htlcswitch/hop: make unknown required type const
Currently we use the AMP record type, this allows us to change it easily
as we add new known records. We also bump this to 0x0c instead of 0x0a.

lnwire: update quickcheck tests, use constant for Error

multi: update unit tests to pass deep equal assertions with messages

In this commit, we update a series of unit tests in the code base to now
pass due to the new wire message encode/decode logic. In many instances,
we'll now manually set the extra bytes to an empty byte slice to avoid
comparisons that fail due to one message having an empty byte slice and
the other having a nil pointer.

channeldb+htlcswitch: write wire messages using length prefix
In this commit, we modify the way we write wire messages across the
entire database. We'll now ensure that we always write wire messages
with a length prefix. We update the `codec.go` file to always write a 2
byte length prefix, this affects the way we write the `CommitDiff` and
`LogUpdates` struct to disk, and the network results bucket in the
switch as it includes a wire message.

htlcswitch: init mockFeeEstimator in other LinkChannelConfigs
If the tests don't execute quick enough, the link will try to sample the
network fee and cause a panic. This happens semi-regularly on travis.

multi: cap anchors feerate at configurable maximum
This commit caps the update fee the initiator will send when the anchors
channel type is used. We do not limit anything on the receiver side.

10 sat/vbyte is the current default max fee rate we use. This should be
enough to ensure propagation before anchoring down the commitment
transaction.

kvdb: add timeout options for bbolt (#4787)
* mod: bump btcwallet version to accept db timeout

* btcwallet: add DBTimeOut in config

* kvdb: add database timeout option for bbolt

This commit adds a DBTimeout option in bbolt config. The relevant
functions walletdb.Open/Create are updated to use this config. In
addition, the bolt compacter also applies the new timeout option.

* channeldb: add DBTimeout in db options

This commit adds the DBTimeout option for channeldb. A new unit
test file is created to test the default options. In addition,
the params used in kvdb.Create inside channeldb_test is updated
with a DefaultDBTimeout value.

* contractcourt+routing: use DBTimeout in kvdb

This commit touches multiple test files in contractcourt and routing.
The call of function kvdb.Create and kvdb.Open are now updated with
the new param DBTimeout, using the default value kvdb.DefaultDBTimeout.

* lncfg: add DBTimeout option in db config

The DBTimeout option is added to db config. A new unit test is
added to check the default DB config is created as expected.

* migration: add DBTimeout param in kvdb.Create/kvdb.Open

* keychain: update tests to use DBTimeout param

* htlcswitch+chainreg: add DBTimeout option

* macaroons: support DBTimeout config in creation

This commit adds the DBTimeout during the creation of macaroons.db.
The usage of kvdb.Create and kvdb.Open in its tests are updated with
a timeout value using kvdb.DefaultDBTimeout.

* walletunlocker: add dbTimeout option in UnlockerService

This commit adds a new param, dbTimeout, during the creation of
UnlockerService. This param is then passed to wallet.NewLoader
inside various service calls, specifying a timeout value to be
used when opening the bbolt. In addition, the macaroonService
is also called with this dbTimeout param.

* watchtower/wtdb: add dbTimeout param during creation

This commit adds the dbTimeout param for the creation of both
watchtower.db and wtclient.db.

* multi: add db timeout param for walletdb.Create

This commit adds the db timeout param for the function call
walletdb.Create. It touches only the test files found in chainntnfs,
lnwallet, and routing.

* lnd: pass DBTimeout config to relevant services

This commit enables lnd to pass the DBTimeout config to the following
services/config/functions,
  - chainControlConfig
  - walletunlocker
  - wallet.NewLoader
  - macaroons
  - watchtower
In addition, the usage of wallet.Create is updated too.

* sample-config: add dbtimeout option

htlcswitch/link: revert borking channels on received Errors
Since it turned out borking channels on every received error could cause
us to bork channels in case of a sync error with C-lightning, we revert
this for now.

Similarly as with kvdb.View this commits adds a reset closure to the

underlying db backend needs to retry the transaction.

multi: add reset closure to kvdb.View
This commit adds a reset() closure to the kvdb.View function which will
be called before each retry (including the first) of the view
transaction. The reset() closure can be used to reset external state
(eg slices or maps) where the view closure puts intermediate results.

ea467783e9 htlcswitch+peer: remove fwd pkgs once before tick, bump timer to 1hr
This commit changes the logic when garbage collecting forwarding
packages such that they are removed once when the function is called,
and then again upon subsequent ticks. This allows us to bump the
peer timer to 1 hour to limit the number of db transactions happening
in lnd. The forwarding packages need to be removed initially as
otherwise a flappy node will never have them garbage collected.

0f50d8b2ed htlcswitch: introducing interceptable switch.
In this commit we implement a wrapper arround the switch, called
InterceptableSwitch. This kind of wrapper behaves like a proxy which
intercepts forwarded packets and allows an external interceptor to
signal if it is interested to hold this forward and resolve it
manually later or let the switch execute its default behavior.
This infrastructure allows the RPC layer to expose interceptor
registration API to the user and by that enable the implementation
of custom routing behavior.

1a6701122c htlcswitch: change ForwardPackets to return error
As part of the preparation to the switch interceptor feature, this
function is changed  to return error instead of error channel that
is closed automatically.
Returning an error channel has become complex to maintain and
implement when adding more asynchronous flows to the switch.
The change doesn't affect the current behavior which logs the
errors as before.

multi: add explicit hodl invoice flag to invoice
Previously it wasn't possible to store a preimage in the invoice
database and signal that a payment should not be settled right away. The
only way to hold a payment was to insert the magic UnknownPreimage value
in the invoice database. This commit introduces a distinct flag to
signal that an invoice is a hold invoice and thereby allows the preimage
to be present in the database already.

Preparation for (key send) hodl invoices for which we already know the
preimage.
