Many fixes. Portability: Thanks to Juergen Lock, libarchive now compiles cleanly on Linux. Along the way, I cleaned up a lot of error return codes and reorganized some code to simplify conditional compilation of certain sections. Bug fixes: * pax format now actually stores filenames that are 101-154 characters long. * pax format now allows newline characters in extended attributes (this fixes a long-standing bug in ACL handling) * mtime/atime are now restored for directories * directory list is now sorted prior to fix-up to permit correct restore of non-writable dir heirarchies

Only enable the ACL restore logic on FreeBSD versions >= 5.0. Earlier versions of FreeBSD don't support ACLs. Note that the ACL support code in archive_entry is standalone code and unaffected by this. (In particular, it should be possible to manipulate archives containing ACLs even if the ACLs cannot be restored on the current system.)
