This fixes a number of issues: * Zip archives with "length at end" can now be extracted correctly, since the Zip extractor can simply mark the size as "unknown." * Extract-to-disk can now accurately handle cases with partial time information (e.g., mtime is known but not atime) * We get more accurate handling of different hardlink extraction cases; sometimes a hardlink entry has definitive size information and sometimes not.

Also, update the copyright dates to 2007 for all of the files. Prompted by: several questions about what those extra words really mean 2006-03-21T16:55:46Z Tim Kientzle kientzle@FreeBSD.org 2006-03-21T16:55:46Z urn:sha1:2228e327554de7a7c2b875bbc29ca4d7b78d71f1 This commit implements storing/reading POSIX.1e-style extended attribute information in "pax" format archives. An outline of the storage format is in the tar.5 manpage. The archive_read_extract() function has code to restore those archives to disk for Linux; FreeBSD implementation is forthcoming. Many thanks to Jaakko Heinonen for finding flaws in earlier proposals and doing the bulk of the coding in this work. 2005-10-12T03:26:09Z Tim Kientzle kientzle@FreeBSD.org 2005-10-12T03:26:09Z urn:sha1:52a88d3b57dbd14caaea97ae604aafcfbc1503db link names, usernames, or group names that contain non-ASCII characters. In particular, this corrects an inconsistency reported by Ed Maste when archiving symlinks with odd characters: long symlinks would get preserved, short ones would be changed.
