libarchive 2.0 * libarchive_test program exercises many of the core features * Refactored old "read_extract" into new "archive_write_disk", which uses archive_write methods to put entries onto disk. In particular, you can now use archive_write_disk to create objects on disk without having an archive available. * Pushed some security checks from bsdtar down into libarchive, where they can be better optimized. * Rearchitected the logic for creating objects on disk to reduce the number of system calls. Several common cases now use a minimum number of system calls. * Virtualized some internal interfaces to provide a clearer separation of read and write handling and make it simpler to override key methods. * New "empty" format reader. * Corrected return types (this ABI breakage required the "2.0" version bump) * Many bug fixes.
