Fix for #2126 (mysql_server_init call shouldn't be needed)

now mysql_server_init is called from mysql_init with fake parameters
mysql_once_init code included to mysql_server_init.
embedded-specific initialization is in init_embedded_server function


include/errmsg.h:
  this error won't happen
include/mysql.h:
  declarations removed
libmysql/client_settings.h:
  declaration of init_embedded_server/end_embedded_server added
libmysql/errmsg.c:
  this error won't happen
libmysql/libmysql.c:
  mysql_once_init -> mysql_server_init transformations
libmysqld/embedded_priv.h:
  declaration deleted
libmysqld/lib_sql.cc:
  mysql_server_init -> init_embedded_server
  mysql_server_end  -> end_embedded_server
libmysqld/libmysqld.c:
  check for server_inited not needed now
sql-common/client.c:
  mysql_server_init now called from mysql_init
sql/client_settings.h:
  fake mysql_server_init for server code
sql/net_serv.cc:
  we need MYSQL_CLIENT defined in embedded server
sql/sql_client.cc:
  not needed now
