This allows finegrained logging control of particular subdaemons or subsystems. To do this, we defer setting the logging levels for each log object until after early argument parsing (since e.g. "bitcoind" log object is created early). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Changelog-changed: Options: log-level can now specify different levels for different subsystems.
