+ * archive_lookup is used to determine if part of pathname refers to an regular
+ * file (archive). If so then its also used to split pathname into archive file
+ * and path used to locate file in archive. It also returns suffix of the file.
+ * How it works:
+ * We do stat of the parent of input pathname as long as we find an regular file
+ * Normally this should never happen. When routine returns true pathname modified
+ * and split into archive, inpath and suffix. Otherwise nothing happens
+ *
+ * For example:
+ *
+ * /music/path/Talco.zip/Talco - Combat Circus/12 - A la pachenka.mp3
+ * is split into archive: /music/path/Talco.zip
+ * inarchive pathname: Talco - Combat Circus/12 - A la pachenka.mp3
+ * and suffix: zip
