TODO: support for wallet upgrades and key imports
This commit adds support for using StartTime in a rescan in
neutrino. The NeutrinoClient instance can have a birthday set
such that all underlying neutrino rescans are called with that
start time.
This commit allows neutrino to simulate the GetBlockHeader RPC, and
allows chain client code to use the call with both btcd/RPC back end
and the neutrino back end.
During the time of initial block hash catch-up, it is possible to
request an address be generated. This commit updates the active
addresses by calling `w.activeData` after the catch-up is complete.
This commit makes sure the wallet db is closed if the call to
open the wallet fails, as subsequent calls to OpenExistingWallet
would fail to open the already open database.
… sending

In this commit, we do away with the internal relayFee all together.
Instead, we’ll pass in the fee rate when we’re crafting any
transactions. This allows the caller to manually dictate their desired
fee rate.
This commit adds a new method EstimateVirtualSize that calculates
the worst case estimate vsize for a transaction with a given set
of inputs and outputs. This method is aware of P2PKH, P2WPKH and
P2SH-P2WPKH inputs, and caulculates the transaction vsize with
the witness data included.
This commit adds a test for EstimateVirtualSize. Currently three
test transactions are added:
    - 1 P2WPKH inputs + 2 P2PKH outputs
    - 1 P2SH-P2WPKH inputs + 2 P2PKH outputs
    - 1 P2WPKH inputs + 1 P2PKH output + 1 P2WPKH change output
This commit makes use of the recently added EstimateVirtualSize
method to estimated the size of a transaction when calculating
fees. This makes fee estimation more accurate when we are spending
segwit outputs, as before we wouldn't account for the witness
descount, resulting in overshooting fee estimates.

In this commit, we address an issue with the wallet where it would
always request a rescan from the birthday block. This is very crucial
for older wallets, as it'll potentially go through thousands of blocks.
To address this, we'll now only request a rescan from our birthday if
we're recovering our wallet from our seed, the birthday block was rolled
back, or if we're performing our initial sync. Otherwise, we'll request
a rescan from tip.
In this commit, we add a new key/value pair to the waddrmgr's sync
bucket to store the verification status of the birthday block. This
verification status determines whether the wallet has verified the
correctness of its birthday block through its sanity check on startup.
…ock has been verified

In this commit, we prevent any further sanity check attempts by the
wallet if its correctness has previously been verified. We do this to
ensure we don't unnecessarily attempt to find a new candidate.
…thin ImportPrivateKey

In this commit, we set the verified bit to false upon setting the new
birthday block to ensure its correctness as it was provided by the caller.
wallet/wallet: prevent always rescanning from birthday block
In this commit, we remove the wallet dependency from the
birthdaySanityCheck function. Every interaction with the wallet is now
backed by two interfaces, birthdayStore and chainConn. These interfaces
will allow us to increase the test coverage of the birthdaySanityCheck
as now we'll only need to mock out only the necessary functionality.
In this commit, we address an issue that would cause users to be stuck
in an infinite loop by fetching the same candidate birthday block due to
its height not being updated if the sanity check was attempting to fix
an estimate in the future. We fix this by setting the new candidate
height so that new candidate blocks can be fetched and tested.
wallet/chainntnfs: set height for new birthday block candidate
build: use latest btcd and neutrino
build: update to latest btcd and neutrino versions

Great work! Just some minor changes required 👍

Woud be nice to use a LTC specific block at height 100K
