8e4199ee92 discovery+server: make waiting proofs persistent
In this commit waiting proofs array have been replaced with persistant
boltd storage which removes the possibility for the half proof to be
lost during half proof exchange.

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

server: properly add user initiated persistent conns to persistentPeers map
This commit fixes a prior bug wherein if a user connected to a peer
using the —perm command, then once the peer was disconnected, we
wouldn’t automatically connect to them.

chainntfns/btcdnotify: eliminate block epoch race condition, use diff cancel channel
This commit fixes a race condition that was uncovered by the race
condition detector surrounding cancelling active block epoch
notifications. Previously we would close the main notification channel
for each client, at tine this would cause a read/write race condition
if an active grouting was attempting to dispatch a notification. We now
fix this use by using a distinct channel for signaling cancellation to
the active grouting, and another to signal cancellation to any
notification observers.

1eaa522265 tests: add test case "disconnecting target peer"
Issue: 139

This commit contains test case "disconnecting target peer" (second test case) which takes two
connected peers, then checks via assert method one connection exists,
then disconnects this remote peer by passing pubKey parameter (just some string) into RPC-call method. Then checks 0
connection exists, and then connects disconnected peer for passing
further tests, and then checks one connection exists.

Issue: 139

server: fix regression in handling persistent connection requesrts
This commit fixes a bug that was introduced when the concurrent
connection handling logic was re-written: if we don’t properly add the
persistent outbound connection to the persistent conn reqs map. The fix
is easy: add the pending conn req to the proper map.

breacharbiter: at startup, watch pending closed channels to mark as fully closed
This commit adds a start up check to the breachArbiter: it will now
watch all channels which are in the “pending closed” state, to ensure
that state of the database is up to date at all times. Once any of the
closing transactions for these channels have been confirmed, then they
will properly be marked as such within the database.

peer: properly manage channel close lifecycle within the database
Within this commit the peer will now properly manage the channel close
life cycle within the database. This entails marking the channel as
pending closed either once the closing transaction has been broadcast
or the close request message has been sent to the other side.

Once the closing transaction has been confirmed, the transaction will
be marked as fully closed within the database. A helper function has
been added to factor out “waiting for a transaction to confirm” when
handling moth local and remote cooperative closure flows.

Finally, we no longer delete the channel state within wipeChannel as
this will now be managed distinctly by callers.

funding: fix bug that double counts "pending channels" in GetInfo
This commit fixes a bug that double counts the number of pending
channels in GetInfo. Previously we weren’t yet storing the pending
channels on disk, we are now but comparing both the disk channel and
the channels within memory leads us to double count channels. To fix
this, we now only count the database channels.

Note that this NumPendingChannels method can now be removed as it’s no
longer needed.

utxonursery: add new public NurseryReport method
This commit adds a new public facing method to the utxoNursery:
NurseryReport. This method is intended to be used by callers to
introspect into the current state of the utxo nursery. With this
information, callers will be able to ascertain: the number of immature
outputs, the total number of funds in limbo, and when funds can be
fully swept.

utxonursery: add to new index buckets to enable querying nursery state
This commit adds to new index buckets to the undo nursery: one that
allows searching the preschool bucket by origin chan point, and another
that allows querying the kindergarten bucket using an identical key.
These index buckets are updated in tandem with their regular buckets.

A note has been named in this commit to re-work the bucket structure
for a time in the near future in which we have implemented full
on-chain HTLC handling.

lnwallet: add distinct channel to send close details over
This commit modifies the actions of the closeObserver goroutine to
utilize a _new_ channel to send channel close details over. The
original close signal channel is still used to notify observers that a
channel _has_ been closed, but this new channel will provide a single
observer with details w.r.t _how_ a channel was closed.

lnrpc: augment the PendingChannels RPC to include details of closed channels
This commit adds some additional fields to the PendingChannels RPC s.t
users will be able to use the RPC to gain a complete view w.r.t where
all the funds within the daemon are, and how soon they can be
retrieved.

The following information is now returned:
   * all channels pending open
   * all channels pending cooperative close
   * all channels pending force close

server: only attempt to reconnect to peer if connection not pending
This commit fixes a bug that would possibly result in tens of goroutine
beaching launched in an attempt to persistently connect to a peer. This
bug has been fixed by ensuring that we’ll only launch a new pending
connection attempt if we don’t already have one pending.

channeldb: add new method to db, MarkChanFullyClosed
This commit adds a new method to the database which allows callers to
mark a channel as fully closed once certain conditions have been
reached. If a channel was cooperatively closed, then it can be marked
as fully closed as soon as the channel has been confirmed. If the
channel was marked as force closed, then it should be marked as closed
as soon as _all_ the funds in limbo have been swept.

channeldb: expand channel close summaries to include additional data
This commit expands the close summaries within the database to include
additional information such as: how the channel was closed, if the
channel if fully closed, and other balance information. This new
information will be used in an upcoming expansion of the
pendingChannels RPC to display more comprehensive data w.r.t where the
node’s funds are and how soon they’ll be fully available.

The data stored in the closeChannel bucket has been expanded to include
the above. Additionally the CloseChannel method on the OpenChannel
struct now takes in the additional information that details how and who
it was closed by.

This commit borrows heavily from the initial work in #179 by @halseth.

This commit fixes a bug introduced by the new multi-chain features of

Previously if two local nodes were set to, the _same_ chain, then
they’d both share the same chain data directory which would prevent one
of the nodes from being able to start up properly.
