09205b33aa net: Clarify message header validation errors (W. J. van der Laan)
955eee7680 net: Sanitize message type for logging (W. J. van der Laan)
Pull request description:
- Use `SanitizeString` when logging message errors to make sure that the message type is sanitized. I have checked all logging in `net.cpp`.
- For the `MESSAGESTART` error don't inspect and log header details at all: receiving invalid start bytes makes it likely that the packet isn't even formatted as valid P2P message. Logging the four unexpected start bytes (as hex) should be enough.
- Update `p2p_invalid_messages.py` test to check this.
- Improve error messages in a second commit.
