Baselog is modified from the simplelog.
Plus a little more we want：
- highest performance under Linux (but without async)
- lock free and nvme disk bandwidth saturation
- file rotating support
- loggers opt-ins are more flexible
In fact, high performance logging is a false proposition.
What we want is to maximize the total performance of a system with minimized logging overheads.
