We distinguish between dangling and dust htlcs. This does not
change any logic but only introduces new types to later act on them
differently when we begin to fail dust htlcs earlier in a later
commit.
Refactor the part where we are failing back the incoming htlc
when the channel of the corresponding outgoing htlc is force
closed. We do this because in furture commits we separate the
logic when we fail back the incoming htlc (abandonForward).
Right now we fail abandon dust forwards and non-dust forwards
only when the commitment transaction is confirmed. Later we will
move the canceling of the upstream htlc when the commitment
transaction is broadcasted instead of waiting until the commitment
tx is confirmed. The reason for that is that dust cannot be enforced
onchain anyways so there is no reason to wait.
Because we need to remain backwards compatible with the old
`dust-threshold` value we set the default value for
`channel-max-fee-exposure` later in the program flow. Given
the restrictions of the sample config check we need to exclude
this value from the check.
Replace ambigious config value "dust-treshold" with a more clear
"channel-max-fee-exposure" exposure value. The old value is
deprecated and will be removed in the near future.
In this commit, we update an existing migration which at the time of
writing has not been included in a release. We update it so that it
converts the format used for MissionControl result encoding to use pure
TLV instead. The 3 structs that have been updated are: `mcHop`,
`mcRoute` and `paymentResult`.
So that we can use it in TLV encoding.
Also add this to the codec for channeldb migration 32 since we will be
using it there in an upcoming adjustment commit.
Add the TrueBoolean type along with its Record method. Also update the
Millisatoshi type with a Record method. Both of these will be used in an
upcoming commit which adjusts a mission control migration to use pure
TLV types.
