the proper time-lock and general per-hop-payload
information properly in the future.

individual send. When sending a set of messages to a target peer, we
now give up the mutex as soon as we’ve access the map, rather than
holding onto it until the sending is complete.

rpcserver: add a min channel size for funding requests
This commit adds a soft-limit for the minimum allowed channel size.
Without this limit a user may inadvertently create an invalid or
unspendable output due to the hard coded fees in a few areas of the
codebase.

This is a temporary measure, and will be removed once we add dynamic
fees into the mix.

rpcserver: return full path payments go over in SendPayment
This commit augments the server’s response to successful SendPayment
commands by also returning the full path taken in order to fulfill the
payment. With this information, the user now obtains more context about
their payment whcih can be useful when debugging, or just exploring the
capabilities of the daemon.

rpcserver: allow channels to be opened using --node_id
This commit fixes a slight bug in the interaction between the cli
program and the rpcsever itself. With this commit it’s now again
possible to create a channel with a peer that’s identified by its
peerID, instead of only the pubkey.

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.

rpcserver: refactor logic for ListPayments/DeleteAllPayments
This commit slightly refactors the logic for the new outgoing payment
related RPC’s to more closely match the style of the rest of the
codebase. Additionally the tests have been updated to reflect the
changes to the protos of the new RPC’s.

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.
