Detailed Description

This is a wrapper class around global free functions implemented by connection handler plugins (e.g.

thread pool). So instead of plugins implementing a Connection_handler subclass, they supply a set of function pointers to my_connection_handler_set() which instantiates Plugin_connection_handler.
