409efd1361 channeldb/channel_test: add TestFetchWaitingCloseChannels
In this commit, we add a test case for FetchWaitingCloseChannels to
ensure it behaves as intended. Currently, this test fails due to not
fetching channels which are pending to be closed but are also pending to
be opened. This will be fixed in the following commit and should allow
the test to pass.

f6c02aec20 channeldb/channel_test: use random outpoint when creating new test channels
In this commit, we use random outpoints when creating new test channels
to ensure we can uniquely identify them.

channeldb: update ChannelView to return new EdgePoint struct
In this commit, we update the ChannelView method to be compatible with
the new set of interfaces that require the script to be passed in in
addition to the outpoint. In order to do this, we introduce a new
EdgePoint struct which packages together a channel point along with the
funding pkScript. Along the way, we've copied over a utility method from
the lnwallet package to avoid having to deal with an import cycle.

channeldb/channel_test: test ShortChanID is updated in-mem
Modifies TestFetchPendingChannels to verify that calls to
MarkAsOpen also modify the in-memory state. Previously we
only tested the persistent state loaded immediately after.

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: 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.

channeldb: expand TestChannelStateTransition to expertise new state transition related methods
In this commit we’ve extended the TestChannelStateTransition method to
exercise the new state transition related messages. This includes
ensuring that when we add a new dangling commitment, and then the
remote party revokes it, then the on-disk state is update accordingly.

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.

channeldb: replace opening height will short chan ID in OpenChannel
This commit modifies the OpenChannel struct to include the full short
channel ID rather than simply the opening height. This new field will
be needed by an upcoming change to uniformly switch to using short
channel ID’s when forwarding HTLC’s due to the change in per-hop
payloads.

channeldb: store the funding transaction broadcast height for channels
This commit expands the field within the OpenChannel struct in order to
start tracking the height that the funding transaction was initially
broadcast. Other sub-systems within lnd can now use this data to give a
more accurate height hint to the ChainNotifier, or to use during the
funding workflow to decide if a channel should be forgotten after it
fails to confirm for N blocks.

channeldb: change MinFeePerKb to FeePerKw in OpenChannel struct
This commit modifies the name of a field in the OpenChannel struct to
better reflect its actual usage within this protocol. The FeePerKw
represents the amount of satoshi to be paid as fees per kilo-weight.
This field is set at the opening of a transaction and will be able to
be updated properly via the usage of the update_fee method.

channeldb: add total time locked balance to CloseChannelSummary
This commit adds the total time locked balance of a closed channel at
closure time to the CloseChannelSummary struct. With this information,
we now provide sub-systems within the daemon further knowledge which
can aide them in properly handling querying for the state of pending
close transactions, or if they should watch a channel for closure or
not.

This commit adds a new method to the channel state: RevocationLogTail.
This new method will return the information concerning the latest
revoked state of the remote party’s commitment chain.

This new data can be used to properly initialize the states of the
in-memory commitment chains on node start up.

f86557c3e4 channeldb+lnwallet: replace elkrem with shachain
In this commit the initial implementation of revocation hash
generation 'elkrem' was replaced with 'shachain' Rusty Russel
implementation which currently enshrined in the spec. This alghoritm has
the same asymptotic characteristics but has more complex scheme
to determine wish hash we can drop and what needs to be stored
in order to be able to achive full compression.

channeldb: fix bug when writing revocation log states
This commit fixes a bug that was introduced when we moved to using
64-bit integers for storing the revocation log state. When we made this
change, we forgot to increase the size of the buffer which stores the
key for the particular channel state from 40 to 44 bytes to account for
the 4 additional bytes in the new 64-bit integer.

This bug has been fixed by properly sizing the key buffer. We’ve also
added an additional test to ensure that we retrieve the proper state
after multiple state updates.

channeldb: ensure all state is deleted for a channel by CloseChannel
This commit addresses some lingering TODO’s which ensure that related
state to a channel is properly deleted by the CloseChannel method.
Previously the values for the respective dust-limits of either side,
the on-disk HTLC’s, and any entries the revocation log for the channel
weren’t being properly deleted.

Additionally, we now modify the checks within the unit tests to ensure
that we can still read the channel from disk w/o running into an error
(thought the slice will be blank), and also the the revocation log is
properly garbage collected.

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.
