Pass more info from log message to java logger #68

New libroc API (starting from 0.2), log messages provide more granular information. Instead of three arguments (level, component, message), logging callback in native library now receives a struct roc_log_message, defined here:

https://github.com/roc-streaming/roc-toolkit/blob/271ddf27eb3fae0273b5f8488a3114e70f1acfdb/src/public_api/include/roc/log.h#L58

Consider passing the following fields to jul:

• file and line (not strictly necessary, generally libroc logs are useful without this information too)
• time
• pid and tid (or maybe only tid)
