htlcswitch/link_test: update Bandwidth tests
This commit updates the tests for checking a links Bandwidth()
calculation, after the change that made us use the remoteACKedIndex
instead of the logIndex when calculating it. The main result of this
change is that we never consider incoming updates before they are
acked, when calculating the bandwidth. This is because this was
inconsistent with the state we actually end up signing later on.

htlcswitch: reject duplicate payments to same invoice
In this commit, we modify the way the link handles HTLC’s that it
detects is destined for itself. Before this commit if a payment hash
came across for an invoice we’d already settled, then we’d gladly
accept the payment _again_. As we’d like to enforce the norm that an
invoice is NEVER to be used twice, this commit modifies that behavior
to instead reject an incoming payment that attempts to re-use an
invoice.

Fixes #560.

40fb0ddcfc htlcswitch: Assign each pending payment a unique ID.
This simplifies the pending payment handling code because it allows it
be handled in nearly the same way as forwarded HTLCs by treating an
empty channel ID as local dispatch.

317b44e220 lnwallet: Change channel update methods to accept HTLC ID.
Previously, some methods on a LightningChannel like SettleHTLC and
FailHTLC would identify HTLCs by payment hash. This would not always
work correctly if there are multiple HTLCs with the same payment hash,
so instead we change these methods to identify HTLCs by their unique
identifiers instead.

htlcswitch: within link, with each new block, check to see if commit fee should change
In this commit we add a new case to the main select statement within a
channel link. This select statement will serve as a Sipping Bird which
will check the network fee rate (as returned by the fee estimator) and
compare that to the fee on the commitment transaction. Using the
shouldAdjustCommitFee function, we determine if we should update the
commitment fee. If so, then we’ll send an UpdateFee message and also
trigger a new commitment update.

We also add a new unit test: TestChannelLinkUpdateCommitFee to ensure
that we update the fee accordingly if the fee increases or decreases by
a large portion.

htlcswitch: add new shouldAdjustCommitFee helper function
In this commit, we add a new helper function to the link which will be
utilized in a later commit. This helper function will help us determine
if we should update the commitment fee, in response to a change in the
network fee return by our fee estimators.

htlcswitch: face race condition in unit tests by returning invoice
In this commit we modify the primary InvoiceRegistry interface within
the package to instead return a direct value for LookupInvoice rather
than a pointer. This fixes an existing race condition wherein a caller
could modify or read the value of the returned invoice.

d70ffe93e4 htlcswitch+channel: add channel states synchronization
In this commit BOLT№2 retranmission logic for the channel link have
been added. Now if channel link have been initialised with the
'SyncState' field than it will send the lnwire.ChannelReestablish
message and will be waiting for receiving the same message from remote
side. Exchange of this message allow both sides understand which
updates they should exchange with each other in order sync their
states.

htlcswitch: ensure payments in TestChannelLinkBidirectionalOneHopPayments aren't dust
This commit modifies the TestChannelLinkBidirectionalOneHopPayments
test to ensure that each payment sent is safely above the dust
threshold. Note that the dust threshold itself is now higher due to the
existence of the HTLC covenant transactions which the HTLC values
themselves must cover.

This change ensure that this test operates under “normal” operation
conditions in order to catch any bugs introduced during a major change.
