zpay32/invoice: remove unknown required fbit check from decode
This commit removes the unknown required feature bit check from the
invoice decoding logic. This allows greater utility to users of the
decodepayreq rpc since it can provide inspection of otherwise invalid
invoices. In the prior commit, this check moved into our path finding
logic, so invalid features taken from an invoice will instead cause a
failure when attempting to pay.

routing/pathfind: ignore unknown required features
This commit brings us inline with recent modifications to the spec, that
say we shouldn't pay nodes whose feature vectors signal unknown required
features, and also that we shouldn't route through nodes signaling
unknown required features.

Currently we assert that invoices don't have such features during
decoding, but now that users can specify feature vectors via the rpc
interface, it makes sense to perform this check deeper in call stack.
This will also allow us to remove the check from decoding entirely,
making decodepayreq more useful for debugging.

feature/required: add ValidateRequired method
This wraps the raw UnknownRequiredFeatures method and returns a proper
error type to enable more exact testing.

routing: use updated sphinx.NewOnionPacket method
In this commit, we update the routing package to use the new
`sphinx.NewOnionPacket` method. The new version of this method allows us
to specify _how_ the packet should be filled before it's used to create
a mix-header. This isn't a fundamental change (totally backwards
compatible), instead it plugs a privacy leak that may have revealed to
the destination how long the true route was.

chanfitness: save initial online event for channels with online peers
This commit adds an initial peer online event for channels
that have peers that are online when they are created. This
addresses a race between the peer coming online and an
existing channel being added to the event store; if the
peer comes online first, the existing channel will not have
its initial online event added.

discovery: interpret block range from ReplyChannelRange messages
We move from our legacy way of interpreting ReplyChannelRange messages
which was incorrect. Previously, we'd rely on the Complete field of the
ReplyChannelRange message to determine when our peer had sent all of
their replies. Now, we properly adhere to the specification by
interpreting the block ranges of these messages as intended.

Due to the large number of nodes deployed with the previous method, we
still maintain and detect when we are communicating with them, such that
we are still able to sync with them for backwards compatibility.

discovery: remove unnecessary test check
It's not possible to send another reply once all replies have been sent
without another request. The purpose of the check is also done within
another test, TestGossipSyncerReplyChanRangeQueryNoNewChans, so it can
be removed from here.

signrpc: derive custom shared key
With this commit we add the ability to create a shared DH key by using
a custom node private key instead of the node's identity private key.
If no key locator is specified the node's identity private key will be
used as a fallback.

lnwallet/channel: reuse derived SingleTweak on local force close
When creating the keyring, the tweak is already calculated in the remote

we can use it in all cases without deriving the tweak.

lnwallet: use channel type to derive keys
We abstract away how keys are generated for the different channel types
types (currently tweak(less)).

Intention is that more of the logic that is unique for each commitment
type lives in commitment.go, making the channel state machine oblivious
to the keys and outputs being created on the commitment tx for a given
channel state.

lnwallet: return instead evaluated commitment instead of mutating
createCommitmentTx would earlier mutate the passed commitment struct
after evaluating the htlc view and calculating the final balances, which
was confusing since the balances are supposed to only be *after*
subtracting fees.

Instead we take the needed parameters as arguments, and return the final
balances, tx and fee to populate the commitment struct in a proper way.

lnwallet: pass chan cfgs to CreateCommitTx
Instead of passing delays and dustlimits separately, we pass the correct
channel config to CreateCommitTx from the POV of the local party that
owns the commit tx.

To make it more clear which commitment we are actually creating, we
rename variables to denote local and remote, to prepare for the case
when both outputs might be delayed.
