channeldb: validate MPP options when registering attempts
We add validation making sure we are not trying to register MPP shards
for non-MPP payments, and vice versa. We also add validtion of total
sent amount against payment value, and matching MPP options.

We also add methods for copying Route/Hop, since it is useful to use
for modifying the route amount in the test.

channeldb: make database logic MPP compatible
This commit redefines how the control tower handles shard and payment
level settles and failures. We now consider the payment in flight as
long it has active shards, or it has no active shards but has not
reached a terminal condition (settle of one of the shards, or a payment
level failure has been encountered).

We also make it possible to settle/fail shards regardless of the payment
level status (since we must allow late shards recording their status
even though we have already settled/failed the payment).

Finally, we make it possible to Fail the payment when it is already
failed. This is to allow multiple concurrent shards that reach terminal
errors to mark the payment failed, without havinng to synchronize.

channeldb: convert to uniformly use new kvdb abstractions
In this commit, we migrate all the code in `channeldb` to only reference
the new `kvdb` package rather than `bbolt` directly.

In many instances, we need to add two version to fetch a bucket as both
read and write when needed. As an example, we add a new
`fetchChanBucketRw` function. This function is identical to
`fetchChanBucket`, but it will be used to fetch the main channel bucket
for all _write_ transactions. We need a new method as you can pass a
write transaction where a read is accepted, but not the other way around
due to the stronger typing of the new `kvdb` package.

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.

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.

channeldb+routing: expose HTLCs in payment subscriptions
This commit modifies the FetchPayment method to return MPPayment structs
converted from the legacy on-disk format. This allows us to attach the
HTLCs to the events given to clients subscribing to the outcome of an
HTLC.

This commit also bubbles up to the routerrpc/router_server, by
populating HTLCAttempts in the response and extracting the legacy route
field from the HTLCAttempts.
