/*
Enable indexes, making it persistent if requested.
SYNOPSIS
enable_indexes()
mode mode of operation:
HA_KEY_SWITCH_NONUNIQ enable all non-unique keys
HA_KEY_SWITCH_ALL enable all keys
HA_KEY_SWITCH_NONUNIQ_SAVE en. non-uni. and make persistent
HA_KEY_SWITCH_ALL_SAVE en. all keys and make persistent
DESCRIPTION
Enable indexes, which might have been disabled by disable_index() before.
The modes without _SAVE work only if both data and indexes are empty,
since the MyISAM repair would enable them persistently.
To be sure in these cases, call handler::delete_all_rows() before.
IMPLEMENTATION
HA_KEY_SWITCH_NONUNIQ is not implemented.
HA_KEY_SWITCH_ALL_SAVE is not implemented.
RETURN
0 ok
!=0 Error, among others:
HA_ERR_CRASHED data or index is non-empty. Delete all rows and retry.
HA_ERR_WRONG_COMMAND mode not implemented.
