set_file_extension_and_mimetype_mapping() kept the extension as given,
and a file's extension was looked up as it was, then in lowercase, so a
mapping given as ".pdf" never matched and one given as "PDF" matched
only files ending in ".PDF". The extension is now lowercased and loses
a leading '.' when it is set, as Apache's AddType does, and a file's
extension is looked up in lowercase only.
