rpc: enforce the max payment size as defined in BOLT-0002
This commit modifies the relevant RPC’s to enforce the max payment size
as defined in BOLT-0002. With this commit the largest payment possible
is now 2^32 mSAT, or 4,294,967 satoshis.

rpc: ensure the inner grouting within SendPayment will always exit
This commit adds a new reqQuit channel within SendPayment. The inner
goroutine will use this channel to detect if the request itself has
exited or not. Without this method, we’d possible leak a goroutine if a
client never closed the payment stream.

rpc: make NewWitnessAddress return np2wkh addresses
This commit modifies NewWitnessAddress to return nested p2wkh address.
We do this as this RPC call was put in place to be used within GUI’s to
allow users to deposit funds into their LN wallet. By using nested
p2wkh, we ensure that the generate address that can be used to directly
create channels.

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.

This commit ensures that we always clean up the resources that are
created when a new instance of a lnwallet.LightningChannel is
instantiated. The is necessary due to the sigPool that’s now present as

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.

6861df0e23 rpcserver: add additional 'error' field in payment response
In order to not close the payment stream on payment error the additional
field have been added in payment response. Now error from stream Recv()
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

    | (Switch)		        (Switch)		  (Switch)

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.

This commit allows users to sign messages with their node's private key

human readability/paste-ability.  Others users can verify that a message
was signed by another node in their channel database with the
VerifyMessage interface.

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

rpc: re-write GetNetworkInfo implementation to use single db transaction
This commit re-writes the GetNetworkInfo implenetaiton to use a single
database transaction. We’re now able to do this due to the recent
change in the API for the ChannelGraph struct and it’s related objects.
The recent change allows the passed callback to accept a db
transaction, with this, the callback is now able to issue another
traversal routine _within_ the prior one.

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.
