Lightning messages are identified by a 2-byte type when encoded on the
wire. Rather than expecting callers to know message types when sending
messages to peers, have each message implement a trait defining the
message type. Provide an interface for reading and writing messages
as well as a Message enum for matching the decoded message, including
unknown messages.

Since we want to keep track of the Init-context features for every

moving channel storage to.

inner lock is a regular mutex, but the outer lock is RW so that we
can process for different peers at the same time with an outer read

Previously, in each of our fuzz tests we had a dummy test which
had a hard-coded hex string which it passed into the fuzz target

copied into the test and you could run cargo test to analyze the
failure. However, this was somewhat unwieldy as converting large
tests back and forth between hex and raw files is quite annoying.

Instead, we replace each of those tests with a test in each target
that looks for files in fuzz/test_cases and runs each file it finds.

The logger which decides what to refer to an on-chain claim tx was
assuming that all inputs would have a witness. While this was fine
for the one-input case, it broke the fuzzer which was connecting a
