strtolower() corrupts all UTF-8 share names that have a byte in the C0 (À ISO8859-1) to DE (Þ ISO8859-1) range, since the non-ASCII part of ISO8859-1 is incompatible with UTF-8. Prevent this by checking that a byte is in the ASCII range with isascii(), before the conversion to lowercase with tolower(). Properly handle case-insensitivity of UTF-8 share names by casefolding them, but fallback to ASCII lowercase conversion on failure or if CONFIG_UNICODE is not set. Refactor to move the share name casefolding immediately after the share name extraction. Also, make the associated constness corrections.
