channeldb/migration13: migrate to mpp structure
This commit migrates the payments in the database to a new structure
that allows for multiple htlcs per payments. The migration introduces a
new sub-bucket that contains a list of htlcs and moves the old single
htlc into that.

channeldb+routing: store full htlc failure reason
This commit extends the htlc fail info with the full failure reason that
was received over the wire. In a later commit, this info will also be
exposed on the rpc interface. Furthermore it serves as a building block
to make SendToRoute reliable across restarts.

channeldb+routing: store all payment htlcs
This commit converts the database structure of a payment so that it can
not just store the last htlc attempt, but all attempts that have been
made. This is a preparation for mpp sending.

In addition to that, we now also persist the fail time of an htlc. In a
later commit, the full failure reason will be added as well.

A key change is made to the control tower interface. Previously the
control tower wasn't aware of individual htlc outcomes. The payment
remained in-flight with the latest attempt recorded, but an outcome was
only set when the payment finished. With this commit, the outcome of
every htlc is expected by the control tower and recorded in the
database.

lnwallet/reservation: add non-initiator balance check
If we are the initiator, we check that our starting balance after
subtracting fees are not less than two times the default dust limit.

This commit adds a similar check for the non-initiator case, checking
that the remote party has a starting balance of reasonable size.

contractcourt/commit_sweep_resolver: set sweep witness type based on witness script
We use the fact that we can tell whether the commit is local or remote
by inspecting the witness script. We cannot use the maturity delay
anymore, as we can have delayed to_remote outputs also now.

upper bound in any case.

input/script_utils_test: refactor TestHTLCSenderSpendValidation
To be able to change more than the witness used for each test case, we
extract commit and sweep tx generation into own methods that can be
called from each test case.

We do the same for TestHTLCReceiverSpendValidation

input/script_utils_test: extract script execution into assert method
This fixes an error case that wouldn't have been caught, since
vm.Execute applies more rules than the individual steps (most notably
the clean stack rule).

Instead we execute the engine as normal, and only step through if we
decide that the outcome is unexpected.

input/size: remove unused constants
Since we never attempt to sweep an HTLC we offered with the preimage on
the remote's commitment, we never use the constant
AcceptedHtlcSuccessWitnessSize for weight estimation. Similarly, we
never timout an HTLC offered by the remote on our own commitment, and
don't need the constant OfferedHtlcTimeoutWitnessSize.

channeldb: isolate duplicate payments
Duplicate payments is legacy that we keep alive for accounting purposes.
This commit isolates the deserialization logic for duplicate payments in
its own file, so that regular payment logic and db structure can evolve
without needing to handle/migrate the legacy data.

channeldb/test: refactor payment control test
Previously this was tested as a white box. Database access methods were
duplicated as test code and compared to the return value of the code
under test. This approaches leads to brittle test because it relies
heavily on implementation details. This commit changes this and prepares
for additional test coverage being added in later commits.

channeldb: rename PaymentAttemptInfo to HTLCAttemptInfo
To better distinguish payments from HTLCs, we rename the attempt info
struct to HTLCAttemptInfo. We also embed it into the HTLCAttempt struct,
to avoid having to duplicate this information.

The paymentID term is renamed to attemptID.

wtclientrpc: format wtclient.proto and remove json_name fields
We now use the jsonpb marshaler to convert the RPC responses to
JSON in lncli and REST. The jsonpb has a setting to use the
original name as defined in the proto file and the explicit
json_name definition is not necessary any more.
The jsonpb setting is called OrigName and needs to be true.
