This commit adds the --stateless_init flag to all three wallet unlocker
operations. Once you initialize a wallet stateless, you need to set
this flag for every further wallet unlocker operation. Otherwise you
risk non-encrypted macaroon information to leak to the underlying
system.
Similarly as with kvdb.View this commits adds a reset closure to the
kvdb.Update call in order to be able to reset external state if the
underlying db backend needs to retry the transaction.
This commit adds a reset() closure to the kvdb.View function which will
be called before each retry (including the first) of the view
transaction. The reset() closure can be used to reset external state
(eg slices or maps) where the view closure puts intermediate results.
Without this change the high-fee logic is never tested as it is instead caught by the dust-output logic. This change uses a higher fee rate to ensure an output value above the dust limit, while still spending 20% on fees.
To allow nodes more control over the amount of time that their funds
will be locked up, we add a MaxLocalCSVDelay option which sets the
maximum csv delay we will accept for all channels. We default to the
existing constant of 10000, and set a sane minimum on this value so that
clients cannot set unreasonably low maximum csv delays which will result
in their node rejecting all channels.
To make sure the test that takes the longest overall time is always
started first, independent of the number of test tranches we run, we
move it to the beginning of the list. Because that test involves a lot
of waiting, it allows us to play around with the number of tranches more
efficiently.
Updating the fee of the mock estimator _after_ starting carol turned out
to be flaky and could lead to the new fee not being picked up in time
for the force close. That lead to carol not cpfp'ing the force closed
transaction.
To allow running multiple test tranches in parallel, we need a way to
make sure the TCP ports don't collide. We'll work with offsets for the
ports, using a different offset for each tranche.
A user complained about getting a misleading error after a typo in the
mnemonic. The word was `hear` and it passed the check even when it is
not in the list of valid words.
The reason is that we where checking if the word is in the variable
`englishWordList` (which includes all the words) instead of checking if the
variable is in the `defaultWordList` (which is basically `englishWoldList`
split by spaces). That means that `hear` passed the check because `heart`
appears in the list.

This fixes tests that were surfaced as flaky. Usually these tests had
an off-by-one error when mining blocks while waiting for a
CSV-encumbered output.
