In addition to a number of bug fixes and minor changes: * --numeric-owner (ignore user/group names on create and extract) * -S (sparsify files on extraction) * -s (regex filename substitutions) * Use new libarchive 'linkify' to get correct hardlink handling for both old and new cpio formats * Rework 'copy' test to be insensitive to readdir() filename ordering Most of the credit for this work goes to Joerg Sonnenberger, who has been duplicating features from NetBSD's 'pax' program.
