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`.
This commit introduces more granular statuses to better determine a
payment's current state. Based on whether there are inflight HTLCs, the
state of each of the HTLCs, and whether the payment is failed, a total
of 5 states are derived, which can give a finer control over what action
to take based on a given state.
Also, `fetchPayment` now uses `decidePaymentStatus`. After applying the
new function, the returned payment status would be different,
```
| inflight | settled | failed | reason | previous -> now |
|:--------:|:-------:|:------:|:------:|:---------------------------------:|
| true | true | true | yes | StatusInFlight(unchanged) |
| true | true | true | no | StatusInFlight(unchanged) |
| true | true | false | yes | StatusInFlight(unchanged) |
| true | true | false | no | StatusInFlight(unchanged) |
| true | false | true | yes | StatusInFlight(unchanged) |
| true | false | true | no | StatusInFlight(unchanged) |
| true | false | false | yes | StatusInFlight(unchanged) |
| true | false | false | no | StatusInFlight(unchanged) |
| false | true | true | yes | StatusSucceeded(unchanged) |
| false | true | true | no | StatusSucceeded(unchanged) |
| false | true | false | yes | StatusSucceeded(unchanged) |
| false | true | false | no | StatusSucceeded(unchanged) |
| false | false | true | yes | StatusFailed(unchanged) |
| false | false | true | no | StatusInFlight(unchanged) |
| false | false | false | yes | StatusFailed(unchanged) |
| false | false | false | no | StatusInFlight -> StatusInitiated|
```
This commit adds a new method, `Registrable`, to help decide whether
adding new HTLCs to a given payment is allowed. A new unit test,
`TestRegistrable` is also added to test it.
This commit adds a new payment status, `StatusInitiated`, to properly
represent the state where a payment is newly created without attempting
any HTLCs. Since the `PaymentStatus` is a memory representation of a
given payment's status, the enum used for the statuses are directly
updated.
