High performance sync style Rust logging facility dedicated for Linux

Baselog is modified from the simplelog.

Plus a little more we want：

1. highest performance under Linux (but without async)
   • lock free and nvme disk bandwidth saturation
2. file rotating support
3. loggers opt-ins are more flexible

Why no async?

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.
