Fixed that mysqld --no-defaults --help --verbose doesn't give a lot of irrelevant error messages.

Browse Source 
sql/mysql_priv.h:
  Make opt_help global
sql/mysqld.cc:
  Don't give (double) warnings about lower case file systems if --help is given.
  Don't give warning about non existing data directory if --help is given.
sql/sql_plugin.cc:
  Give a better warning if --help is used and plugin table doesn't exists
