@brief
If frm_error() is called then we will use this to determine
the file extensions that exist for the storage engine. This is also
used by the default rename_table and delete_table method in
handler.cc and by the default discover_many method.
For engines that have two file name extentions (separate meta/index file
and data file), the order of elements is relevant. First element of engine
file name extentions array should be meta/index file extention. Second
element - data file extention. This order is assumed by
prepare_for_repair() when REPAIR TABLE ... USE_FRM is issued.
