* "compression_program" support uses an external program * Portability: no longer uses "struct stat" as a primary data interchange structure internally * Part of the above: refactor archive_entry to separate out copy_stat() and stat() functions * More complete tests for archive_entry * Finish archive_entry_clone() * Isolate major()/minor()/makedev() in archive_entry; remove these from everywhere else. * Bug fix: properly handle decompression look-ahead at end-of-data * Bug fixes to 'ar' support * Fix memory leak in ZIP reader * Portability: better timegm() emulation in iso9660 reader * New write_disk flags to suppress auto dir creation and not overwrite newer files (for future cpio front-end) * Simplify trailing-'/' fixup when writing tar and pax * Test enhancements: fix various compiler warnings, improve portability, add lots of new tests. * Documentation: document new functions, first draft of libarchive_internals.3 MFC after: 14 days Thanks to: Joerg Sonnenberger (compression_program) Thanks to: Kai Wang (ar) Thanks to: Colin Percival (many small fixes) Thanks to: Many others who sent me various patches and problem reports.
