-  Get a key cache to be used for a specific table.

-  SYNOPSIS
-    multi_key_cache_search()
-    key				key to find (usually table path)
-    uint length			Length of key.
-    def				Default value if no key cache
-
-  NOTES
-    This function is coded in such a way that we will return the
-    default key cache even if one never called multi_keycache_init.
-    This will ensure that it works with old MyISAM clients.

-  RETURN
-    key cache to use
