  Bug#15276: MySQL ignores collation-server
      Problem:
      mysqld --collation-server=xxx --character-set-server=yyy
      didn't work as expected: collation_server was set not to xxx,
      but to the default collation of character set "yyy".
      
      With different argument order it worked as expected:
      mysqld --character-set-server=yyy --collation-server=yyy 
      
      Fix:
      initializate default_collation_name to 0
      when processing --character-set-server
      only if --collation-server has not been specified
      in command line.

    Don't clear default_collation_name when processing 
        --character-set-server if collation has already
        been specified using --collation-server
