f594a57c94 lnwallet: remove need for lnwallet to have access to the private key
This paves the way for lnd to work with hardware wallets, in which case it will not have access to the private key.

lnwallet: add test to execrise unconfirmed transcations notified by SubscribeTransactions
In this commit, we add a new test to ensure that all backends will
properly send out notifications when an unconfirmed transcation that we
send is inserted into the tx store. Before we updated the btcwallet
build commit in dep, this would fail for neutrino but now passes.

lnwallet: fix ListTransactionDetails to ensure unconfirmed transactions are installed
In this commit, we fix a bug in the arguments to GetTransactions for the
btcwallet implementation of the WalletController interface. Before this
commit, we wouldn't properly return unconfirmed transactions. The issue
was that we didn't specify the special mempool height of "-1", as the
ending height. The mempool height is actually internally converted to
the highest possible height that can fit into a int32.

In this commit, we set the start to zero, and end to -1 (actually
2^32-1) to properly scan for unconfirmed transactions.

Fixes #1422.

lnwallet: add test to ensure that all backends show unconf txns in ListTransactionDetails
In this commit, we add a new test to the set of lnwallet integration
tests. In this new test, we aim to ensure that all backends are able to
display unconfirmed transactions in ListChainTransactions. As of this
commit, this test fails as no backends will return unconfirmed
transactions properly.

lnwallet: ensure that each backend uses a distinct seed in integration tests
In this commit, we add an additional degree of isolation to the set of
integration tests. A bug was recently fixed to ensure that the wallet
always starts rescans from _after_ it's birthday. In the past it would
miss some funds that were deposited _right_ before the birthday of the
wallet. Fixing this bug exposed a test flake wherein the btcd node would
itself rescan back and collect some of the funds that were last sent to
the bitcoind node.

In order to fix this, we now ensure that each backend will use a unique
HD seed such that the tests are still deterministic for each backend and
role.

b06dabfcb9 lnwallet: properly set auxiliary channel recovery info in NewUnilateralCloseSummary
In this commit, we fix a slight bug by ensuring that the revocation info
at the final state of the channel, as well as the local chan config is
properly set within the channel close summary created within
NewUnilateralCloseSummary. Before this commit, for all cooperative close
transactions, this state would _only_ include the pubkey itself, which
in some cases may not be sufficient to re-derive the key if needed.

multi: switch to transaction weight to calculate transaction fees
Due to a recent change within the codebase to return estimated fee rates
in sat/kw, this commit ensures that we use this fee rate properly by
calculing a transaction's fees using its weight. This includes all of
the different transactions that are created within lnd (funding, sweeps,
etc.). On-chain transactions still rely on a sat/vbyte fee rate since it's
required by btcwallet.

lnwallet: switch fee estimation to return sat/kw fee rates
In this commit, we modify our FeeEstimator interface to return an
estimated fee rate in sat/kw. Recently, due to low fees on the network,
users have been experiencing failures broadcasting transactions due to
not meeting specific fee requirements. This was happening more often
than not, as the estimated fee returned by backend nodes (bitcoind and
btcd) only takes into account vbytes, rather than weight. The fees
returned are also expressed in sat/kb, so we must take care that we do
not lose precision while converting to sat/kw. In the event that this
happens, a fee floor of 253 sat/kw has been added. This fee rate
originates from bitcoind rounding up the conversion from weight to
vbytes.

multi: update to latest BitcoindClient interface
In this commit, we introduce a nice optimization with regards to lnd's
interaction with a bitcoind backend. Within lnd, we currently have three
different subsystems responsible for watching the chain: chainntnfs,
lnwallet, and routing/chainview. Each of these subsystems has an active
RPC and ZMQ connection to the underlying bitcoind node. This would incur
a toll on the underlying bitcoind node and would cause us to miss ZMQ
events, which are crucial to lnd. We remedy this issue by sharing the
same connection to a bitcoind node between the different clients within
lnd.

lnwallet/channel: enumerate error cases from remote chain desync
This commit enumerates the various error cases we can encounter when we
compare our remote commit chain to the view the remote communicates to us
via msg.NextLocalCommitHeight.

We now compare this height to our remote tail and tip height, returning
relevant error in case of a unrecoverable desync, and re-send a
commitment signature (including log updates) in case we owe one.

This commit enumerates the various error cases we can encounter when we
compare our local commit chain to the view the remote communicates to us
via msg.RemoteCommitTailHeight.

We now compare this height to our local tail height (note that there's
never a local "tip" at this point), returning relevant error in case of
a unrecoverable desync, and re-send a revocation in case we owe one.

lnwallet + funding: move funding tx publish to fundingmgr
This commit moves the responsibility for publishing the funding tx to
the network from the wallet to the funding manager. This is done to
distinguish the failure of completing the reservation within the wallet
and failure of publishing the transaction.

Earlier we could fail to broadcast the transaction, which would cause us
to fail the funding flow. This is not something we can do directly,
since the CompeteReservation call will mark the channel IsPending in the
databas.e
