The test is identical to other onion failure fuzz tests, except that it
uses a custom equality function to get around the nil != []byte{} issue
with reflect.DeepEqual.
Fuzz tests for decoding and encoding of onion failure messages, based on
the fuzz harness for other lnwire messages. The onion failure messages
were uncovered by existing fuzz tests.
In this commit, we update the Sig type to support ECDSA and schnorr
signatures. We need to do this as the HTLC signatures will become
schnorr sigs for taproot channels. The current spec draft opts to
overload this field since both the sigs are actually 64 bytes in length.
The only consideration with this move is that callers need to "coerce" a
sig to the proper type if they need schnorr signatures.
This commit replaces `FundingLocked` found in docs using the following
command,
```shell
find . -name "*.go" -exec sed -i '' 's/FundingLocked/ChannelReady/g' {} \;
find . -name "*.go" -exec sed -i '' 's/FundingLock/ChannelReady/g' {} \;
```
