lnwallet: fully validate all channel constraints in validateCommitmentSanity
This commit introduces changes to the validateCommitmentSanity
function to fully validate all channel constraints.
validateCommitmentSanity now validates that the
MaxPendingAmount, ChanReserve, MinHTLC, & MaxAcceptedHTLCs
limits are all adhered to during the lifetime of a channel.

When applying a set of updates, the channel constraints are
validated from the point-of-view of either the local or the
remote node, to make sure the updates will be accepted.

lnwallet/channel: move common calculation of balance into computeView
This commit moves common logic used to calculate the state
of a commitment after applying a set of HTLC updates, into
the new method computeView. This method can be used when
calculating the available balance, validating the sanity
of a commitment after applying a set of updates, and also
when creating a new commitment, reducing the duplication
of this logic.

lnwallet/channel: let evaluateHTLCView take mutate boolean
This commit adds a new boolean parameter mutateState to
evalueteHTLCView, that let us call it without neccessarily
mutating the addHeight/removeHeight of the HTLCs, which is
useful when evaluating the commitment validity without
mutating the state.

htlcswitch: don't return negative value from Bandwidth()
This commits prevents the Bandwith() method from returning
a negative value if the channel reserve is larger than
the actual available balance.

lnwallet: cleanup of reservation.CommitConstraints, and move RemoteChanConstraints.
This commit adds some more comments and checks to
reservation.CommitConstraints, including making
MinHTLC value one of the passed constraints.

RemoteChanConstraints is also moved out of
reservation.

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.

htlcswitch/switch: select on quit channels for switch commands
This commit fixes a deadlock scenario caused when some
switch methods are waiting for a response on the
command's done/err chan. However, no such response will
be delivered if the main event loop has already exited.
This is resolved by selecting on the command's done/err chan
and the server's quit chan simultaneously.

breacharbiter: avoid infinite loop in exactRetribution
After a shutdown has been initiated, both registrations
for spend ntfns and publishing txns can fail. The current
behavior in the face of such failures is to continue trying,
which is fine if we are online. However, this causes an
infinite loop during shutdown, and lnd cannot exit since
the routine is tracked by the brar's waitgroup.

A simple fix is to select on the brar's quit channel after
detecting a failure from either, allowing the breach arbiter
to break out of this death cycle.

utxonursery: fix witness overwriting bug
Fixes a minor indexing bug that could cause the
utxonursery to accidentally overwrite CSV
witnesses with other CLTV witnesses when populating
a sweep txn. Each type of output is treated
separately internally, the bug is introduced by
using the relative indexes of both sets as the final
indexes into the txins.

The fix adds an offset, equal to the number of CSV
outputs, to the relative indexes of the CLTV inputs.
This matches the order in which CSV and CLTV outputs
are added to the raw txn.

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.

lnwire: replace instances of *btcec.PublicKey with [33]byte in ann messages
In this commit, we replace all instances of *btcec.PublicKey within the
announcement messages with a simple [33]byte. We do this as usually we
don’t need to immediately validate an announcement, therefore we can
avoid the scalar multiplications during decoding.

lnwire: add new Sig type to handle conversion to/from btcec.Signature
In this commit, we add a new signature type. We’ll use this type to
avoid fully decoding a signature on the wire into a btcec.Signature.
This type is only really needed when we need to do signature
validation, as a result, always encoding it is a waste. Several helper
methods have been added to the new struct in order to ensure that we
can use it in the existing codebase without substantial issues.
