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.

discovery: cover requested range in ReplyChannelRange messages
In order to properly adhere to the spec, when handling a
QueryChannelRange message, we must reply with a series of
ReplyChannelRange messages, that when consumed together cover the
entirety of the block range requested.

discovery: use inclusive range in FilterChannelRange
FilterChannelRange takes an inclusive range, so it was possible for us
to return channels for an additional block that was not requested.

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
commitment case. We add the calculation also for our own commitment, so
we can use it in all cases without deriving the tweak.

lnwallet: use channel type to derive remote script
Based on the current channel type, we derive the script used for the
to_remote output. Currently only the unencumbered p2wkh type is used,
but that will change with upcoming channel types.

lnwallet: nil single tweak when creating keyring
To make the channel state machine less concerned about the type of
commitment, we nil the local tweak when creating the keyring, depending
on the commitment type.

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: rename DelayKey->ToLocalKey, NoDelayKey->ToRemoteKey
Since both parties are going to have their ouputs delayed, we move way
from the DelayKey naming, and instead use ToLocalKey and ToRemoteKey.

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.

We move the methods and structs to a new file commitment.go in
preparation for defining all the logic that is dependent on the channel
type in this new file.

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.

channeldb+lnwallet: note that balance is after subtracting commit fee
It was incorrectly stated that the commitment balance was before

lntest: fix macaroon paths
This change makes sure that all macaroons are stored in the same
folder. This makes it possible to use the lntest package in external
projects that use loop's lndclient library which currently assumes
that the admin macaroon and subserver macaroons are in the same sub
folder of lnd's data directory.

invoices: jit insert key send invoices
This commit adds handling code for the key send custom record. If this
record is present and its hash matches the payment hash, invoice
registry will insert a new invoice into the database "just in time". The
subsequent settle flow is unchanged. The newly inserted invoice is
picked up and settled. Notifications will be broadcast as usual.

channeldb: update payment request comment
This field isn't optional. It was introduced in
5ed31b1030176374d4184fee0b80ae7679e0e355 which was part of release
0.4.0. This release contained breaking database changes, so it is safe
to assume that from there on the field is always populated.

If there would still be empty payment request fields in the wild, users
would also experience issues with ListInvoices. ListInvoices decodes the
payment request.
