reduce lock for encoding
To reduce the number of locking for encoding manipulation, enc_table::list is splited to ::default_list and ::additional_list. ::default_list is pre-allocated and no need locking to access to the ::default_list. If additional encoding space is needed, use ::additional_list and this list need to use locking. However, most of case, ::default_list is enough.
