Bug #56767: Make sure client plugins in 1054 are compatible with

Browse Source 
connectors plugins
      
Implemented changes needed to keep the client plugin API compatible with 
the existing plugins :
      
1. Provided an options() client plugin API to let the application pass
options to the plugin after loading it
2. Added "License" (const char *) to specify the client plugin's license
3. Added "mysql_api" as a placeholder that the client library can use
to pass function pointers to the plugin so that the plugin can call the 
C lib back.
4. Updated the existing client plugins to comply with the API change.
5. Added more detailed error message generation for Windows.
