Add a test for the fee-bump rate of timeout HTLC claims on cp txn

HTLC timeouts on counterparty commitment transactions so that
instead of immediately attempting to bump every block we consider
the fact that we actually have at least `MIN_CLTV_EXPIRY_DELTA`
blocks to do so, and bumping at the appropriate rate given that.

Here we test that by adding an extra check to an existing test
that we do not bump in the very next block after the HTLC timeout
claim was initially broadcasted.

Clean up `PackageTemplate::get_height_timer` to consider type

`PackageTemplate::get_height_timer` is used to decide when to next
bump our feerate on claims which need to make it on chain within
some window. It does so by comparing the current height with some
deadline and increasing the bump rate as the deadline approaches.

However, the deadline used is the `counterparty_spendable_height`,
which is the height at which the counterparty might be able to
spend the same output, irrespective of why. This doesn't make sense
for all output types, for example outbound HTLCs are spendable by
our counteraprty immediately (by revealing the preimage), but we
don't need to get our HTLC timeout claims confirmed immedaitely,
as we actually have `MIN_CLTV_EXPIRY` blocks before the inbound
edge of a forwarded HTLC becomes claimable by our (other)
counterparty.

Thus, here, we adapt `get_height_timer` to look at the type of
output being claimed, and adjust the rate at which we bump the fee
according to the real deadline.

Stop passing current height to `PackageTemplate::build_package`

Now that we don't store the confirmation height of the inputs
being spent, passing the current height to

the height at which we should next bump the fee, but we just want
it to be "next block", so we might as well use `0` and avoid the
extra argument. Further, in one case we were already passing `0`,
so passing the argument is just confusing as we can't rely on it

Note that this does remove an assertion that we never merge
packages that were crated at different heights, and in the future

Validate `channel_update` signatures without holding a graph lock

We often process many gossip messages in parallel across different

contention-sensitive (not to mention the potential that we want to
send a payment and need to find a path to do so).

Because we need to look up a node's public key to validate a
signature on `channel_update` messages, we always need to take a
`NetworkGraph::channels` lock before we can validate the message.

For simplicity, and to avoid taking a lock twice, we'd always
validated the `channel_update` signature while holding the same
lock, but here we address the contention issues by doing a
`channel_update` validation in three stages.

First we take a read lock on `NetworkGraph::channels` and check if
the `channel_update` is new, then release the lock and validate the
message signature, and finally take a write lock, (re-check if the
`channel_update` is new) and update the graph.

Add a `PaymentId` for inbound payments

We expect our users to have fully idempotent `Event` handling as we
may replay events on restart for one of a number of reasons. This
isn't a big deal as long as all our events have some kind of
identifier users can use to check if the `Event` has already been
handled.

For outbound payments, this is the `PaymentId` they provide in the
send methods, however for inbound payments we don't have a great
option.

`PaymentHash` largely suffices - users can simply always claim in
response to a `PaymentClaimable` of sufficient value and treat a
`PaymentClaimed` event as duplicate any time they see a second one
for the same `PaymentHash`. This mostly works, but may result in
accepting duplicative payments if someone (incorrectly) pays twice
for the same `PaymentHash`.

Users could also fail for duplicative `PaymentClaimable` events of
the same `PaymentHash`, but doing so may result in spuriously
failing a payment if the `PaymentClaimable` event is a replay and
they never saw a corresponding `PaymentClaimed` event.

While none of this will result in spuriously thinking they've been
paid when they have not, it does result in some pretty awkward
semantics which we'd rather avoid our users having to deal with.

Instead, here, we add a new `PaymentId` which is simply an HMAC of
the HTLCs (as Channel ID, HTLC ID pairs) which were included in the
payment.
