This commit refactors the params used in lifecycle to prefer
`HTLCAttempt` over `HTLCAttemptInfo`. This change is needed as
`HTLCAttempt` also wraps settled and failure info, which is useful in
the following commits.
This commit turns `MPPayment` into an interface inside `routing`. Having
this interface gives us the benefit to write more granular unit tests
inside payment lifecycle. As seen from the modified unit tests, several
hacky ways of testing the `SendPayment` method is now replaced by a mock
over `MPPayment`.
This commit adds a new method, `NeedWaitAttempts`, to properly decide
whether we need to wait for the outcome of htlc attempts based on the
payment's current state.
This commit moves the struct `paymentState` used in `routing` into
`channeldb` and replaces it with `MPPaymentState`. In the following
commit we'd see the benefit, that we don't need to pass variables back
and forth between the two packages. More importantly, this state is put
closer to its origin, and is strictly updated whenever a payment is read
from disk. This approach is less error-prone comparing to the previous
one, which both the `payment` and `paymentState` need to be updated at
the same time to make sure the data stay consistant in a parallel
environment.
This commit moves the creations of hop and htlcAdd message from
`createNewPaymentAttempt` to `sendPaymentAttempt` to clean up the code
and further pave the way to decomposite the lifecycle.
This commit updates the `fee()` method in `weightEstimator` to make sure
when doing CPFP we are not exceeding the max allowed fee rate. In order
to use the max fee rate, we need to modify several methods to pass the
configured value to the estimator.
When one of the itest tranches fails, because we are running tests in
parallel, other tranches will still be running, which caused 7z to fail
at zipping the logs because race reads. This commit fixes it by making
sure we are waiting other tranches to finish before moving to zipping
and uploading the logs.
For about a year [1], the spec has prescribed encoding channel_updates
with their type prefix (0x0102) in onion failure messages. LND can
decode correctly with or without the prefix but hasn't been writing the
prefix during encoding. This commit starts writing the prefix.

This commit removes the `Litecoin`, `LtcMode` and `LitecoindMode`
members from the main LND `Config` struct. Since only the bitcoin
blockchain is now supported, this commit also deprecates the
`cfg.Bitcoin.Active` config option.
This commit applies the new method `Terminated`. A side effect from
using this method is, we can now save one query `fetchPayment` inside
`FetchInFlightPayments`.
