This commit modifies the netann subsystem to use the peer's alias
for ChannelUpdates where appropriate (i.e. in case we are sending
the alias to the peer). It also modifies the loadActiveChannels
function in the peer package to handle upgrading a channel when the
scid-alias feature bit is turned on.
This commit was previously split into the following parts to ease
review:
- 2d746f68: replace imports
- 4008f0fd: use ecdsa.Signature
- 849e33d1: remove btcec.S256()
- b8f6ebbd: use v2 library correctly
- fa80bca9: bump go modules
To simplify the message signing API even further, we refactor the
lnwallet.MessageSigner interface to use a key locator instead of the
public key to identify which key should be signed with.
To make it possible to use a remote lnrpc server as a signer for our
wallet, we need to change our main interface to sign the message instead
of the message's digest. Otherwise we'd need to alter the
lnrpc.SignMessage RPC to accept a digest instead of only the message
which has security implications.
Add boolean parameter for test functions without changing any
existing functionality. All current tests set manual = false, but
Future tests can set manual = true to test manual requests to
update channel state.
Add a new boolean parameter without changing any existing
functionality. The parameter will be used to indicate
whether a request to update a channel's status was made
manually by a user (currently always false).
