This is a hack fix to unblock lbrypool.net.
The paytxfee in lbcwallet is actually not being used anywhere, and is
hardcoded to DefaultRelayFee, which is 1000. Lbrycrd sets default to 0.
Also, since the paytxfee is not actually used/implemented, the
'settxfee' RPC is also
With this commit we refactor the existing script address into a
baseScriptAddress struct and then add a new witnessScriptAddress type
that manages a pay-to-witness-script address.
Since CT can mean both Cipher Text as well as Clear Text, the variable
name scriptCT lead to confusion about its meaning. We rename it to make
it more clear how it's used.
In this commit, we fix the peer selection for the pruned block
dispatcher. Turns out that the bits are actually mutually exclusive: a
node can set the network bit _and_ the limited (pruned bit).
The prior logic would only seek out "pure" nodes, meaning older nodes
that wouldn't set the limited bit when they're a full-full node. We fix
this by ignoring the limited bit, and we'll only look at the network and
segwit bits.
A unit test has also been added to show the issue in the prior filter
function.

The loadAccountInfo does load an account as its name suggests. But after
loading it, the account is also added to a map to cache it. That map
write should be seen as a writing operation and therefore the _write_
lock must be held, not just the read lock.
If SendOutputs is called on a watch-only wallet then a transaction is
created but without any signatures. Publishing that transaction will
always fail. But the attempt to publish will already update the internal
state of the wallet so we shouldn't try to publish this unsigned TX.
Instead we return a new error along with the unsigned transaction to
give the caller the chance to sign and publish it through other means.
If we're running in watch-only mode, there is no unlock possible.
Therefore, we also don't need to prevent any unlocks from happening when
doing coin selection in that mode.
In this commit, we add a new method `DeriveFromKeyPathCache` that gives
callers a way to more quickly obtain a private key they know they'll be
using frequently. This method lets a caller avoid the write database
transaction as well as the EC operations to derive the key itself (BIP
32).
To allow a wallet to be created directly from an extended master root
key (xprv), we move the derivation from seed to extended key to the
loader instead of the address manager itself.
We can now get rid of our incorrect dust calculation which did not
give exact values for segwit outputs as it was based on spending a
P2PKH output instead.
We want to make sure that every database backend has their own
implementation of the View() and Update() methods to make sure any
custom retry/commit/rollback strategies are used even when invoked
through the package-provided View() and Update() functions.
To make sure we don't create any manual DB transactions, we refactor the
txToOutputs method to use walletdb.Update and the new
walletdb.ErrDryRunRollBack error for making sure a rollback is issued.
