NOTE: the logger instances is leaked on exit. This is ugly, but will be cleaned up by the OS/libc. Defining a logger as a global object doesn't work since the order of destruction of static/global objects is undefined. Consider if the logger gets destroyed, and then some later destructor calls LogPrintf, maybe indirectly, and you get a core dump at shutdown trying to access the logger. When the shutdown sequence is fully audited and tested, explicit destruction of these objects can be implemented by changing this from a raw pointer to a std::unique_ptr. Since the ~Logger() destructor is never called, the Logger class and all its subclasses must have implicitly-defined destructors.

This method of initialization was originally introduced in ee3374234c60aba2cc4c5cd5cac1c0aefc2d817c.
