Previously, the API for ltree_strncasecmp() took two inputs but only one length (that of the smaller input). It truncated the larger input to that length, but that could break a multibyte sequence. Change the API to be a check for prefix equality (possibly case-insensitive) instead, which is all that's needed by the callers. Also, provide the lengths of both inputs.
