-  
-  Support code for the client side (libmysql) plugins
-
-  Client plugins are somewhat different from server plugins, they are simpler.
-
-  They do not need to be installed or in any way explicitly loaded on the
-  client, they are loaded automatically on demand.
-  One client plugin per shared object, soname *must* match the plugin name.
-
-  There is no reference counting and no unloading either.
