lnwallet/btcwallet: grab best header timestamp directly from wallet
In this commit, we modify the way we obtain the current best header
timestamp. In doing this, we fix an intermittent flake that would pop
up at times on the integration tests. This could occur as if the wallet
was lagging behind the chain backend for a re-org, then a hash that the
backend knew of, may not be known by the wallet.

To remedy this, we’ll take advantage of a recent change to btcwallet to
actually include the timestamp in its sync state.

lnd: use first key in keychain.KeyFamilyNodeKey as our nodeID
In this commit, we update lnd to now access the deterministic
keychain.KeyRing struct in order to obtain our identity public key.
With this change, if the user recovers their wallet with the same seed,
then they’ll have access to the same prior node identity. This change
also makes it easy for us to support node key rotation in the future by
bumping up our requested index.

lnwallet: remove p2pkh as an address type, wallet is now pure segwit
In this commit, we modify the mechanics of the wallet to only allow
derivation of segwit-like addresses. Additionally, the ConfirmedBalance
method on the WalletController now only has a single argument, as it’s
assumed that the wallet is itself only concerned with segwit outputs.

lnwallet: modify the way we derive revocation roots to be deterministic
In this commit, we modify the way we generate the secrets for
revocation roots to be fully deterministic. Rather than use a special
key and derive all sub-roots from that (mixing in some “salts”), we’ll
use the proper keychain.KeyFamily instead. This ensures that given a
static description of the channel, we’re able to re-derive our
revocation root properly.

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.

lnwallet: update the SignDescriptor struct to use keychain.KeyDescriptor
In this commit, we update the SignDescriptor struct to instead use the
keychain.KeyDescriptor struct inplace of a raw public key. We do this
as this allows for a recovery mode, where the caller doesn’t know what
key was used exactly, but remembers the precise KeyDescriptor. A
stateless signer is still able to re-derive the proper key, as it’s
given the full path.

lnwallet/btcwallet: update implementation to account for recent API changes
The new version of the internal core of btcwallet now uses KeyScopes
rather than address types to derive particular addresses. As a result,
in this commit, we update our API usage to ensure that proper addresses
are still derived.

lnwallet: remove NewRawKey and FetchRootKey from the WalletController interface
In this commit, we remove two methods from the WalletController
interface which were previously used by the funding reservation process
(NewRawKey) and the p2p network (FetchRootKey) in order to derive
various keys for operation. This methods are no longer necessary as the
KeyRing interface implements the functionality in a deterministic
manner.

keychain: introduce new package for deterministic key derivation + seed
In this commit, we add a new package to lnd: the keychain package. The
role of this package is to house all the interfaces that lnd will use
to generate the various keys it needs to create contracts and operate
within the network. Additionally, we also use this package to define a
deterministic key derivation scheme, that can be implemented by any
software/hardware that partially understands BIP43-like derivation.

The first version (v0) of the keychain schema is very simple. We re-use
BIP43, with a slight twist. Re-using BIP43 lets us leverage all the
existing libraries out there as far as compatibility. The purpose used
is 1017, and the coin type, the particular coin type of the chain where
the keys are meant to be used. Within our schema, we define multiple
“key families”. Each key family is actually just manifested as a new
“account” within the BIP44/43 family. With this schema, if we have
static description of the keys used within a channel, given the seed,
and the “KeyLocator”, we can re-derive all keys necessary be able to
re-sign for the channel.

funding: only send know errors across wire
This commit changes the failFundingFlow to accept an error, which will
only be sent to the remote the peer if it is among the
ReservationErrors or ErrorCode. This is done to ensure we don't send
errors that contain information we don't want to leak.

lnrpc: add ForwardingHistory for querying payment circuit time series
In this commit, we add a new method to the RPC service:
ForwardingHistory. This method will allow callers to query for the
completed payment circuits in a particular time slice, skip a series of
events, and also paginate within a time slice.

htlcswitch: add new ticker in switch to batch log forwarding events
In this commit, we extend the switch as is, to record details
concerning settled payment circuits. To do this, we introduce a new
interface to the package: the ForwardingLog. This is a tiny interface
that simply lets us abstract away the details of the storage backing of
the forwarding log.

Each time we receive a successful HTLC settle, we’ll log the full
details (chans, fees, time) as a pending forwarding log entry. Every 15
seconds, we’ll then batch flush out these entries to disk. When we’re
exiting, we’ll try to flush out all entries to ensure everything gets
recorded to disk.
