With this commit, we can define an address type for default/imported
accounts in FundPsbt using '—change_type' flag. The value for this
flag can only be 'p2tr' at the moment. If not specified, we will use
P2WKH addresses for change outputs. Custom accounts don’t support
this flag as they have a unique scope.
By default, P2TR addresses are used for changes. However, some users
might encounter some problems with this change. We add the possibility
to define a custom address type in FundPsbt for default/imported accounts
(only P2TR for now). If no address type is specified for these accounts,
we will use P2WKH by default.
Since the cert pair is written with a subsequent call to
cert.WriteCertPair we can safely remove the two file paths from the
argument list of cert.GenCertPair.
This fixes a unit test flake that occurred sometimes if the temporary
directory was attempted to be deleted but the wallet or macaroon DB
hasn't been closed yet.

With this commit we bump the github.com/btcd/btcec/v2 library to v2.3.2
which implements the MuSig2 BIP version v1.0.0rc2. With this the
github.com/btcsuite/btcd/btcec/v2/schnorr/musig2 package becomes
v1.0.0rc2 and the github.com/lightningnetwork/lnd/internal/musig2v040
stays at the old v0.4.0 version.
We put the calls that don't use musig2 package specific types as
parameters or return values behind an interface so we can easily call
those directly in the RPC without needing to know the underlying
implementation version. Some calls can't be used in the interface
because they use the specific package version's types. These calls are
implemented in helper functions in the input package instead that do the
necessary type switches.
To allow us to properly test all test vectors, we can't default to true
on key sorting. Instead we add a parameter to the input package and move
the default value to the RPC server.
As a preparation for making it possible to version switch calls to the
MuSig2 API, we move some of the calls to the input package where in a
future commit we'll call the corresponding code in the correct package.
Since we explicitly keep an old version of a library in lnd for backward
compatibility we want to make sure the purpose and version of it is
clear and not misleading.
With this commit we copy the exact code of the MuSig2 code as found in
github.com/btcsuite/btcec/v2/schnorr/musig2 at the tag btcec/v2.2.2.
This corresponds to the MuSig2 BIP specification version of v0.4.0.
Before we change anything in the MuSig2 API, we first add an integration
test that makes sure the current version of the API combines keys
according to the v0.4.0 test vectors.
When a block is disconnected due to a reorg, DisconnectBlockAtHeight
is called for the block height. Prior to this patch, it would delete
every SCID in the graph with a block height greater than the
disconnected height. This meant that a reorg would delete every
zero-conf channel edge from the graph. The fix simply iterates up
until the StartingAlias and deletes every SCID between the
disconnected height and the StartingAlias height.
Use kvdb package v1.4.1. This update also forced the protobuf version to
be bumped which required `make rpc` to be run to update the generated
files. This also required a bump in the github pinned dependencies
config for the grpc and protobuf libs.
