* log: Add high-resolution timestamp option for log files This adds the %T option to the log format for millisecond timestamps. There's a feature test macro QB_FEATURE_LOG_HIRES_TIMESTAMPS so that applications know that they are available. Because this changes the internal logging API, applications that use custom loggers will also need to change their custom logging destinations to take a struct timespec instead of a time_t. The above feature test macro will help in deciding which is appropriate.
