channeldb/channel: add property ChanStatus in place of IsBorked to OpenChannel
This commit changes the bool `IsBorked` in OpenChannel to a `ChanStatus`
struct, of type ChannelStatus. This is used to indicated that a channel
that is technically still open, is either borked, or has had a
commitment broadcasted, but is not confirmed on-chain yet.

The ChannelStatus type has the value 1 for the status Borked, meaning it
is backwards compatible with the old database format.

channeldb: update chanid in-mem during MarkAsOpen
Modifies the MarkAsOpen operation to also update the
ShortChanID and IsPending fields in-memory. Before,
only the on-disk representation was updated, which
may have lead to stale data channel states being
passed in-memory.

channeldb: replace raw keys in ChannelConfig with keychain.KeyDescriptor
In this commit, we remove references to raw keys from the main
ChannelConfig struct and instead replace it with usage of
keychain.KeyDescriptor. We do this, as the ChannelConfig as it stands
is a near complete static description of a channel. In the future, it
will be possible to export these static descriptions as backups. We
prefer the KeyDescriptor of a plain PublicKey, as the KeyLocator
portion of the struct allows a stateless signer to re-derive the keys
as needed when signing.

channeldb: add new ForwardingLog storage namespace
In this commit, we add a new storage namespace to channeldb: the
ForwardingLog. This log will be used by higher level sub-systems to log
each successfully completed HTLC. Each payment circuit will be
summarized as a “ForwardingEvent”. A series of events can then be
queried via a time slice query. In a time slice query, the caller
specifies a time range, a number of events to skip, and the max number
of events to return. Each query will return the index of the final
item. As we have a max number of events we’ll return in a response,
callers may need to use this last offset index to seek further by
skipping that number of entries. Combining these fields, callers are
able to query the time series, skipping an arbitrary amount of events,
and capping the max number of returned events.

channeldb: further GC optimizations during path finding
In this commit, we made a series of modification to the way we handle
reading edges and vertexes from disk, in order to reduce the amount of
garbage generated:
  1. Properly use PubKeyBytes are required rather than PubKey()
  2. Return direct structs rather than pointers, and leave it to the
runtime to perform escape analysis.
  3. In-line the former readSig() method when reading sigs from disk.

channeldb: update ChannelConstraints godoc
This commit changes the definition of the
constraints in the ChannelConstraints struct
to specify that these are all constraints the
*owner* of the set of constraints must *never
violate*.

This is done to make it easier to check that
a particular node is not violating any
constraint for a gien update, as before it
could violate constraints found both in its
local and the remote contraints.

channeldb: use raw pub keys and signatures directly in vertex/edge structs
In this commit, we make an API change that’s meant to reduce the amount
of garbage we generate when doing pathfinding or syncing nodes with our
latest graph state. Before this commit, we would always have to fully
decode the public key and signatures when reading a edge or vertex
struct. For the edges, we may need several EC operations to fully
decode all the pubkeys. This has been seen to generate a ton of
garbage, as well as slow down path finding a good bit.

To remedy this, we’ll now only ever read the *raw* bytes from disk. In
the event that we actually need to verify a signature (or w/e), only
*then* will we fully decode everything.

e2142c778f multi: Added Tor support
This commit adds Tor support. Users can set the --TorSocks flag
to specify which port Tor's SOCKS5 proxy is listening on so that
lnd can connect to it. When this flag is set, ALL traffic gets
routed over Tor including DNS traffic. Special functions for
DNS lookups were added, and since Tor doesn't natively support
SRV requests, the proxySRV function routes connects us to
a DNS server via Tor and SRV requests can be issued directly
to the DNS server.

channeldb: properly use a read-transaction in FetchChannelEdgesByOutpoint
Before this commit, we’d unnecessarily use a write transaction within

0f161c5033 channeldb+lnrpc: store the payment pre-image not rhash
Fixes #481.

Prior to this commit, payments stored in the channel DB only kept a
record of the payment hash. This is a problem as the preimage is what
serves as proof of payment and a user should be able to look up this
value in the future (not just immediately after payment).

Instead of storing both the payment hash and the preimage, we store the
preimage only since the hash can be derrived from this using a SHA256.

In the RPC listpayments command, we now give the preimage in addition to
the payment hash.

channeldb: properly craft key for reading/writing channel commitments
In this commit, we fix an existing bug that arose due to incorrectly
crafting the key we use to store channel commitments. Before this
commit, we tried to copy to a slice that hadn’t been allocated yet. As
a result, the key would only have the 0x00 or 0x01 as its value. We fix
this by properly crafting the key using the built-in append function.

In this commit we finalized the structure of the CommitDiff struct by

locked-in with the new commitment state. We include the LogIndex along
with the wire messages itself in order to be able to properly
reconstruct the update log upon restart.

The CommitSig message included should be transmitted after the set of
LogUpdates, and fully covers the new commitment state and any new (or
already present) HTLC’s that were included as part of the state.

In this commit we comptely overhaul the existing storage of the
OpenChannel struct to use the new common serialization defined within
the codec.go file. Additionally, we’ve modified the structure of the
channel database on disk. Rather then use the existing prefix based
segmentation, everything is now bucket based. This has resulted in much
simpler and easier to follow code. The bucket progression is:
openChannelBucket -> nodeBucket -> chainBucket -> channelBucket. We add
a chainBucket as it’s possible that in the future we may have several
channels on distinct chains with a given node.

With the above changes, we’re able to delete much of the existing code
within the file, drastically reducing its size.

This commit adds the method DisconnectBlockAtHeight to the channel

a prune log is introduced, making it possible to keep track of the

the case where lnd might wake up on a stale branch, and must "walk
backwards" on this branch after it finds a common block fro the
graph database and the new main chain.

916ab454c1 channeldb: Fix payment serialization tests.
This modifies the tests that deal serializing the Invoice type to limit
the creation date to seconds since Go1.9 added the concept of a
monotonic component to times which does not round trip through
MarshalBinary and UnmarshalBinary and therefore causes the tests to fail.

In particular, it modifies the creation dates in the randInvoice,
makeFakePayment, makeRandomFakePayment, and TestInvoiceWorkflow
functions.

This results in allowing TestOutgoingPaymentSerialization,
TestOutgoingPaymentWorkflow, and TestInvoiceWorkflow to pass.

channeldb: in node.ForEachChannel return incoming/outgoing edges
This commit modifies the node.ForEachChannel to *also* return the
incoming edge as well as the outgoing edge. We make this modification
as when we’re doing path finding, we need to return the incoming edge
as well, since we need to use the to properly compute the time lock and
fees for transit on that edge.

849d0b93b1 fundingManager: persist state in opening process.
Persists the state of a channel opening process after funding
transaction is confirmed. This tracks the messages sent to
the peer such that the process can be continued in case of a
restart. Also introduces that the receiver side forgets about
channel if funding transaction is not confirmed in 48hrs.

bd0465ee1d channeldb: support adding partial LightningNodes to graph.
Adds a HaveNodeAnnouncement field to the LightningNode
struct, which is used to indicate if we have gotten
all the necessary information to fill the remaining
fields in the struct. If we haven't gotten a node
announcement for this specific node, then we only
know the pubkey, and can only fill that field in
the struct. Still, we should be able to add it to the
channel graph and use it for routes, as long as we
know about channels to this node.

channeldb: remove RevocationDelay field from the HTLC struct
This commit removes the RevocationDelay field from the HTLC struct as
with the latest commitment transaction scheme, it is no longer needed.
This is due to the fact the the delay is now observed when an on-chain
HTLC claim is attempted, rather than from Shane the HTLC itself has
been broadcast.
